+"""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
+    uv run python scripts/live/paper_trend.py --reset     # azzera lo stato (riparte da ora)

+
+Vincitrice della ricerca su dati certificati BTC/ETH (Deribit mainnet). TSMOM multi-orizzonte
+(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).
+
+Config canonica deployabile (PORT LF4h):
+    timeframe 4h, LONG-FLAT (niente short), vol-target 20%, leverage cap 2x.
+    -> CAGR ~16.6%, Sharpe ~1.32, maxDD ~12.3% (backtest 2019-2026 su 50/50 BTC+ETH).
+
+Perche' long-flat e 4h: gli short del trend rendono meno e aggiungono DD; il 4h e' il punto
+dolce (meno rumore/fee del 15m, meno lag dell'1d). Vedi docs/diary/2026-06-19-research-synthesis.md
