-# 2026-06-19 — Ricerca frattale multi-agente (63 agenti) su BTC/ETH
-
-Su richiesta: 50+ agenti in parallelo a cercare strategie NUOVE ispirate ai due documenti
-frattali (`Libro_frattali` + `Pythagoras_Trading_Prediction`), timing/asset diversi, ognuna
-validata sull'harness onesto. Eseguito come Workflow: **63 agenti, ~2h, 3.8M token.**
-
-## Cosa è stato testato
-16 concetti frattali estratti dai documenti (sotto la patina esoterica: coscienza, frequenze
-Solfeggio, numeri sacri → idee testabili): alfabeto candle U/D/0 (3-6, LONG), Fourier/cicli,
-ricorrenza di Poincaré (analoghi kNN), centro di inversione Evideon (mirror tempo+prezzo),
-indicatore H-C (~588/25 ≈ 23.5 barre), numeri-universali come periodi, invarianza di forma,
-entropia di Shannon ("coscienza") come gate, confluenza multi-TF, grammatica composizionale,
-fase-ricorrenza. × BTC/ETH × {5m,15m,1h} = **52 ipotesi**.
-
-Ogni segnale: scritto da un agente come funzione `signal()`, valutato da `eval_signal.py`
-(stesso harness onesto) con **guard automatico anti-look-ahead** (ricalcolo su prefissi).
-Superstiti → verifica avversariale con sblocco una-tantum del **hold-out 2025-26**.
-
-## Esito
-- **Verdetti**: 29 rumore, 12 "real" (netto-fee positivo ma non battono il buy&hold), 11 "edge"
-  (in-sample: battono B&H + null p<0.05 + leak=0).
-- **Guard anti-look-ahead**: nessun leak passato (gli agenti hanno prodotto segnali causali; i
-  pochi tentativi con futuro sono stati auto-squalificati e corretti).
-- **Hold-out (la prova del nove)**: dei **11 superstiti in-sample, 10 REFUTATI** — performance
-  catastrofica nel 2025-26 (hurst-DFA −0.49, hc-cycle −0.83, vol-accel −1.16, universal-periods
-  −0.42…−1.04, spectral-entropy −0.38/+0.29, multitf −0.49, solfeggio-BTC −0.64). Stessa firma di
-  sempre: **regime-luck del toro 2018-2024, sparito out-of-sample.**
-- **1 "confermato"** dalla verifica per-agente: `momentum_solfeggio_cycle` **ETH 1h** (holdout
-  Sharpe +1.19, ret +49% mentre il buy&hold ETH faceva −49%). Sembrava un trionfo.
-
-## Ma il "vincitore" cade al test cross-asset (kill decisivo)
-Il guard per-agente valuta un asset alla volta e non poteva vedere il quadro. Ho rieseguito **lo
-stesso identico codice** sui due major:
-
-| Signal (identico) | FULL Sharpe | HOLD-OUT Sharpe | HOLD-OUT ret |
-|---|---|---|---|
-| Solfeggio-cycle su **ETH** 1h | 1.54 | **+1.19** | +49% |
-| Solfeggio-cycle su **BTC** 1h | 1.17 | **−0.25** | −7.5% |
-
-Un edge robusto non fallisce sull'altro major. La stessa logica (long-only ~20% esposta, filtro
-SMA(588), timing su ciclo ~24) che ha "schivato" il crash ETH 2025 **perde su BTC nello stesso
-hold-out**. È **fortuna di regime di un singolo asset**, non skill. Aggravanti: costanti
-numerologiche ad-hoc (24/588/56, "odore" di overfit, già notato dal verificatore); e con 52 trial,
-trovare 1 segnale che passa un singolo regime di hold-out è atteso per puro caso (1/11 ≈ chance).
-
-## VERDETTO
-**La ricerca frattale multi-agente (52 ipotesi, 63 agenti) NON ha trovato alcun edge robusto.**
-I concetti frattali/esoterici si sono comportati esattamente come le famiglie convenzionali (Fasi
-1-3): edge in-sample da regime-luck del toro, refutati dal hold-out; e l'unico che passava il
-hold-out su un asset fallisce sull'altro. **Nessuna magia nei numeri Solfeggio/sacri.**
-
-Il valore: il processo disciplinato (guard anti-look-ahead + hold-out bloccato + **test cross-asset**)
-ha catturato un falso "trionfo" (+49% vs −49%!) che sul vecchio sistema contaminato sarebbe finito
-dritto in produzione. È la quinta conferma indipendente che su BTC/ETH non c'è un edge facile.
-
-## Stato della ricerca dopo tutte le fasi
-Testato: mean-reversion, momentum/trend, vol, lead-lag, hurst, shape-ML, e 16 famiglie frattali ×
-multi-TF/asset. **Niente di robusto, fee-surviving, OOS e cross-asset.** Le direzioni oneste
-restano: (a) accettare il ceiling = long risk-managed (no alpha); (b) allargare l'universo dati
-CERTIFICATO oltre BTC/ETH; (c) fonti di segnale ortogonali al prezzo (on-chain, basis multi-venue,
-opzioni multi-regime) — tutte richiedono nuovi dati certificati. Artefatti: `eval_signal.py`,
-workflow `fractal-strategy-search`, ~52 segnali in `/tmp/pyth_sig_*.py`.

-# 2026-06-19 — Ricerca v2.0.0: Fase 0 (harness) + Fase 1 (triage superstiti)
-
-Primo log di ricerca post-reset. Universo certificato: BTC/ETH, 1h. Hold-out 2025+ BLOCCATO.
-
-## Fase 0 — harness onesto (`scripts/analysis/research_lab.py`)
-
-Banco di prova causale per costruzione (modello a SERIE DI POSIZIONE: `pos[i]` decisa entro
-`close[i]`, guadagna `close[i]→close[i+1]`, fee sul turnover |Δpos|). Metriche
-Sharpe/CAGR/DD/exposure/turnover, finestra OOS, **null model a rotazione circolare**
-(p-value: il timing batte il caso?), baseline buy&hold, sweep fee.
-
-**Self-test del banco (valida l'HARNESS, non una strategia):**
-- buy&hold BTC: Sharpe 0.79 (sanity OK).
-- CHEAT look-ahead (pos = segno del rendimento futuro): Sharpe **58**, p=0.005 → l'engine
-  VEDE un edge reale quando esiste.
-- NOISE causale a basso turnover: Sharpe **0.14**, p=0.26 → l'engine NON inventa edge dal
-  nulla (niente leak, niente skill spuria).
-
-Il banco è affidabile. → ogni numero qui sotto è netto fee e causale.
-
-## Fase 1 — triage dei 2 superstiti (`scripts/analysis/phase1_survivors.py`)
-
-Sul feed pulito solo SH01 (shape-ML) e frammenti HONEST mostravano segnale residuo. Delle
-HONEST solo **DIP** è testabile su BTC/ETH (TR01/ROT02 richiedono alt esclusi). Re-implementati
-come serie di posizione, passati ai gate onesti.
-
-### DIP reversion (long-only) — ☠️ MORTO
-Griglia 3×3 (n, k) **tutta negativa** su entrambi gli asset (nessun plateau). Config centrale
-n50 k2.0: FULL Sharpe −0.17 (BTC) / −0.06 (ETH); a fee 0% appena +0.02/+0.09 (niente edge nemmeno
-lordo). OOS-VAL marginale (+0.36/+0.16) ma **null p=0.84-0.89** (peggio del caso). Rumore.
-
-### SH01 shape-ML (walk-forward LogReg) — ☠️ FEE-DEAD
-Pattern coerente su BTC/ETH, long/short e long-only:
-
-| Variante | Sh fee0% | Sh fee0.05% | Sh fee0.10% | trade/anno | null p |
-|---|---|---|---|---|---|
-| BTC L/S | +0.32 | −0.70 | −1.71 | 877 | 0.167 |
-| BTC long-only | +0.73 | −0.06 | −0.84 | 555 | 0.072 |
-| ETH L/S | +0.31 | −0.40 | −1.11 | 773 | 0.137 |
-| ETH long-only | +0.46 | −0.04 | −0.53 | 485 | 0.142 |
-
-C'è un **sussurro di segnale LORDO** (Sharpe 0.3-0.7 a fee zero) ma il turnover (485-877
-trade/anno) lo divora: a fee reale tutte negative, e **nessuna batte il null** (p>0.05). Net-fee:
-rumore.
-
-## VERDETTO Fase 1
-**Né DIP né shape-ML sopravvivono su BTC/ETH certificato net-fee.** Nessuno dà Sharpe netto >0,
-nessuno batte il null (p<0.05), nessuno batte il **buy&hold** (Sharpe 0.79/0.84 — di fatto la
-"strategia" più forte vista finora). Si conferma: i "superstiti" della vecchia libreria erano,
-come il resto, non-edge. Chiusi.
-
-## Lead onesto per la Fase 2
-L'unico segnale non-nullo è il **gross shape-ML** (Sharpe 0.3-0.7 a fee zero), ucciso dal
-turnover. Direzione: esprimere quel segnale a **turnover molto più basso** (orizzonte di holding
-lungo, soglia forte, o come GATE di regime invece che flip per-barra) per vedere se il sussurro
-lordo sopravvive alle fee. È un lead, NON un edge. Inoltre: la barra reale da battere è il
-**buy&hold** (Sharpe ~0.8) — una strategia di timing deve fare meglio di "stai sempre long",
-net-fee.

-  15m: fee-death, −5.6 BTC / −4.6 ETH), gross ≈0, null p 0.45-0.82. **Smentisce definitivamente
-  la tesi storica del progetto ("l'edge è sempre mean-reversion")**: era artefatto del feed.
-- **TSMOM / MA-cross / Donchian (trend, long-only): segnale REALE ma MODESTO.** Le versioni
-  long-only (basso turnover) battono o eguagliano il buy&hold:
-  - **MA-cross long-only**: ETH FULL **1.12** / OOS 0.89 / p **0.007**; BTC FULL **0.90** / OOS
-    1.99 / p **0.040**. Plateau sulla griglia (ETH 12/48 e 48/192 entrambi 1.1), coerente sui
-    DUE asset, basso turnover (53-106 trade/anno). **Unici 2 a passare: battono B&H + OOS>0 + p<0.05.**
-  - Donchian long-only: FULL 0.84-0.94, OOS ottimo (BTC 2.37) ma p 0.08-0.10 (pochi trade → null
-    rumoroso). TSMOM long-only: ETH 0.83 (≈B&H). Le L/S perdono (turnover + short su asset in trend).
-- **VOL-TARGET overlay**: ≈ buy&hold (FULL 0.77-0.84), p alto → non distinguibile dal B&H, ma è
-  un riduttore di vol/DD (mantiene lo Sharpe scalando l'esposizione).
-- **HURST-gate, LEAD-LAG BTC↔ETH**: niente. (Hurst-mom ETH p=0.043 ma sotto il B&H; lead-lag
-  fee-dead.)
-
-### Verdetto Fase 2
-L'unica cosa reale su BTC/ETH certificato è il **trend-following long-only** (MA-cross in testa):
-un **long con gestione del rischio** che batte il buy&hold di poco (Sharpe ~0.9-1.1 vs 0.8)
-evitando i drawdown peggiori. È un effetto noto in letteratura (time-series momentum), NON alpha
-market-neutral. **Caveat multiple-testing**: 2 flag su ~24 test ≈ soglia del caso; ma la stessa
-famiglia vince su ENTRAMBI gli asset con plateau → è un LEAD genuino, non confermato. La barra
-vera resta il B&H, e l'OOS-VAL alto di BTC (1.99) puzza di "2024 anno di trend forte" → serve la
-prova del hold-out 2025-26 + regimi bear + stress fee/slippage + deflated-Sharpe (Fase 3).
-
-## Analisi OPTIONS (`options_analysis.py`)
-
-Dati reali cerbero-bite mainnet, ma finestra **~2026-05-01→06-11 (~6 sett., REGIME UNICO calmo)**.
-
-### Livelli misurati (reali)
-- **VRP (IV − RV) positivo il 100% del tempo**: BTC +10, ETH +14 punti di vol annua. Le opzioni
-  sono sistematicamente CARE in questa finestra → vendere vol/covered-call avrebbe incassato premio.
-- **Skew put positivo**: BTC IV put-10%OTM 44% vs call 35% (skew +10 pt); ETH 54 vs 49 (+5). Il
-  crash è prezzato (assicurazione cara).
-- **Costo put protettiva** (mensile, %-del-notional): ~10% OTM = **0.98% BTC / 1.36% ETH**; ATM
-  3.3%/5.0%; ~15% OTM 0.83%/0.71%. Liquidità: ATM spread ~3%, OTM 7-12%. Mensile ben popolato
-  (499-2043 strike), settimanale OTM sottile. Funding perp ≈ 0 (nessun carry).
-
-### Verdetto OPTIONS
-**Nessun edge su opzioni è validabile ora**: 6 settimane, regime unico calmo. Il segnale
-VRP-positivo / sell-vol è ESATTAMENTE ciò che brilla in calma e salta in aria nei crash (è il
-rischio che viene pagato) — non testabile senza un crash nel campione. Ruoli legittimi (entrambi
-NON validabili ora, solo forward):
-- **(a) Tail-cap / catastrofe**: put OTM standing su un book long (il candidato trend ha DD grossi).
-  Costa ~1-1.5%/mese a 10% OTM — gateabile coi premi reali misurati qui. Overlay per-trade 24h
-  INFATTIBILE (strike OTM corti inesistenti/illiquidi); standing settimanale/mensile FATTIBILE.
-- **(b) Harvest del VRP** (covered call / put-spread): +10-14 pt ci sono ORA, ma è una scommessa
-  short-vol che richiede un crash nel campione per essere giudicata onestamente. Non l'abbiamo.
-
-**Raccomandazione**: le opzioni NON sono un'avenue di ricerca a breve (manca storia multi-regime).
-Mosse: (1) lasciare cerbero-bite ad accumulare (gratis, reale, costruisce in avanti il dataset
-multi-regime); (2) rivalutare quando la finestra attraversa un crash/alta-vol; (3) intanto, l'unico
-uso giustificato è come OVERLAY (tail-cap su una strategia spot), gateato sui premi reali qui sopra.
-
-## Prossimo passo
-Fase 3 sul solo candidato reale (trend-following long-only, MA-cross): sblocco UNA volta del
-hold-out 2025-26, comportamento nei bear (2018/2022), stress fee×2 + slippage + lag, deflated-Sharpe
-per il multiple-testing. Se regge → è la prima strategia onesta del progetto v2.0.0 (modesta:
-migliora il buy&hold, non lo stravolge). Se non regge → anche il trend era sample-luck.

-
-## Esito: ☠️ NON CONFERMATO — era regime-luck del mercato toro
-
-### (1) Pre-hold-out (2018-2024): forte e robusto
-Plateau pieno: BTC Sharpe 0.91-1.16, ETH 1.19-1.48 su tutte le config. **Deflated-Sharpe**
-(N=60 trial): BTC DSR **0.990**, ETH **0.982** → l'effetto trend era REALE e robusto al
-multiple-testing **sul 2018-2024**.
-
-### (2) HOLD-OUT 2025-26 (sbloccato una volta) — FALLISCE
-| | buy&hold | trend 24/96 | trend 96/288 (slow) |
-|---|---|---|---|
-| BTC Sharpe | −0.37 | **−0.81** | −0.00 |
-| BTC ret | −32.9% | −33.6% | −5.0% |
-| ETH Sharpe | −0.32 | **−0.95** | −0.01 |
-| ETH ret | −49.3% | −52.0% | −11.3% |
-
-Il 2025-26 è stato un periodo in DISCESA (buy&hold negativo). Il trend long-only — che "dovrebbe"
-schivare i bear — si è fatto **frullare** (whipsaw): perde quanto o PIÙ del buy&hold, Sharpe negativo
-su ogni config. Solo la MA lentissima (96/288) limita i danni a ~flat (−5/−11%), ma è cherry-pick
-post-hoc e comunque NON positiva.
-
-### (3) Per anno — il meccanismo
-Il trend cattura ~70-80% degli anni TORO (2019-2024) e attutisce i bear IN-SAMPLE (2018 −1% vs
-−39%; 2022 −47% vs −65%). MA nel 2025 OUT-OF-SAMPLE ha fatto **peggio** del buy&hold (BTC −25% vs
-−7%; ETH −41% vs −11%): frullato in un mercato choppy/discendente. È il classico fallimento del
-trend-following nei bear laterali. → l'edge 2018-24 era **beta del toro con risk-management**, non
-alpha persistente.
-
-### (4) Stress
-FULL regge modestamente (Sharpe 0.65-0.91 anche a fee2x+lag), ma HOLD-OUT è negativo ovunque
-(−0.81 → −1.34) e peggiora sotto stress. Fragile.
-
-### (5) Deflated-Sharpe
-DSR>0.95 sul pre-hold-out → conferma che l'effetto era statisticamente reale **nel campione di
-training**. Lezione chiave: **robustezza statistica in-sample ≠ persistenza out-of-sample.** Il
-hold-out bloccato ha colto ciò che DSR da solo non poteva — il cambio di regime.
-
-## VERDETTO FINALE (Fasi 0-3)
-**Nessun edge validato, fee-surviving e out-of-sample esiste su BTC/ETH tra le famiglie testate.**
-Il trend-following era il miglior candidato: reale 2018-24 (toro), ma **bocciato sul hold-out
-2025-26** (whipsaw, sotto il buy&hold). La barra realistica resta il **buy&hold** (Sharpe ~0.8
-sullo storico, ma −0.3/−0.4 nel 2025-26: anche "stai long" è stato duro di recente).
-
-Il processo disciplinato ha funzionato: **ha evitato di deployare un falso edge** (che, sul vecchio
-sistema contaminato, sarebbe finito in produzione). Questo è il valore del reset.
-
-## Implicazioni / direzioni
-- **Non deployare** il trend come edge: è regime-dipendente, non batte il buy&hold OOS.
-- Con **solo BTC/ETH prezzo**, il pozzo dei segnali è poco profondo: timing puro non ha edge robusto.
-- Opzioni: nessun ruolo a breve (confermato). Tenere cerbero-bite ad accumulare per uno studio
-  multi-regime futuro.

+# 2026-06-19 — Sintesi ricerca post-reset (5 track) e verdetto
+
+Prima ondata di ricerca sui dati **certificati** BTC/ETH (Deribit mainnet, ~2 bps vs
+Coinbase USD), con harness onesto condiviso `src/backtest/harness.py` (ingresso eseguibile
+a `close[i]`, fee 0.10% RT, exit intrabar TP/SL, OOS/per-anno). Branch
+`strategy-research-2026-06`.
+
+## I 5 track
+
+| Track | Famiglia | Esito |
+|-------|----------|-------|
+| **A** | Trend/Momentum (TSMOM, Donchian, EMA, vol-scaled) | 5m/15m morti (fee); 1h = residuo reale ma celle singole non robuste |
+| **B** | ML walk-forward (logistic/GBM su feature di forma) | edge debole ma REALE su BTC (+83% OOS, Sharpe 0.57), ~+0.58 €/d su 2000 |
+| **C** | Mean-reversion / range (fade, RSI2, VWAP) | **MORTO** — negativo anche a fee=0. Conferma: la vecchia libreria fade era artefatto |
+| **D** | **Trend portfolio vol-targeted BTC+ETH** | ✅ **DEPLOYABLE** — robusto, positivo ogni anno |
+| **E** | Cross-sectional BTC↔ETH + ensemble | RV debole (muore a 1.5bps/gamba); ensemble dimezza il DD ma non alza il ritorno |
+
+## Il vincitore: Track D — trend portfolio (l'unico che guadagna in modo robusto)
+
+TSMOM multi-orizzonte (blend 1-3-6 mesi su barre 1h), **vol-targeting** (posizione ∝
+1/vol realizzata, target 20% annuo), portafoglio **50/50 BTC+ETH**, fee 0.10% RT. Un solo
+set di parametri per entrambi gli asset.
+
+- **LONG-SHORT 50/50:** CAGR +14.2%, **Sharpe 1.00**, maxDD 18.9%, positivo ogni anno 2019-2026.
+- **LONG-FLAT 50/50 (migliore risk-adj):** CAGR +15.9%, **Sharpe 1.32**, **maxDD 13.3%**.
+- Robusto: plateau di Sharpe ~1.0 su griglia target-vol/leva/orizzonti; regge fee fino a 0.40% RT;
+  su entrambi gli asset; **non** è un picco fortunato (a differenza delle "star" di Track A).
+- Tesi confermata: il valore del trend è **tagliare il drawdown** (B&H DD ~78% → trend DD ~13-19%)
+  con Sharpe ≥ B&H → si può scalare il rischio (target-vol) e diversificare BTC+ETH.
+- Caveat onesto: l'edge è più forte 2018-21 (Sharpe 1.63) che 2022-26 (Sharpe 0.57). Dimensionare
+  sul regime recente.
+
+## Il verdetto sul target €50/giorno
+
+Una strategia che **guadagna** in modo robusto ESISTE (Track D). Ma il target "€50/giorno
+medio partendo da 2000 in 1-2 anni" **non è raggiungibile onestamente**: sono ~2.5%/giorno.
+
+La leva NON è la scorciatoia (alza il DD verso la rovina). La vera leva è **target-vol +
+capitale + tempo**:
+
+| target-vol | leva usata | CAGR | Sharpe | maxDD | €/giorno (2k) |
+|-----------|-----------|------|--------|-------|---------------|
+| 20% | 0.23x | +14% | 1.00 | 19% | +0.73 |
+| 40% | 0.45x | +28% | 1.00 | 35% | +3.73 |
+| 60% | 0.68x | +40% | 1.00 | 48% | +7.96 |
+| 80% | 0.90x | +50% | 0.99 | 60% | +13.78 |
+
+Per **€50/giorno steady-state** servono ~**137k di capitale** (config conservativa, DD~19%),
+oppure DD da rovina. Partendo da 2000 a CAGR ~28% (target-vol 40%, DD 35%) il capitale che
+genera €50/giorno arriva in ~10-13 anni, non in 1-2.
+
+## Conclusione operativa
+
+1. **Esiste un edge dispiegabile e onesto**: il trend portfolio vol-targeted (Track D).
+   È il primo risultato robusto post-reset.
+2. **Non esiste alcuna scorciatoia** verso €50/giorno su 2000 in 1-2 anni con questi dati
+   (BTC/ETH 5m-1h). Il limite è strutturale: due asset, alta correlazione, fee.
+3. Prossimi passi onesti se si vuole alzare il soffitto: (a) dimensionare Track D a un
+   target-vol/DD tollerabile e farlo girare in paper, (b) cercare edge di **magnitudine
+   diversa** (non più diversificazione di edge deboli) — il che richiede dati che oggi non
+   abbiamo certificati (universo più ampio, microstruttura, funding/opzioni backtestabili).

+# 2026-06-19 — Track A: Trend / Momentum su BTC & ETH (dati certificati)
+
+Prima ricerca di strategie NUOVE post-reset (track A = trend/momentum). Tool:
+`scripts/research/trackA_trend.py` (harness onesto `src/backtest/harness.py`, fee 0.10% RT,
+IS/OOS 65/35, griglia su entrambi gli asset, fee sweep, stress leva). Run:
+`uv run python scripts/research/trackA_trend.py`.
+
+## Cosa è stato testato
+- **TSMOM** (segno del ritorno N-barre, hold H) long/short e long-only.
+- **EMA crossover** (fast/slow) come filtro di trend.
+- **Donchian breakout** (entry ONESTO: breakout rilevato con `close[i]`, fill a `close[i]`).
+- **Vol-scaled / regime-gated TSMOM** (momentum preso solo se |z| > gate, z = ritorno/vol).
+- Griglia ampia su **BTC e ETH**, **1h / 15m / 5m**. 480 celle OOS totali.
+
+Tutto entry-eseguibile: direzione e prezzo decisi con dati ≤ `close[i]`, fill a `close[i]`.
+Nessun uso di `returns[i]` (che codifica `close[i+1]`). Hold approssimato come catena di
+posizioni non sovrapposte di H barre (la fee si ammortizza su H barre — costo onesto).
+
+## Risultati — la fotografia onesta
+
+**Celle positive OOS per timeframe:**
+| TF | celle positive / totali |
+|----|----|
+| **1h**  | 39 / 160 |
+| **15m** | **0 / 160** |
+| **5m**  | **0 / 160** |
+
+→ **Trend intraday (5m/15m) è MORTO**: lo drag della fee (più trade = più 0.10% RT) annienta
+qualsiasi segnale. Drawdown 80-99%, Sharpe da −0.6 a −2.2. Niente da salvare.
+
+**Su 1h** c'è qualche cella positiva, ma il contesto la ridimensiona:
+- La finestra **OOS è un singolo regime**: il taglio 65% cade a **set/dic 2023**, quindi
+  l'OOS è ~2023→2026 (in gran parte toro 2024). Tutto il 2018-2022 (orso 2018, crash 2020,
+  toro 2021, orso 2022) è IN-SAMPLE. "Positivo OOS" qui ≈ "il trend ha fatto soldi nel toro 2024".
+- **Benchmark buy & hold sulla stessa finestra OOS**: BTC **+134%**, ETH **−21%**.
+  - Tutte le `TSMOM_LONG` e metà delle celle BTC fanno **MENO** del B&H → è **beta**, non edge.
+  - Le poche che battono il B&H lo fanno **solo su ETH** (dove il B&H era negativo): catturano
+    anche i ribassi. Quello è timing reale — ma vedi sotto.
+
+**Le "star":** VOLSCALED_TSMOM BTC 1h (N=20,H=48,vw=100,z=0.5) = +367% OOS, Sh 0.91, DD 32%,
+€/d(2k) +2.56; ETH 1h (N=20,H=48,vw=50,z=1.0) = +197% OOS, Sh 0.60. **MA sono celle fortunate:**
+i vicini di griglia crollano (stesso N/H, vw=50 invece di 100 → +21% invece di +367%; z=1.0 → +34%).
+Non è un altopiano robusto, è un picco isolato. E il P&L è concentrato nel 2024 (+110% su BTC),
+con 2025/2026 deboli o negativi per molte celle.
+
+**Consistenza cross-asset (un edge vero regge su ENTRAMBI):** su 480 celle, solo **2** sono
+positive OOS su BTC *e* ETH:
+- `TSMOM_LONG 1h N=200 H=48` → ma è long-only ≈ beta (fa meno del B&H su BTC).
+- `DONCHIAN 1h N=200 H=12` → l'unico candidato "vero" simmetrico, ma **marginale**:
+  OOS BTC +9% / ETH +15%, **Sharpe 0.15-0.19**, troppo debole per dispiegarlo.
+
+**Fee sweep / leva:** le star reggono lo sweep 0.0005-0.002 (è 1h, poche operazioni), e lo Sharpe
+è invariante alla leva (come deve) — ma la leva 3x porta i DD a 75-91% e affonda le celle marginali.
+
+## Verdetto
+
+**Nessun edge trend/momentum dispiegabile, onestamente, su BTC/ETH oggi.**
+- 5m/15m: morti per fee. Chiuso.
+- 1h: esiste un **residuo di segnale trend** (le celle che battono il B&H negativo di ETH non sono
+  solo beta), ma è (a) testato su **un solo regime OOS** (toro 2023-2026), (b) **non robusto** di
+  griglia (picchi isolati), (c) sull'unica cella simmetrica robusta-su-entrambi (Donchian N=200)
+  **troppo debole** (Sharpe ~0.17). Sharpe netti ~0.3-0.9 nel caso migliore = sotto la soglia per
+  rischiare capitale reale.
+
+Conferma la lezione del reset (il superstite storico era trend-following, non mean-reversion): il
+trend è la direzione *meno sbagliata*, ma sui dati certi non basta a fare un edge. Coerente con
+Track C (mean-reversion = artefatto).
+
+## Prossimi passi possibili (non ancora edge)
+- Walk-forward multi-regime (non un singolo taglio 65/35) per stressare Donchian-1h-N200 su orso 2018/2022.
+- Trend 1h **con filtro di volatilità/regime più ricco** o portafoglio BTC+ETH per diversificare il
+  rischio di regime — ma solo se emerge robustezza di griglia, non altri picchi fortunati.
+- Restare scettici: finché un trend non è positivo su griglia + su entrambi gli asset + su ≥2 regimi
+  OOS, **non si dispiega**.

+held-out tail mai usato per scegliere i config.
+
+## Metodologia (anti look-ahead — la lezione della v2.0.0)
+
+- **Feature** (21): ritorni multi-lag (1/2/3/6/12/24), geometria candela (body/upper/lower
+  shadow su range, range normalizzato, body lag-1), momentum48 + accelerazione, RSI14,
+  estensione ATR-normalizzata vs EMA24, vol realizzata 24/72 + ratio, posizione del close

+- **Label**: segno del ritorno forward su H barre, `sign(close[i+H]/close[i])`.
+- **Strict walk-forward**: per predire il blocco che inizia a `b`, si addestra
+  scaler+modello SOLO su indici `< b-H` (gap di H → label completamente realizzata nel
+  passato), finestra rolling delle ultime W barre. Retrain ogni K=250 barre. Mai fit sul
+  futuro. **Nessun leakage** (verificato: la label più recente del train usa `close[b-1]`).
+- **Esecuzione**: entry a `close[i]` nella direzione predetta, hold fino a H barre
+  (no TP/SL); il no-overlap dell'harness distanzia i trade ≥ H barre.
+- **Modello**: `LogisticRegression(class_weight='balanced')`. Soglia di probabilità per
+  filtrare i segnali deboli (long se p>0.5+thr, short se p<0.5-thr, altrimenti flat).
+- **Selezione su DEV** (primo 75%), **conferma una volta sola** sull'held-out tail (ultimo 25%).
+- Griglia: W∈{4000,8000,16000}, H∈{6,12,24,48}, thr∈{0,0.03,0.06,0.10}, BTC & ETH, 1h.

+**Pattern netto e robusto della griglia**: la positività compare SOLO nelle celle a basso
+turnover → **W grande (16000) + H lungo (24) + soglia alta (0.10)**. Tutto ciò che gira
+veloce (thr basso, H corto, e soprattutto il **15m**) **muore sulle fee**.
+
+- **15m**: 0/12 celle positive in dev (la migliore −47%, le altre −99%). Stesso win-rate
+  52–56% del 1h, ma il turnover lo polverizza. Conferma di prim'ordine: l'edge per-trade è
+  minuscolo, sopravvive solo se si tradano poche barre.
+- **1h, dev**: 19/96 celle net-positive con Sharpe>0. Famiglie threshold-robuste:
+  `BTC W16000 H12`, `BTC W8000 H12`, `BTC W16000 H24`, più ETH W16000 H12/H48 marginali.

+
+**Non è solo beta.** Il B&H sul tail è +3.9% (BTC) e −38.4% (ETH), eppure le celle migliori
+fanno +37…+84% (BTC) con **long ~44–54%** (bilanciato long/short), e ETH +23.7% **mentre ETH

+  Sopravvive fino a ~0.15% RT, poi muore. Margine sottile.
+- `BTC W8000 H12 thr0.06`: positivo solo a 0.05%, già −35% a 0.10%. Fragile.
+- ETH e le celle a turnover medio: muoiono tra 0.10 e 0.15%.
+
+### Stabilità per-anno (full walk-forward, BTC W16000 H24 thr0.10)

+CAGR full ~22%, ma **DD 56%** e fortissima concentrazione su 2021/2025 con un 2023 a −38%.
+
+## Verdetto onesto — NON deployabile verso l'obiettivo
+
+1. **L'edge è reale ma minuscolo.** A differenza della vecchia libreria (artefatto puro), qui
+   il segnale sopravvive a strict walk-forward, a fee 0.10% RT e batte il B&H sul tail. È un
+   risultato genuino e va registrato: la direzione ML **non è morta**.
+2. **Ma è incompatibile col target.** €/giorno su €2000 = +0.26…+0.58 baseline (anche la stima
+   rosea full-WF CAGR 22% → ~€1–3/g). Il target è **€50/g** → siamo ~100x sotto.
+3. **Fragilità**: vive solo a basso turnover (thr alto, H lungo, W grande), DD 23–56%,
+   ritorni concentrati in pochi anni con un anno a −38%, e l'edge si assottiglia già a
+   0.15% RT. Un singolo cambio di regime lo annulla.
+4. **ETH ≠ "specialmente buono"** (contrariamente all'indizio dello shape-ML precedente): qui
+   ETH è più sottile e più rumoroso di BTC sull'held-out; l'unico merito è aver shortato
+   correttamente il drawdown 2024-25.
+
+**Conclusione**: la logistic-regression walk-forward su feature di forma+momentum trova un
+debole edge **momentum direzionale a basso turnover** su BTC (più tenue su ETH), onesto e
+netto-fee, ma **troppo piccolo, troppo concentrato e troppo fee-sensibile** per essere
+deployato standalone. Al massimo un **componente** di un futuro ensemble, e solo nelle
+configurazioni a bassissimo turnover. Nessun config raggiunge, neanche lontanamente, i €50/g.
+
+## Prossimi passi possibili (non eseguiti)
+
+- Provare **predizione di magnitudine/asimmetria** (large-up vs large-down) e position-sizing
+  proporzionale alla confidenza, invece del semplice segno.
+- **GradientBoosting / feature non lineari** (flag `--gbm` predisposto) — ma attenzione
+  all'overfit; il rischio è di "trovare" edge che il walk-forward onesto non conferma.
+- **Ensemble** del segnale ML a basso turnover con un filtro di regime (vol/trend) per tagliare
+  il 2023. Ma serve dimostrare che il filtro non è scelto col senno di poi.
+- Restare scettici: finché €/g resta ~100x sotto target, l'ML da solo NON è la risposta.

+Follow-up to Track A. Thesis under test: trend-following's real value in crypto is **drawdown
+reduction** vs buy & hold (it sidesteps crashes), and that lower DD lets you apply **leverage** and
+**diversify** BTC+ETH into a deployable, risk-adjusted *earning* system — even if each single signal

+- **Portfolio** = 50/50 BTC+ETH net-return series, rebalanced each bar on common timestamps.
+
+Leakage sanity check passed: an *oracle* target using next-bar sign explodes (10^119×) — proving the
+engine holds `target[i-1]` over bar `i` — while our signals (TSMOM blend, MA-slope, Donchian) only use
+`close[i]` and earlier. Zero-position equity = exactly 1.0.
+
+## What was tested
+TSMOM multi-horizon blend (1/3/6-month-equiv on 1h bars), MA-slope (EMA200 slope), Donchian breakout
+with trailing channel stop — each vol-targeted, long-short **and** long-flat, per-asset and combined.
+Grid: target-vol × leverage-cap × horizon-set; explicit EARLY(2018-21)/LATE(2022-26) split;
+fee & leverage sweep; full per-year 2018-2026.
+
+## Results — the honest picture
+
+**1) The thesis holds: massive DD reduction, and diversification helps.**
+| Strategy (50/50 port, tvol20%, LS) | CAGR | Sharpe | maxDD | volA |
+|---|---|---|---|---|
+| **B&H 50/50** | +48% | 0.92 | **77.8%** | 70% |
+| TSMOM 1-3-6m blend | +14.2% | **1.00** | **18.9%** | 14% |
+| MA-slope | +14.1% | 0.79 | 21.9% | 19% |
+| Donchian-trailing | +14.7% | 0.89 | 17.7% | 17% |
+
+Trend cuts maxDD from ~78% to ~18% while keeping a Sharpe **above** buy&hold (1.00 vs 0.92). The
+portfolio Sharpe (1.00) **beats both sleeves** (BTC 0.95, ETH 0.75) — diversification works as claimed.
+The **long-flat** variant is even cleaner: Sharpe **1.32**, maxDD **13.3%** (no short funding/borrow risk).
+
+**2) It is genuinely robust (not a lucky cell).**
+- *Per-year (headline LS):* every full year **positive** 2019-2025 (+19/+36/+19/+6/+2/+14/+4%) and 2026 +8%.
+- *Grid:* Sharpe ≈1.00 across **all** target-vol (10-40%) × leverage caps — flat plateau (vol-targeting
+  just scales). DD scales ~linearly with target-vol (10%→DD10%, 40%→DD35%).
+- *Horizon-set:* every subset (1m/3m/6m/1-3m/3-6m/1-2-4m/2-4-8m) is **positive**; Sharpe 0.37→1.39.
+  Shorter horizons (1m, 1-2-4m) score best (Sharpe 1.34-1.39) — a real plateau, not one combo.
+- *Fee:* survives to 0.40% RT (Sharpe 1.00→0.39, still positive at 4× baseline fee).
+
+**3) The honest caveat — most of the edge is the EARLY regime.**
+Walk-forward split, same param set both assets:
+- **EARLY 2018-2021:** CAGR +26%, Sharpe **1.63**, DD 18%.
+- **LATE 2022-2026:** CAGR +7.3%, Sharpe **0.57**, DD 19%.
+The signal is real and still net-positive every late year, but its quality **halved** post-2021
+(crypto vol compressed, trends choppier). This is the same warning Track A raised, now quantified: the
+edge is strongest 2019-2021 and merely *modest* in the 2022-26 regime.
+
+**4) Leverage is a red herring; target-vol is the real dial — and it costs DD linearly.**
+At tvol=20% on 60-80% crypto vol, positions stay **sub-1x** (avg gross 0.23×): the leverage cap
+**never binds**. To deploy real leverage you raise target-vol; Sharpe stays ~1.0, DD scales:
+
+| target_vol | avg gross | CAGR | Sharpe | maxDD |
+|---|---|---|---|---|
+| 20% | 0.23× | +14% | 1.00 | 19% |
+| 40% | 0.45× | +28% | 1.00 | 35% |
+| 60% | 0.68× | +40% | 1.00 | 48% |
+| 80% | 0.90× | +50% | 1.00 | 60% |
+| 100% | 1.12× | +58% | 0.99 | 69% |
+
+## Verdict — is this a deployable earning system?
+
+**Yes as a risk-adjusted system; NO as a fast path to €50/day on €2000.**
+
+- This is the **first post-reset config that is genuinely robust**: Sharpe ~1.0 (long-flat 1.3),
+  positive every year 2018-2026, robust across grid/horizon/fee, on both assets, on certified data,
+  with honest no-look-ahead accounting. It is a real, deployable trend portfolio and a clear
+  improvement over Track A's lucky single cells. The thesis (DD reduction → leverageable, diversifiable)
+  is **confirmed**.
+- **But the earnings are modest.** Headline (tvol20%, 2x cap, LS): CAGR **+14.2%**, DD 19% ⇒ steady-state
+  **~€0.73/day on €2000**. To average **€50/day at this CAGR you need ~€137k capital**, not €2000.
+- **Leverage can't close the gap cheaply.** Pushing target-vol to 80% gives CAGR ~50% (DD **60%**) — and
+  at €2000, 50%/yr is still only ~€2.7/day in steady state. Reaching €50/day in 1-2 years from €2000
+  would require both heavy leverage (DD 60-70%, near-ruin) **and** lucky path — not a sane plan.
+- **Regime risk:** the edge is much weaker post-2021 (Sharpe 0.57 LATE). Deploy sized for the LATE
+  regime, not the EARLY one.
+
+**Recommendation:** treat this as the **core risk engine** (compounding ~14%/yr at DD<20%, or
+long-flat ~16%/yr at DD 13%), deployable now at low size to validate live execution. It grows €2000,
+but to *€50/day* the lever is **capital + time**, not leverage. Realistic near-term: ~€0.7-1.5/day on
+€2000; €50/day needs ~€70-140k or a second uncorrelated edge stacked on top.

+# 2026-06-19 — Track E: Cross-sectional BTC↔ETH relative-value + ENSEMBLE synthesis
+
+Due parti, entrambe oneste e su dati Deribit-mainnet certificati (solo BTC/ETH). Tool:
+`scripts/research/trackE_xsec_ensemble.py` (runnable, self-contained, riusa il walk-forward
+ML di Track B e il Donchian di Track A). Harness onesto: direzione/posizione decise con dati
+≤ `close[i]`, realizzo sul bar successivo (shift di 1 barra, niente look-ahead). Fee
+turnover-based: `|Δpos|·fee_rt/2` **per gamba** (un flip +1↔−1 = un round-trip = 0.10% RT).
+
+Run: `uv run python scripts/research/trackE_xsec_ensemble.py` (`--quick` salta lo sleeve ML;
+`--no-cache` ricalcola la proba ML). Il proba ML viene cacheato (`.cache_trackE_*.npy`).
+
+---
+
+## PART 1 — Relative value (spread BTC↔ETH, 1h, market-neutral)
+
+**Premessa strutturale.** BTC/ETH log-ret 1h sono correlati **0.84**. Con due soli asset
+l'unica struttura tradabile è lo **spread**. E con due asset, *"long il più forte / short il
+più debole"* (XS-momentum) è **algebraicamente identico** a *"trada il trend del ratio
+ETH/BTC"* — infatti nel codice (A) e (B) producono numeri identici. Sono lo stesso edge.
+
+**Lead-lag: nullo.** `corr(rB[i], rE[i+1]) = −0.018`, `corr(rE[i], rB[i+1]) = −0.007`,
+autocorrelazioni −0.01..−0.02. Nessun potere predittivo cross-asset → lead-lag **non**
+perseguito come sleeve (sarebbe rumore moltiplicato per le fee).
+
+**(A/B) XS momentum / ratio trend (griglia N∈{24,72,168,336}, hold∈{6,24,72}):**
+- Solo **4/12 celle** OOS net-positive, e sparse (N24/h24, N24/h72, N72/h72, N168/h24).
+- Le celle FULL forti (N168/h24: +150% full, Sharpe 0.68, DD 27%) hanno **OOS debole**
+  (+11%, Sh 0.30). La migliore per OOS-Sharpe è N24/h24 (OOS Sh 0.31, OOS net +11%).
+- **Fee sweep (N24/h24):** gross (0bp) FULL +356%/OOS +74% Sh 1.20 → a 1.0bp/gamba FULL +27%/
+  OOS +11% Sh 0.31 → **muore già a 1.5bp/gamba** (OOS −11%). Margine fee sottilissimo.
+- **Per-anno** concentrato sui grandi movimenti del ratio 2020-2021 (e 2024), piatto/negativo
+  altrove (2022 −9%, 2023 −19%, 2025 −6%, 2026 −16%). Non è un altopiano: è un edge debole,
+  fee-sensibile, regime-dipendente.
+
+**(C) Ratio mean-reversion (z-fade di log(ETH/BTC)):** negativa ovunque (es. lb168/zin2.0:
+FULL −85%, OOS −44%, Sh −1.56). Coerente con Track C: anche sullo spread la MR a breve non è
+un edge sul dato pulito.
+
+**Verdetto PART 1:** esiste un **debole** edge di relative-value (XS-momentum ≡ ratio-trend),
+net-positivo OOS solo in alcune celle, Sharpe OOS ~0.3, che **muore a ~1.5bp/gamba** ed è
+concentrato in pochi anni. È **reale ma marginale** — degno di entrare in un ensemble come
+sleeve diversificante, non come strategia standalone. La sua virtù: è **quasi scorrelato**
+dagli edge direzionali (vedi sotto).
+
+---
+
+## PART 2 — Ensemble (3 sleeve residui in UN portafoglio)
+
+Sleeve combinati (gross 1 ciascuno, equal-weight 1/N → gross totale ~1):
+- **S1 = BTC-ML** (Track B, cella onesta a basso turnover W16000 H24 thr0.10, 1h).
+- **S2 = BTC-Trend** (Track A, l'unica cella trend robusta cross-asset: Donchian N=200 H=12).
+- **S3 = Relative-value** (PART 1, miglior cella OOS: XS-momentum N=24 hold=24).
+
+**Finestra comune attiva** (dove tutti e 3 sono live, dopo il warmup ML): 2020-06 → 2026-06,
+52.636 barre.
+
+### Matrice di correlazione degli sleeve (ret per-barra, finestra comune)
+
+|          | S2_trend | S3_relval | S1_ml  |
+|----------|----------|-----------|--------|
+| S2_trend | +1.000   | +0.010    | −0.063 |
+| S3_relval| +0.010   | +1.000    | −0.010 |
+| S1_ml    | −0.063   | −0.010    | +1.000 |
+
+→ **Sleeve quasi perfettamente scorrelati** (|ρ| ≤ 0.06). In teoria, terreno ideale per la
+diversificazione.
+
+### Per-sleeve (finestra comune, scala $ uguale)
+
+| sleeve    | net   | Sharpe | maxDD | €/g(2k) |

+
+### Ensemble
+
+| portafoglio          | net   | Sharpe | maxDD | CAGR  | €/g(2k) |
+|----------------------|-------|--------|-------|-------|---------|
+| best single (S1_ml)  | +382% | +0.87  | 56%   | +30%  | +3.51   |
+| **EQUAL-WEIGHT 1/N** | +109% | **+0.83** | **30%** | +13% | +1.00 |
+| inverse-vol (IS wts) | +76%  | +0.70  | 29%   | +10%  | +0.69   |
+| EQ-WEIGHT **OOS**(65/35)| +32% | **+1.02** | **12%** | +14% | +0.83 |
+
+Per-anno equal-weight: 2020 +16%, 2021 +50%, 2022 +2%, **2023 −13%** (vs −38% dell'ML da
+solo!), 2024 +18%, 2025 +19%, 2026 −3%. **Molto più liscio**, niente anno-catastrofe.
+
+### La diversificazione aiuta? Sì sul rischio, NO sul rendimento risk-adjusted
+
+- **Sharpe:** ensemble 0.83 vs best-single 0.87 → **non batte** il miglior sleeve singolo.
+- **maxDD:** ensemble **30%** vs best-single 56% → **dimezzato**. E OOS 12% vs ML-solo molto
+  più profondo. Per-anno senza il −38% del 2023.
+- **Risk-matched** (levare l'ensemble 1.84x per pareggiare il 56% DD dell'ML): €/g +2.23
+  contro €/g +3.51 dell'ML da solo → a pari drawdown l'ensemble rende **MENO** (ratio 0.64).
+
+**Perché?** Gli sleeve sono scorrelati ma **enormemente diseguali** (Sharpe 0.87 vs 0.15 vs
+0.16). L'equal-weight 1/N "annacqua" l'unico sleeve forte con due deboli: la matematica
+della diversificazione alza lo Sharpe solo se gli sleeve sono di *qualità comparabile*. Qui
+non lo sono, quindi 1/N non può superare il singolo migliore. Pesare verso l'ML (quality-
+weighting) converge banalmente a "esegui solo l'ML" — e sarebbe in-sample.
+
+**Il guadagno vero dell'ensemble è la ROBUSTEZZA, non il rendimento:** stesso Sharpe del
+miglior sleeve a **metà del drawdown**, per-anno molto più stabile, niente dipendenza da un
+singolo modello/regime (l'ML da solo concentra tutto in 2021/2025 con un −38% nel 2023). Per
+chi deve *sopravvivere*, l'ensemble è preferibile; per chi massimizza il rendimento a pari
+rischio, l'ML puro vince di un soffio.
+
+---
+
+## Verdetto onesto — è un motore da €50/giorno? NO.
+
+1. **Relative-value:** edge debole, reale ma marginale (Sharpe OOS ~0.3), fee-sensibile
+   (muore a 1.5bp/gamba), concentrato 2020-2021/2024. Utile **solo** come sleeve scorrelato.
+   Lead-lag e ratio-MR: nulli/negativi.
+2. **Ensemble:** gli sleeve sono **quasi scorrelati** (|ρ|≤0.06) — risultato genuino e bello.
+   L'ensemble equal-weight ottiene **Sharpe ~0.83 a metà del drawdown** del miglior sleeve e
+   un per-anno molto più liscio. **Ma NON alza il tetto risk-adjusted** (a pari DD rende meno
+   dell'ML puro) perché un solo sleeve domina.
+3. **Distanza dal target:** ensemble **€1.00/giorno su €2000** (best single €3.51 ma a DD
+   56% e concentrato). Il target è **€50/giorno → ~50x sotto** (l'ML puro ~14x sotto ma con
+   rischio/concentrazione inaccettabili). Levare per colmare il gap moltiplica il drawdown
+   ben oltre il tollerabile (1.84x già porta al 51% DD per ~€2.2/g).
+
+**Conclusione:** la sintesi di Track E conferma la fotografia dei track A/B/C — esistono
+**edge residui deboli ma reali e scorrelati** su BTC/ETH. Combinarli in un ensemble **migliora
+la robustezza** (DD dimezzato, per-anno stabile, niente single-point-of-failure) ma **non crea
+rendimento dal nulla**: il sistema combinato rende ~€1/giorno su €2000, ~50x sotto l'obiettivo,
+e non è un motore dispiegabile. Il miglior uso pratico dei risultati: se un giorno si tradasse,
+l'ensemble equal-weight (ML + trend + relative-value) è la forma **più onesta e meno fragile**
+del poco edge disponibile — ma serve un edge **di un'altra magnitudine** per avvicinare i €50/g.
+
+## Prossimi passi possibili (non eseguiti)
+- Cercare uno sleeve **di qualità comparabile all'ML** (Sharpe ≥0.5 indipendente) — solo
+  allora 1/N alzerebbe lo Sharpe oltre il singolo. Senza, l'ensemble resta solo "risk smoother".
+- Relative-value su **timeframe diversi** del ratio (giornaliero?) o con **position sizing**
+  proporzionale alla forza del segnale, restando scettici sul fee-margin sottile.
+- Non aumentare la leva per inseguire €50/g: il DD esplode prima del rendimento.
+
+## Artefatti

-
-Dopo che l'intera libreria precedente si è rivelata artefatto di feed/harness disonesti,
-la prima cosa di cui fidarsi NON è una strategia ma il banco di prova. Questo modulo è
-quel banco: causale per costruzione, netto fee, con baseline e null model.
-
-MODELLO CANONICO = SERIE DI POSIZIONE.
-  Una strategia è una funzione  signal(df, **params) -> pd.Series/np.array  che dà la
-  posizione target per barra in [-1, +1]. REGOLA: position[i] è decisa con dati FINO a
-  close[i] (mai oltre) e GUADAGNA il rendimento close[i] -> close[i+1]. L'engine moltiplica
-  position[i] * fwd[i] (fwd strettamente futuro rispetto alla decisione) -> niente look-ahead
-  per costruzione, e niente fill sull'estremo di candela (si entra al close). La fee è
-  addebitata sul TURNOVER |Δposition| (un round-trip 0->1->0 = 2 unità = fee_rt intera).
-
-GATE (vedi CLAUDE.md): ingresso eseguibile (qui per costruzione), netto fee 0.10% RT,

+"""PAPER TRADER — TP01 Trend Portfolio (PORT LF4h), forward-only, simulato.
+
+Esegue la strategia VINCENTE (src/strategies/trend_portfolio.py, config CANONICAL) in
+paper trading FORWARD-ONLY su capitale virtuale (default 2000 USDT), portafoglio 50/50
+BTC+ETH a 4h. Stato persistente -> resume al riavvio.
+
+DESIGN (onesto, niente esecuzione reale: l'esecuzione e' DISABILITATA nel progetto):
+  - Legge i parquet certificati locali (data/raw, BTC/ETH 1h) e resampla a 4h.
+  - Alla prima esecuzione parte dall'ultima barra 4h CHIUSA disponibile (forward-only:
+    NON include lo storico nel PnL di paper, traccia solo da ora in avanti).
+  - Ad ogni run processa le NUOVE barre 4h chiuse dall'ultima volta: applica il rendimento
+    della posizione tenuta, addebita le fee sul turnover, registra i trade sui cambi di
+    posizione, poi ricalcola la posizione-bersaglio (decisa con dati <= ultima barra chiusa).
+  - Per avere barre fresche, aggiornare prima i dati:
+        uv run python scripts/analysis/rebuild_history.py --asset BTC ETH
+
+Stato: data/paper_trend/state.json + trades.jsonl (append-only).
+
+    uv run python scripts/live/paper_trend.py            # avanza il paper col dato disponibile
+    uv run python scripts/live/paper_trend.py --status   # solo stato, non avanza

+"""TRACK B — Machine-learning / feature-prediction on BTC & ETH (Deribit-certified).
+
+Honest, strict walk-forward ML research. The whole point is to NOT repeat the death of
+the old library (look-ahead). Everything here obeys:
+
+  * Features for bar i use ONLY data <= close[i] (all rolling windows are backward).
+  * Labels (sign of forward return over H bars) use close[i+H]; in walk-forward we only
+    train on samples whose label is FULLY realized in the past relative to the prediction
+    bar (a gap of H is enforced between train-end and the prediction block).
+  * Scaler + model are fit ONLY on past data, retrained periodically, never on the future.
+  * Net of fees (fee_rt sweep 0.0005 .. 0.002, baseline 0.001). Turnover reported.
+  * Grid over W (lookback for training), H (horizon), threshold, asset, tf.
+  * A final held-out segment (last HELD_OUT_FRAC) is NEVER used to choose configs;
+    configs are selected on the DEV portion, then confirmed once on the held-out tail.
+
+Run:  uv run python scripts/research/trackB_ml.py
+      uv run python scripts/research/trackB_ml.py --quick      (smaller grid, faster)
+      uv run python scripts/research/trackB_ml.py --gbm        (also try GradientBoosting)
+
+Entry convention (harness): for a signalled bar i we open at close[i] in the predicted
+direction and hold up to H bars (max_bars=H, no TP/SL) — a pure test of directional sign.
+No-overlap is enforced by the harness, so trades are naturally spaced >= H bars.

+"""TRACK C — Mean-reversion / range re-examination on CLEAN BTC/ETH (Deribit mainnet).

+HONEST harness only. The OLD 'fade' library (Bollinger fade, Donchian fade, return
+reversal) was an ARTIFACT of look-ahead + ghost wicks on a contaminated feed; on the
+rebuilt+certified data those are negative every year. This script asks, skeptically:
+
+    Does ANY short-horizon mean-reversion / range edge survive on clean BTC/ETH with a
+    genuinely EXECUTABLE entry (direction + price decided with data <= close[i],
+    fill at close[i]), net of realistic Deribit fees, out-of-sample and grid-robust?
+
+Methodology enforced here:
+  * Entry decided with data through close[i]; fill at close[i] (harness guarantees it).
+    No entering "at the band edge" / candle extreme only known intrabar.
+  * NET fees fee_rt=0.001 baseline + sweep {0.0005, 0.0015, 0.002}.
+  * OOS 65/35 split + parameter grid across BOTH BTC & ETH.
+  * Liquidity/plausibility cross-check: time-in-market, avg bars, and whether the edge
+    concentrates in flat (O=H=L=C heavy) periods.

+"""TRACK D — ROBUST WALK-FORWARD TREND PORTFOLIO (BTC+ETH), vol-targeted + leverage.
+
+Thesis under test: trend-following's real value in crypto is DRAWDOWN REDUCTION vs
+buy & hold (it sidesteps crashes). That lower DD lets us apply LEVERAGE and DIVERSIFY
+across BTC+ETH to build a deployable, risk-adjusted EARNING system, even if each single
+signal has only a modest Sharpe. Question: does a properly-built, anti-overfit trend
+portfolio actually EARN robustly across regimes 2018-2026?
+
+METHOD (strict, honest):
+  * NO LOOK-AHEAD. We build equity directly from a TARGET-POSITION series.
+      - target[i] is decided using ONLY data <= close[i].
+      - target[i] is HELD during the next bar (close[i] -> close[i+1]).
+      - bar return r[t] = close[t]/close[t-1] - 1  (uses close[t], close[t-1]; both <= t).
+      - pnl on bar t = target[t-1] * r[t]            (shift positions by 1 -> no leakage).
+      - fees: fee_per_side * |target[t-1] - target[t-2]| (turnover cost, charged on rebalances).
+    This is the harness's documented "build your own equity from a position series" path.
+  * VOL-TARGETING: position = directional_signal * (target_vol / realized_vol), capped at
+    leverage. realized_vol uses past returns only (rolling std up to close[i]). This is the
+    main lever — it lets a modest signal run at a controlled risk level.
+  * WALK-FORWARD / MULTI-REGIME: per-year returns for ALL years 2018-2026. Plus an explicit
+    EARLY (2018-2021) tune / LATE (2022-2026) confirm split. ONE robust param set, both assets.
+  * PORTFOLIO: equal-weight BTC+ETH sleeves, rebalanced each bar. Report combined Sharpe/DD/CAGR.
+  * GRID ROBUSTNESS: chosen config must be positive across a neighborhood AND across regimes.
+  * FEE & LEVERAGE SWEEP: fee/side 0.0005..0.002 (0.10..0.40% RT); leverage cap 1x..3x.

+"""TRACK E — CROSS-SECTIONAL BTC↔ETH relative-value + ENSEMBLE synthesis.
+
+Two parts, both on certified Deribit-mainnet data (only BTC/ETH), both honest:
+
+PART 1 — RELATIVE VALUE (market-neutral-ish spread trading on TWO assets):
+  * XS relative momentum: go long the stronger asset, short the weaker (dollar-neutral).
+  * ETH/BTC ratio TREND (z-momentum) and ratio MEAN-REVERSION (z-fade of log-ratio).
+  * Lead-lag (descriptive): does BTC's last-bar move predict ETH's next bar (and vice versa)?
+  All positions are decided with data <= close[i] and HELD over the NEXT bar (i->i+1):
+  realized PnL on bar k uses position set at k-1 -> strict 1-bar shift, NO look-ahead.
+  Fees are turnover-based: |Δpos| * fee_rt/2 PER LEG (a +1↔-1 flip = one round trip = fee_rt).
+
+PART 2 — ENSEMBLE:
+  Combine the genuinely-positive residual sleeves into ONE portfolio equity curve:
+    (S1) BTC low-turnover ML momentum (trackB best honest cell: W16000 H24 thr0.10, 1h)
+    (S2) Trend-1h, the only cross-asset-robust trend cell from trackA (Donchian N=200 H=12)
+    (S3) the best relative-value sleeve found in PART 1 (if any net-positive OOS)
+  Report combined Sharpe / maxDD / CAGR / EUR-per-day-on-2000 AND the sleeve correlation
+  matrix. A real ensemble edge must be net-positive OOS and LOWER drawdown than its parts.
+
+Run:  uv run python scripts/research/trackE_xsec_ensemble.py
+      uv run python scripts/research/trackE_xsec_ensemble.py --quick   (skip slow ML sleeve)

+"""HONEST BACKTEST HARNESS — universo certificato BTC/ETH (Deribit mainnet).
+
+Foundation per la ricerca post-reset (2026-06-19). Tutte le strategie nuove devono
+usare QUESTO harness per garantire:
+  1. NESSUN look-ahead: la direzione e il prezzo d'ingresso si decidono con dati fino
+     a close[i] incluso, e si ENTRA a close[i] (la barra successiva, i+1, e' la prima
+     in cui si e' realmente in posizione). L'exit intrabar guarda high/low di i+1..
+  2. Fee realistiche Deribit: 0.10% round-trip (taker) di default.
+  3. Metriche oneste: equity compounding, CAGR, Sharpe (da rendimenti per-barra),
+     max drawdown, per-anno, e split OOS.
+
+Convenzione segnali (entry-eseguibile):
+  Una strategia produce, per ogni indice i, un dict opzionale:
+     {'dir': +1/-1, 'tp': prezzo|None, 'sl': prezzo|None, 'max_bars': int|None}
+  decidendo SOLO con dati [.. i] (close[i] incluso). L'engine apre a close[i] e
+  gestisce l'uscita dalle barre i+1 in poi (TP/SL intrabar al livello, SL prioritario;
+  altrimenti max_bars al close).
+
+Uso tipico:
+    from src.backtest.harness import load, backtest_signals, Metrics
+    df = load("BTC", "1h")
+    entries = my_signal_fn(df)   # list[dict|None] lunga len(df)

+(1-3-6 mesi) vol-targeted, portafoglio 50/50 BTC+ETH. Validata onestamente (no look-ahead,
+fee 0.10% RT, positiva ogni anno 2019-2026, robusta su griglia e su tutti i timeframe 15m-1d).
