🧠 Bayesian Weight Shifts

AVAX/USDT (BEAR):

volume_spike is the clearest action item: 7d win_rate of 22% with Sharpe -2.01 and negative pnl triggers rule 2/3 hard, so I cut it substantially from 0.573 toward 0.25 despite its high trade count. rsi_macd, ema_cross, bollinger, correlation_strategy, and macro_strategy all have zero trades on both windows, so rule 1 applies and weights are held at current levels. tsmom has a curious 7d Sharpe of 3.98 but only 26% win-rate on 23 trades, suggesting a highly skewed return profile; the positive pnl and BEAR regime alignment (momentum family) warrant a small upward nudge to 0.38, but the sub-30% win-rate tempers enthusiasm. post_shock_reversal and walk_forward_ema show similarly anomalous Sharpe figures alongside sub-35% win-rates and positive pnl, so both receive small downward nudges relative to their current weights to reflect the win-rate weakness, while sentiment_strategy is trimmed slightly to 0.50 given only 2 sources and declining weekly confluence from 100% to 50%.

SOL/USDT (SIDEWAYS):

rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero trades across both windows, so rule 1 caps moves within +/-0.05 of current weights; they are held near their current levels. volume_spike has a deeply negative 24h Sharpe (-6.44) and poor 24h win rate (17%), but 7d is positive (Sharpe 1.13, 24% win, +58 pnl); the 7d win rate of 24% nearly triggers rule 2 but falls just short of the <30% persistent threshold — combined with the bad 24h print, a modest trim to 0.30 is warranted, with a small SIDEWAYS regime nudge held back by the weak win rate. post_shock_reversal has a positive 7d pnl and very high Sharpe (2.15) but a 7d win rate of only 32%, suggesting wins are large but inconsistent; it is a mean-reversion strategy well-suited to SIDEWAYS, so I hold it near current at 0.29. walk_forward_ema shows a catastrophic 24h window (0% win, Sharpe -24.55, -105 pnl) which conflicts sharply with a misleadingly high 7d Sharpe (3.25); the 24h data signals recent regime breakdown for this momentum-family strategy in a SIDEWAYS market, so a small trim to 0.32 reflects the conflict rule while not abandoning a 12-trade 7d record; bollinger gets a small SIDEWAYS nudge up from 0.182 to 0.23 despite zero trades, as regime alignment supports it. sentiment_strategy has 3-source coverage, improving 7d confluence (67%), and a mildly positive composite (+0.09), justifying a modest hold near current at 0.58.

BTC/USDT (BEAR):

Most strategies have zero trades in both windows, triggering rule 1 (low-sample guard) and keeping them within +/-0.05 of their current weights. walk_forward_ema is the exception: its 7d window has 5 trades (just above the guard threshold) with 20% win-rate, negative Sharpe (-0.30), and negative pnl (-5.92), plus a catastrophic 24h Sharpe of -42.55, so rule 3 fires and I reduce it by ~0.05 to 0.35. volume_spike has 24 7d trades with only 29% win-rate, but its Sharpe remains positive (0.90) and pnl positive (+16.39), creating a mixed signal — the positive risk-adjusted return prevents a cut under rule 3 but the sub-30% win-rate narrowly avoids rule 2; held near current. sentiment_strategy shows 3-source coverage with weak and slightly contradictory composite signals (near-zero avg, 67% 7d confluence), so I nudge it slightly down from 0.592 to 0.570 rather than hold flat, reflecting modest signal quality without overreacting on a non-price voter.
