🧠 Bayesian Weight Shifts

BTC/USDT (BULL):

rsi_macd has a 7d win-rate of only 33% and negative 7d Sharpe (-0.65) despite being in a BULL regime, so I cut it per rules 2-3; the conflict between regime and data is named here. ema_cross is the regime-aligned momentum strategy and holds reasonable 7d metrics (37% win, positive pnl, Sharpe 5.87) but its sub-40% win-rate prevents a full boost, so I trimmed modestly from its elevated current weight. walk_forward_ema is cut hard per rule 2 (21% 7d win-rate, negative 7d Sharpe -2.48, negative pnl), while tsmom triggers rule 1 (only 2 7d trades) so it stays within 0.05 of current but also gets a small nudge down for its deeply negative Sharpe. Bollinger gets a modest lift despite the BULL regime because its 7d pnl and Sharpe are the strongest of the price-based strategies; sentiment stays near neutral given low confluence (33% 24h) and near-zero composite; correlation and macro remain unchanged as they report zero activity.

ETH/USDT (BULL):

post_shock_reversal is the clearest cut: 7d win rate of 28% with a deeply negative Sharpe of -12.45 and -461 pnl fires rules 2 and 3 simultaneously, pushing it to the floor at 0.05; bollinger similarly shows a catastrophic 7d Sharpe of -8.43 despite marginally positive 24h metrics, so it is cut near its minimum per rule 3 as expected in a BULL band-walk. volume_spike earns a modest raise to 0.72 on strong 7d fundamentals (42% win, Sharpe 7.52, +374 pnl) despite the noisy 24h session, while ema_cross is nudged up to 0.68 as a BULL-regime momentum strategy with positive 7d Sharpe and pnl even though win rate is below 55%. rsi_macd, tsmom, walk_forward_ema, correlation_strategy, and macro_strategy all have zero 7d trades, so rule 1 keeps them within +/-0.05 of current weights; sentiment_strategy reports good coverage and perfect 100% confluence but a near-neutral composite (+0.03), so it is held slightly below its current 0.638 to reflect the weak directional signal.

BNB/USDT (SIDEWAYS):

rsi_macd shows anomalously high Sharpe values (10.16 on 7d) that are likely an artifact of low volatility or data quirks, but 7d win-rate of 41% is below 50% and pnl is modest, so I trim it slightly from 0.513 toward neutral rather than rewarding the inflated Sharpe; in a SIDEWAYS regime its momentum-leaning nature is a mild liability. bollinger is the expected SIDEWAYS beneficiary but its 7d data is damning — 28% win-rate and a deeply negative Sharpe of -8.91 with -244.79 pnl — a clear band-walk casualty where BNB trended within this ranging label; rule 2+3 force a sharp cut to 0.13. volume_spike is similarly punished by both rules 2 and 3 (29% win, -1.07 Sharpe, negative pnl), with an especially toxic 24h performance (-14.26 Sharpe), so it is cut to 0.13 alongside bollinger. walk_forward_ema retains its weight near current (0.57) as it is the only price-based strategy with positive 7d pnl (+106.92) and a high Sharpe (5.86, noting possible scale artifacts), though 7d trades=10 triggers a mild low-sample caution; sentiment_strategy holds near current (0.62 trimmed slightly to 0.61 rounded) given 100% confluence and consistent coverage across both windows, while tsmom, correlation_strategy, and macro_strategy have zero trades/signals and are held within ±0.05 of their current weights per rule 1.
