🧠 Bayesian Weight Shifts

ETH/USDT (BEAR):

rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, and macro_strategy all have zero 7d trades, triggering rule 1 (low-sample guard), so they are held at or near current weights. bollinger has only 4 7d trades (rule 1 applies), so despite impressive metrics it is kept at its current 0.35 rather than raised aggressively. volume_spike has a healthy 45 7d trades but a 27% win-rate breaches the rule 2 threshold (< 30%), requiring at least a -0.10 cut from 0.327, landing near 0.30; the strong 24h figures are noted but the 7d win-rate data wins per rule 6. post_shock_reversal’s 7d win-rate is 23% (rule 2) and the 24h window shows 0% wins with deeply negative Sharpe, so a cut from 0.35 toward 0.28 is warranted; sentiment_strategy’s 7d confluence drops to 33% with a near-neutral composite, signalling weak agreement across sources, so it is nudged down slightly from 0.545 to 0.50.

SOL/USDT (SIDEWAYS):

walk_forward_ema is the clearest action item: 7d win-rate of 18% with Sharpe -3.05 and pnl -143.96 triggers rules 2-3 simultaneously, so I cut it meaningfully from 0.363 toward 0.20. post_shock_reversal has a paradox — 26% win-rate triggers rule 2 (cut by ≥0.10) yet its Sharpe is strongly positive (1.95) with positive pnl (+115.58), suggesting a few large wins masking many small losses; the rule-2 cut dominates but I temper it slightly given the positive risk-adjusted return, landing at 0.38 from 0.478. volume_spike has a conflicted profile (7d Sharpe 1.24, positive pnl, but only 23% win-rate), and the 24h window is clearly negative, so I apply a modest cut from 0.376 to 0.32 rather than a boost; bollinger gets only a token nudge downward despite SIDEWAYS regime favouring it because its single 7d trade with negative Sharpe is pure noise (rule 1). rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero trades on both windows and stay within ±0.01 of current; sentiment_strategy is trimmed slightly from 0.581 to 0.56 given weak avg_composite (+0.10) and only moderate confluence (67%) across 3 sources.

BNB/USDT (SIDEWAYS):

All zero-trade strategies have no 7d data (rule 1), so they are held within +/-0.05 of their current weights with only minor nudges toward neutral. walk_forward_ema is the exception: 7d win_rate of 17% with a deeply negative Sharpe of -3.48 and negative pnl (-59.28) triggers rules 2-3, warranting a reduction from 0.366 toward ~0.26. volume_spike has 60 7d trades but a win_rate of only 25% (below the 30% threshold) despite positive pnl and an anomalously high Sharpe, suggesting the pnl is driven by a few large wins masking persistent losses; rule 2 calls for a reduction from 0.526, landing near 0.43 with a SIDEWAYS nudge partially offsetting the cut. sentiment_strategy’s 7d confluence drops to 33% with a near-neutral composite (+0.09), indicating weak agreement across sources, so it is pulled back toward neutral at 0.50 from its current 0.539.
