🧠 Bayesian Weight Shifts

XRP/USDT (BEAR):

rsi_macd, ema_cross, and walk_forward_ema have zero 7d trades so rule 1 holds them near current weights with no meaningful adjustment. bollinger shows a deeply conflicted signal — strong 7d Sharpe (5.13) and positive pnl (+180.78) but only 32% win-rate and a catastrophic 24h Sharpe (-8.21); per rule 3 the negative win-rate and BEAR regime band-walk risk justify a moderate cut from 0.694 to 0.58 rather than a full raise, respecting the conflict rule. tsmom and post_shock_reversal are both cut: tsmom has only 2 trades with negative Sharpe (-4.41) triggering rules 1 and 3, while post_shock_reversal’s 7d metrics show 25% win-rate and negative Sharpe (-1.55) with negative pnl, hitting rule 2 for a reduction; volume_spike is trimmed modestly as its 29% 7d win-rate (rule 2) offsets the high Sharpe anomaly. sentiment_strategy with 3-source coverage, 67% confluence, and a mildly positive composite is held near its current weight with a small trim to reflect the BEAR regime’s cautious posture toward bullish-leaning sentiment.

BNB/USDT (SIDEWAYS):

rsi_macd, ema_cross, walk_forward_ema, correlation_strategy, and macro_strategy all have zero 7d trades so are held at or near current weight per rule 1. Bollinger shows a strong 7d Sharpe of 6.98 with positive pnl (+173.31) despite a rough 24h, justifying a modest raise in a SIDEWAYS regime where mean reversion is favoured (rule 4 + regime alignment), though the conflicting 24h Sharpe of -2.10 counsels against a large move. post_shock_reversal is deeply penalised — both win rates are below 30% with strongly negative pnl and a catastrophic 24h Sharpe of -32.18, triggering rule 2 cut toward 0.15. tsmom has 7d win_rate of 28% and negative Sharpe in a SIDEWAYS regime where momentum is already disfavoured, so it is trimmed per rules 2-3; volume_spike has a 7d win_rate of exactly 30% with a positive Sharpe (2.66) and positive pnl so it is held near current with only a small reduction for the borderline win-rate. sentiment_strategy is nudged down slightly from 0.526 because confluence at 33% is weak and coverage is only 3 sources, indicating contradictory or sparse sentiment signal.

ETH/USDT (BEAR):

rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero 7d trades so rule 1 locks them within ±0.05 of current weights. Bollinger has only 2 trades but a deeply negative Sharpe (-4.36) and negative pnl in BEAR regime where it already faces a structural headwind, so a modest cut from 0.350 to 0.28 is warranted (rule 3, capped by thin-data caution). volume_spike shows 33 trades with 30% win-rate and a positive 7d Sharpe of 1.52 and positive pnl — borderline rule 2 on win-rate but the positive Sharpe and pnl argue against a hard cut; a small trim from 0.145 to 0.20 reflects its anomalously high 24h Sharpe being noise-driven while acknowledging the marginal 7d performance. walk_forward_ema has 6 trades (just above the rule-1 threshold), 33% win-rate with a very high Sharpe and positive pnl; the low trade count limits confidence so the weight is held near current at 0.40. post_shock_reversal has 33 trades, 27% win-rate (approaching rule 2 threshold) but a strong positive Sharpe and pnl, creating a conflict: the positive risk-adjusted return argues against a hard cut, so a modest trim to 0.30 balances the sub-30% win-rate signal with the positive pnl. sentiment_strategy has weak confluence (33%) and near-zero avg_composite, justifying a small reduction from 0.525 toward neutral at 0.49.
