🧠 Bayesian Weight Shifts

WIF/USDT (SIDEWAYS):

rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero 7d trades, so rule 1 holds them within +/-0.05 of current. bollinger has only 1 trade with a deeply negative Sharpe (-7.22) and negative pnl, triggering rule 3, but the single-trade sample (rule 1) limits the cut to -0.05 from 0.324 to 0.28; in SIDEWAYS this would normally earn a boost but the data conflict (rule 6) prevents it. walk_forward_ema similarly has 1 trade with a large negative Sharpe (-5.71) and negative pnl, held near its current 0.138 by rule 1 with only a token -0.01 nudge. volume_spike shows a 7d win-rate of only 29% (below 30%) with positive pnl and an elevated Sharpe — the low win-rate triggers a downward pressure per rule 2, but the positive pnl and high Sharpe are contradictory signals suggesting a few large wins masking frequent small losses; the net result is a modest cut to 0.22 rather than the regime-aligned boost. post_shock_reversal has 17 7d trades with positive pnl and a very high Sharpe (9.55) but a win-rate of only 35%, again indicating large-win skew; it earns a small raise to 0.30 on the strength of positive pnl and mean-reversion alignment in SIDEWAYS. sentiment_strategy has only 2 sources with 50% confluence — modest coverage — so it stays near its current 0.464 with no meaningful move.

SOL/USDT (SIDEWAYS):

Bollinger is deeply penalized despite the SIDEWAYS regime: 7d win-rate of 19% and Sharpe of -5.00 with negative pnl triggers rule 2 (persistent underperformance) and rule 3 (negative Sharpe), overriding the regime-alignment nudge and forcing a cut from 0.585 toward 0.30. Volume_spike and tsmom both show severe underperformance (7d win ~17%, Sharpe -4.41 and -3.33, both negative pnl) so they are cut to 0.10 per rules 2-3. post_shock_reversal is the only price-based strategy with positive 7d pnl and a meaningful trade count, but its 7d win-rate of 27% and Sharpe of 0.89 (just below the rule-4 threshold) warrant only a modest reduction from 0.463 to 0.42; sentiment_strategy retains near its current weight on consistent 3-source coverage and 67% confluence. All zero-trade strategies (rsi_macd, ema_cross, walk_forward_ema, correlation_strategy, macro_strategy) are held within ±0.02 of their current weight per the low-sample guard.

SUI/USDT (SIDEWAYS):

volume_spike has 87 7d trades with a 24% win-rate and negative Sharpe (-1.35) and negative pnl, triggering rule 2/3 — cut from 0.423 toward 0.30; post_shock_reversal also underperforms (26% win, negative pnl across both windows) warranting a reduction from 0.487 to 0.38, though the 24h Sharpe distortion is extreme (-15.70) and the 7d Sharpe is only mildly negative so a moderate cut is appropriate rather than a floor cut. bollinger has only 1 7d trade so rule 1 applies — held near current 0.345 with a marginal +0.005 nudge for regime alignment in SIDEWAYS. walk_forward_ema had 1 trade with a sharply negative Sharpe (-9.86) and negative pnl, so trimmed to 0.10; all zero-trade strategies (rsi_macd, ema_cross, tsmom, correlation_strategy, macro_strategy) are held at their current weight per rule 1, and sentiment_strategy is held near current given only modest coverage (2 sources, 50% confluence) with no strong directional signal.
