🧠 Bayesian Weight Shifts

WIF/USDT (SIDEWAYS):

volume_spike has zero 7d trades for rsi_macd/ema_cross/tsmom/correlation/macro so those stay near current weights per rule 1; volume_spike shows a catastrophic 7d profile (20% win, -9.47 Sharpe, -890 pnl) overriding the strong 24h fluke, so it is cut hard per rules 2-3 to 0.10. bollinger is the regime-favoured mean-reversion strategy in SIDEWAYS but its 7d win-rate of 23% and brutal 24h Sharpe of -23.60 represent persistent underperformance, so despite regime alignment it is pulled down from 0.828 to 0.55 per rules 2-3 (conflict rule applied: data overrides regime prior). walk_forward_ema has a 7d win-rate of 20% and Sharpe of -4.23 with negative pnl, triggering rules 2-3 for a cut to 0.20; post_shock_reversal’s 7d Sharpe of 3.54 and positive pnl are encouraging but its 7d win-rate of 29% is still below 30% so only a modest reduction from 0.420 to 0.38 is warranted. sentiment_strategy has weak coverage (2 sources, 50% confluence) and near-neutral composite, so it is held close to current weight at 0.40.

XRP/USDT (SIDEWAYS):

Volume_spike is the clearest actionable case: 7d win-rate of 26% (below 30%) with negative Sharpe and negative pnl triggers rule 2/3, so it is cut materially to 0.20. Post_shock_reversal shows a dramatic 24h vs 7d split — the 7d Sharpe of 4.90 and positive pnl are strong, but the catastrophic 24h performance (10% win, Sharpe -37.32, -193 pnl) signals acute recent deterioration; in a SIDEWAYS regime it gets a modest hold near current rather than a full cut, landing at 0.40. Walk_forward_ema has only 1 trade on 7d with negative Sharpe, invoking the low-sample guard (rule 1) and keeping it near its current low weight at 0.18. Rsi_macd, ema_cross, tsmom, bollinger, correlation_strategy, and macro_strategy all have zero trades across both windows, so they are held within ±0.02 of current weights per rule 1; sentiment_strategy’s 7d coverage of 4 sources, 75% confluence, and mild positive composite supports holding it near its elevated current weight at 0.65.

BNB/USDT (SIDEWAYS):

Bollinger’s 7d metrics are contradictory (32% win-rate triggers rule 2 for a cut, but a 9.16 Sharpe and +170.65 pnl signal genuine profitability despite the low win-rate, likely from a few large wins); I hold it near its current weight with a slight trim rather than aggressively cutting, as the SIDEWAYS regime also favours it. Volume_spike is the clearest mover: 7d win-rate of 24% (rule 2) and negative Sharpe and pnl (rule 3) warrant a meaningful reduction from 0.572 toward 0.40. Post_shock_reversal has a 7d win-rate of 29% with negative Sharpe and pnl, so it is cut modestly per rules 2-3, while the deceptive 24h Sharpe spike on only 7 trades is discounted. Sentiment_strategy gets a small bump from 0.575 to 0.60 on good 7d source coverage (4 sources) and strong 7d confluence (75%), slightly offset by a near-neutral composite; all zero-trade strategies (rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, macro_strategy) are held near their current weights per rule 1.
