🧠 Bayesian Weight Shifts

SOL/USDT (SIDEWAYS):

Most strategies have zero trades on both windows (rule 1 low-sample guard), so their weights are held near current or nudged only slightly for regime alignment: bollinger gets a small SIDEWAYS bump (+0.014) and tsmom is trimmed modestly (-0.031) as a momentum strategy disfavoured in a ranging market. post_shock_reversal is the clear exception — 7d win_rate of 25% with a deeply negative Sharpe of -1.79 and negative pnl (-81.98) across 36 trades triggers rules 2-3, cutting it from 0.350 to 0.180. volume_spike also has 57 7d trades with a 26% win-rate and negative 24h Sharpe, warranting a meaningful reduction from 0.421 to 0.330 despite its positive 7d pnl. walk_forward_ema has exactly 5 7d trades (borderline rule 1) and the 24h Sharpe of 37.66 is almost certainly a two-trade artefact, so only a small upward nudge to 0.200 is warranted. sentiment_strategy shows moderate confluence (67%) and near-neutral composite, so it is trimmed slightly from 0.601 to 0.580 to reflect the weak signal environment without abandoning the coverage it provides.

BNB/USDT (SIDEWAYS):

post_shock_reversal is the clearest cut: 7d win-rate of 10% with Sharpe -10.25 and pnl -135 triggers rule 2 (both windows negative, persistent underperformance), so it is reduced to the floor at 0.05. Bollinger is the regime-favoured mean-reversion strategy in SIDEWAYS, but its own data contradicts the prior — 7d Sharpe -2.29 and 30% win-rate on 30 trades is genuine underperformance (rule 3/6 conflict), so I cut it meaningfully from 0.626 toward 0.45 rather than raise it. volume_spike has a stark split: the 24h is dreadful but the 7d shows 77 trades, Sharpe 5.79, and +224 pnl, so the large-sample weekly data wins and I hold it near its current weight with a marginal SIDEWAYS bump to 0.65; walk_forward_ema has only 2 trades on 7d (rule 1 low-sample guard), so it moves only modestly from 0.254 to 0.28. All zero-trade strategies (rsi_macd, ema_cross, tsmom, correlation_strategy, macro_strategy) are held at their current weights per rule 1; sentiment_strategy is nudged down slightly from 0.551 to 0.48 reflecting weak 7d confluence of only 33% and a near-neutral composite, reducing its reliability signal.

WIF/USDT (SIDEWAYS):

volume_spike is by far the clearest mover: 64 trades over 7d with only 16% win rate, sharply negative Sharpe (-16.95) and large negative pnl (-1238.91) triggers rule 2/3, cutting it toward 0.10. bollinger has strong pnl and a very high reported Sharpe but its 7d win rate is only 36% — below the 55% threshold for a full rule-4 boost — so I trim it modestly from 0.581 to 0.55 rather than raise it further; the SIDEWAYS regime supports keeping it elevated but the sub-50% win rate warrants slight caution. post_shock_reversal has marginal 7d metrics (30% win, positive Sharpe and pnl on only 10 trades) fitting its mean-reversion character in a SIDEWAYS regime, so it stays near current weight with a tiny nudge up. sentiment_strategy shows only 2 sources with 50% 7d confluence — sparse and contradictory — warranting a small reduction from 0.490; all zero-trade strategies (rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, macro_strategy) have no actionable data and are held at their current weights per rule 1.
