🧠 Bayesian Weight Shifts

XRP/USDT (SIDEWAYS):

Most strategies have zero trades in both windows (rule 1 low-sample guard), so their weights are held near current with only token nudges; ema_cross and tsmom receive a small -0.01 nudge reflecting the SIDEWAYS regime’s disfavour for momentum, while bollinger gets a marginal +0.03 bump for regime alignment despite zero data. volume_spike is cut from 0.150 to 0.100 under rule 2/3: its 7d record is catastrophic (15% win-rate, Sharpe -12.75, -354 pnl), making this the clearest data-driven reduction. post_shock_reversal is cut from 0.483 to 0.150 under rules 2-3: both windows show win-rates below 25% with deeply negative Sharpe and pnl, representing persistent, severe underperformance that overrides its mean-reversion regime alignment. sentiment_strategy holds near its current weight at 0.520 given stable 3-source coverage and 67% confluence, consistent with the guidance to favour it when coverage and confluence are reasonable.

BNB/USDT (SIDEWAYS):

volume_spike is floored at 0.05 due to catastrophic 7d performance (21% win-rate, Sharpe -16.38, pnl -538) triggering rules 2 and 3 simultaneously; this is the most urgent cut. bollinger earns a boost from its strong 7d Sharpe (2.89) and positive pnl in a SIDEWAYS regime per rules 4 and 5, but is tempered from its extreme current weight of 0.877 because the 24h window collapsed badly (-11.18 Sharpe), so a measured pull-back to 0.72 is warranted. tsmom is nudged down slightly from 0.311 given a 0% 24h win-rate and only marginally positive 7d metrics in a regime that disfavours momentum, while post_shock_reversal and walk_forward_ema hold modest positive adjustments on their positive 7d Sharpe and pnl figures; rsi_macd, correlation_strategy, and macro_strategy have zero trades and are held at or near current weights per rule 1, and sentiment_strategy is nudged slightly down on low 7d confluence (33%) per the sentiment weighting guidance.

WIF/USDT (BEAR):

volume_spike is the clearest action item: 37 trades over 7d with a 16% win-rate, -13.06 Sharpe, and -514 pnl triggers rules 2 and 3 hard, so it is cut to 0.10 near the floor. walk_forward_ema has 27 trades, 22% win-rate, -2.08 Sharpe, and negative pnl, so it is cut meaningfully from 0.501 toward 0.35 per rules 2-3, though the BEAR regime gives it a slight reprieve versus a full collapse since it is a momentum-family strategy in a confirmed downtrend. post_shock_reversal has borderline sample (5 trades) with 20% win-rate and -3.49 Sharpe, applying rule 1 (thin data) but also rule 3 (negative Sharpe), so a modest reduction from 0.187 to 0.14 is warranted. All zero-trade strategies (rsi_macd, bollinger, ema_cross, tsmom, correlation_strategy, macro_strategy) are held within ±0.05 of their current weights per rule 1; sentiment_strategy shows sparse coverage (2 sources, 50% confluence, near-zero composite) so it receives a small downward nudge from 0.416 to 0.38.
