research(alt): sweep 104 strategie alternative su Deribit (153 agenti) + marginal scorer
Ondata di ricerca onesta a largo spettro su BTC/ETH+DVOL certificati: 104 ipotesi distinte (11 famiglie), un agente-finder per ipotesi, verifica avversariale a 3 scettici sui promettenti, sintesi (153 agenti totali). Esito: NIENTE di nuovo regge -> conferma del soffitto strutturale ~1.3 BTC/ETH-direzionale; lo stack TP01+XS01+VRP01 resta imbattuto. - altlib.py: harness condiviso vettoriale leak-free (eval_weights/study_weights, fee-sweep, both-asset + hold-out 2025+). Riproduce i numeri canonici di TP01. - MARGINAL SCORER (study_marginal/marginal_vs_tp01): Sharpe INCREMENTALE vs baseline TP01 (corr, blend uplift OOS, alpha residua) + jackknife OOS (clean-year + drop-best-month). earns_slot = abs!=FAIL & ADDS & robust_oos. Smaschera gli overlay su TSMOM con PASS assoluti fasulli (CMB04, VOL11, ...) e il falso positivo KAMA (ADDS ma muore al jackknife). - runs/*.py (104) script riproducibili per ipotesi; wf_altstrat.js workflow. - Verdetto: 0 candidati deployabili; 2 LEAD fragili (VOL08, STA05_LS) da forward-monitor. - test_marginal_scorer.py blocca baseline + invarianti. Suite: 32 verde. Diario: docs/diary/2026-06-20-alt-strategies-100agent-sweep.md Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

"""OPT08 — Risk-reversal directional via DVOL-change skew proxy.
|
||||
|
||||
HYPOTHESIS: The 25-delta risk reversal sign can be proxied from DVOL changes.
|
||||
When DVOL rises sharply relative to recent history (puts bid up = skew bullish for
|
||||
downside fear = bearish tilt) we go short; when DVOL falls (fear subsides / calls
|
||||
catching up relative = bullish tilt) we go long. We also test the opposite sign to
|
||||
be honest about direction. We use DVOL z-score over rolling windows as the signal.
|
||||
|
||||
CAVEAT: This is a heavy proxy — DVOL is the ATM vol index, not skew. The actual
|
||||
25d risk reversal is not in the data. Results should be treated as suggestive only.
|
||||
|
||||
DVOL history: starts 2021-03, so ~4 years of data. FULL window covers 2021-2026.
