🧠 Bayesian Weight Shifts

SOL/USDT (SIDEWAYS):

Bollinger is the most urgent cut: 7d win-rate of 25% and Sharpe of -3.10 with negative pnl triggers rules 2 and 3 hard, and despite the SIDEWAYS regime favouring mean-reversion, the data clearly overrides the prior (rule 6), so I cut it sharply from 0.765 toward 0.20. Tsmom had 0% win-rate on 4 trades with Sharpe -9.20 and -122 pnl, firing rule 2 and pushing it near the floor at 0.10; post_shock_reversal similarly underperforms (26% win, negative Sharpe, negative pnl) so it is trimmed from 0.368 to 0.25. Volume_spike is the only price-based strategy with meaningful positive 7d data (28% win is modest but Sharpe 3.16 and +99 pnl are genuine), and it earns a SIDEWAYS regime bump to 0.35; rsi_macd, ema_cross, walk_forward_ema, correlation_strategy, and macro_strategy all have zero 7d trades so rule 1 applies and they are held near their current weights, while sentiment gets a small trim from 0.611 to 0.58 reflecting weak avg_composite and only moderate confluence.

BNB/USDT (SIDEWAYS):

volume_spike and tsmom are clear underperformers: volume_spike shows 7d win-rate of 19% with a deeply negative Sharpe (-8.23) and negative pnl (-122), and tsmom has 0% win-rate over 6 trades with Sharpe -9.27 and pnl -121, so both are cut toward 0.10 per rules 2-3; tsmom also conflicts with the SIDEWAYS regime as a momentum strategy (rule 6). post_shock_reversal has 69 7d trades at 29% win-rate with positive Sharpe (5.51) and strong pnl (+156), which is borderline on win-rate but the positive risk-adjusted return and mean-reversion nature suit the SIDEWAYS regime, so it is held near current with only a small trim to 0.55. bollinger gets a modest SIDEWAYS regime nudge to 0.35, while sentiment_strategy is nudged slightly to 0.52 on adequate 3-source coverage and 67% confluence; all zero-trade strategies (rsi_macd, ema_cross, walk_forward_ema, correlation_strategy, macro_strategy) are held within ±0.05 of current per rule 1.

SUI/USDT (SIDEWAYS):

Bollinger is the SIDEWAYS regime favourite but its 7d data is damning — 21% win rate, -3.44 Sharpe, -87.62 pnl — so rule 2/3 override the regime prior and I cut it sharply from 0.647 to 0.30. Volume_spike earns a modest lift: despite a weak 7d win rate (30%), its Sharpe is strongly positive (5.60) and pnl is healthy (+309), and it gets a small SIDEWAYS regime bump per rule 5. Post_shock_reversal has a contradictory 24h (22% win, negative Sharpe) but its 7d is anchored by a very high Sharpe (8.86) and large positive pnl (+414), which is the dominant window, so I hold it near current weight at 0.65; walk_forward_ema has marginal 7d metrics (26% win, though Sharpe 1.26 is positive) so I reduce it from 0.670 toward 0.40. All zero-trade strategies (rsi_macd, ema_cross, tsmom, correlation_strategy, macro_strategy) are held within ±0.05 of their current weight per rule 1; sentiment gets a negligible nudge upward given near-neutral, low-confluence coverage.
