🧠 Bayesian Weight Shifts

ETH/USDT (BULL):

ema_cross and walk_forward_ema are deeply penalized by rule 2/3 — both show 7d win-rates below 30% and severely negative Sharpes (-7.82 and -6.19) with meaningful negative pnl, so I cut them substantially from their inflated current weights (0.647→0.35, 0.681→0.38), though the BULL regime prevents cutting them to the floor since they are momentum strategies that may recover. volume_spike fires rule 2/3 on 7d metrics (28% win, -1.51 Sharpe, -76 pnl) so it is cut to 0.12 despite a misleadingly good 24h window. bollinger and post_shock_reversal have marginal 7d win-rates near 28-32% and are structurally disfavoured in a BULL regime (band-walk and trend-override risk), so both are nudged down slightly; rsi_macd and tsmom have zero trades and are held at current weight per rule 1. sentiment_strategy shows weak coverage and only 33% confluence across both windows, warranting a small downward nudge from 0.511 toward 0.46; correlation_strategy and macro_strategy also report zero activity and are held at current weight per rule 1.

SUI/USDT (SIDEWAYS):

ema_cross and walk_forward_ema are cut hard: both show 7d win-rates of 28-32% with deeply negative Sharpe (-4.49, -2.34) and large negative pnl, firing rules 2-3 with regime conflict (momentum losing in SIDEWAYS as expected). post_shock_reversal also fires rules 2-3 with 26% win-rate, -2.54 Sharpe, and -186 pnl, pressing it near the floor despite being a mean-reversion strategy in a SIDEWAYS regime — the data overrides the prior (rule 6). tsmom likewise has 26% win-rate and a negative 24h Sharpe, so it is reduced from 0.406. Bollinger is pulled down from its inflated 0.702 current weight because the 24h window is a disaster (17% win, -12.76 Sharpe), though its 7d Sharpe of 1.26 and positive pnl keep it the highest-weighted price strategy per rule 4 and SIDEWAYS regime alignment; volume_spike retains a modest weight on positive 7d Sharpe and pnl with a small SIDEWAYS nudge; sentiment_strategy is held near current on sparse two-source coverage and near-zero composite signal; correlation_strategy and macro_strategy have zero trades across all windows and are held near their current weights per the non-price voter guidance.

SOL/USDT (BULL):

rsi_macd and ema_cross both show 7d win-rates below 33% with negative Sharpe and negative pnl, so both are cut per rules 2-3 despite the BULL regime — the data conflict overrides the momentum prior (rule 6); ema_cross is cut further given its worse 7d Sharpe of -1.55. post_shock_reversal is the worst performer across both windows (29% win, -1.52 Sharpe, -99.73 pnl on 7d, plus catastrophic 24h metrics), so it is cut aggressively toward 0.20 per rule 2. bollinger and volume_spike both show positive 7d pnl and positive Sharpe (4.85 and 4.22 respectively) — unusual for a BULL regime but the data wins — so they receive a modest lift, capped conservatively given the 7d win-rates are still only 34-35%; walk_forward_ema gets a small cut from its marginally negative 7d Sharpe but stays near neutral; tsmom has zero trades (rule 1 thin-data guard, kept within ±0.05 of current); sentiment_strategy shows weak confluence (33%) and near-zero composite across both windows, warranting a small downward nudge; correlation_strategy and macro_strategy both have zero activity and are held near their current weights per the thin-data rule.
