🧠 Bayesian Weight Shifts

WIF/USDT (SIDEWAYS):

Bollinger is catastrophically underperforming despite a SIDEWAYS regime that should favour it (19% win-rate, -6.51 Sharpe, -432.85 pnl on 47 trades — rule 2+3 fire hard), so I cut it sharply from 0.759 to 0.15; this is a clear conflict-rule 6 case where the data overrides the regime prior. Volume_spike is equally dismal (20% win, -6.00 Sharpe, -452.84 pnl on 55 trades) and gets cut to 0.10 per rules 2-3. Post_shock_reversal shows a deceptive 24h spike but a damning 7d picture (23% win, -3.29 Sharpe, -311 pnl on 65 trades), so it is reduced to 0.20 per rules 2-3; walk_forward_ema similarly has a misleading 24h print but only 9% win over 7d with deeply negative Sharpe, cut to 0.10. Strategies with zero trades (rsi_macd, ema_cross, tsmom, correlation_strategy, macro_strategy) are held at their current weight per rule 1; sentiment_strategy with sparse coverage (2 sources, 50% confluence) gets a small trim to 0.43.

SOL/USDT (SIDEWAYS):

post_shock_reversal is the only clear action item: 7d win_rate of 6% with deeply negative Sharpe (-14.65) and pnl (-305) triggers rules 2 and 3, so I cut it toward 0.10. volume_spike has 72 7d trades with a 36% win-rate — below 50% but still generating large positive pnl (+922) with a high Sharpe (13.78), suggesting a positive-expectancy skew; however the win-rate is below 40% so I modestly reduced it from 0.658 to 0.55 rather than reward it fully, and the SIDEWAYS regime supports keeping it reasonably elevated. bollinger gets a small regime-alignment nudge upward in the SIDEWAYS context despite thin 7d data (4 trades, rule 1 cap applies). sentiment_strategy shows good 7d coverage (4 sources), mild positive composite (+0.09), and solid confluence (75%), warranting a slight trim from 0.659 to 0.66 — essentially held. All zero-trade strategies (rsi_macd, ema_cross, tsmom, correlation_strategy, macro_strategy) have no data and are held near their current weights per rule 1; walk_forward_ema similarly held near its current low weight.

SUI/USDT (SIDEWAYS):

All price-based strategies except post_shock_reversal and walk_forward_ema have zero trades in both windows, so rule 1 applies universally — weights are held within +/-0.05 of current. post_shock_reversal has 71 trades over 7d but win_rate is only 32% (below 30% threshold, rule 2) with an anomalously high Sharpe that suggests a skewed return distribution; as a mean-reversion strategy it has regime alignment in SIDEWAYS, so I apply only a modest cut to 0.55 rather than a deep reduction, balancing rule 2 against regime fit. walk_forward_ema clears the low-sample guard (10 trades, 7d) but 40% win_rate and moderate Sharpe are uninspiring in a SIDEWAYS regime for a momentum-family strategy, so it stays near its current 0.40. sentiment_strategy shows weak coverage (3 sources), low composite (+0.07), and poor confluence (33% on 7d), warranting a small downward nudge to 0.48 per the sentiment weighting rules.
