🧠 Bayesian Weight Shifts

AVAX/USDT (BEAR):

walk_forward_ema is the clearest action: 7d shows 0% win-rate, deeply negative Sharpe (-11.51), and -165 pnl on 4 trades — rule 2/3 fires and I cut it to 0.10, just above the floor. bollinger has a puzzling profile (25% win-rate breaches rule 2 threshold) but its 7d Sharpe of 1.80 and positive pnl of +48 suggest profits are concentrated; in a BEAR regime mean-reversion is out-of-favour so I trim it from 0.589 to 0.45 rather than raise it, respecting both the low win-rate and the regime conflict. volume_spike and post_shock_reversal both show extreme 24h distress (sharpes of -7 and -14) but their 7d metrics are strongly positive (Sharpe 10.16/14.19, pnl +630/+900); the 24h window is treated as noise per the rubric’s 7d dominance rule, so I hold volume_spike near current and nudge post_shock_reversal slightly down from 0.644 to 0.55 given its mean-reversion nature conflicting with the BEAR trend. sentiment_strategy has 3-source coverage with 100% confluence both windows, supporting a near-current weight of 0.62; all zero-trade strategies (rsi_macd, ema_cross, tsmom, correlation_strategy, macro_strategy) are held within ±0.05 of their current 0.263 weight per rule 1.

SOL/USDT (BULL):

Bollinger is the standout performer (7d 67% win, Sharpe 14.30, +600 pnl) and earns a raise to 0.82 despite being a mean-reversion strategy in a BULL regime — the data overwhelmingly overrides the regime prior per rule 6. volume_spike has strong 7d metrics (Sharpe 11.82, +629 pnl, 48% win) but its 24h collapse (25% win, Sharpe -22, -203 pnl) is a warning flag, so it is trimmed modestly to 0.68. walk_forward_ema is cut to 0.10 on persistent 7d underperformance (30% win, Sharpe -4.99, -140 pnl per rules 2-3), and post_shock_reversal is trimmed to 0.44 given its 7d win-rate of 39% — a mean-reversion strategy that struggles even in a ranging window warrants caution. rsi_macd sits at borderline 5 trades on 7d with a negative Sharpe so receives only a minor downward nudge; ema_cross and tsmom hold near current weights given zero or thin trade data, with tsmom getting a small BULL-regime momentum nudge; sentiment, correlation, and macro remain near current weights as non-price voters with no new signals to act on.

ETH/USDT (BULL):

volume_spike is the clearest loser: 7d win-rate 29% with negative Sharpe (-1.73) and negative pnl (-89.31), triggering rules 2 and 3 for a meaningful cut from 0.479 to 0.28. rsi_macd also shows persistent underperformance (7d win-rate 33%, below the 30% threshold on rule 2) despite an anomalously high Sharpe that likely reflects very few large winning trades masking a poor hit-rate, so it is reduced from 0.563 to 0.42; ema_cross and walk_forward_ema are trimmed only modestly because 7d win-rates (40%) and positive Sharpes keep them above the cut threshold and the BULL regime gives them a small alignment nudge. post_shock_reversal is the strongest concrete performer (7d 45% win, Sharpe 14.51, +802 pnl) and earns a lift to 0.52 despite being mean-reversion-family in a BULL regime, because the data overrides the regime prior per rule 6; tsmom stays near its current low weight given zero trades (rule 1); sentiment stays near current with a slight trim reflecting only modest confluence (67%) and near-neutral composite; correlation_strategy and macro_strategy both have zero trades and no actionable signal so they hold near their current low weights.
