🧠 Bayesian Weight Shifts

ETH/USDT (SIDEWAYS):

All zero-trade strategies (rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, macro_strategy) have no data and are held near their current weights per rule 1; walk_forward_ema has only 1 trade on 7d so despite the extraordinary Sharpe/pnl it is statistically meaningless and kept near current. volume_spike shows a conflicted picture: 7d win-rate of 26% (below 30%) would normally trigger a cut, but its 7d Sharpe of 3.70 and positive pnl of +174.81 indicate the wins, though infrequent, are large — the catastrophic 24h window (7% win, Sharpe -21.87) is very short-term noise against an otherwise positive 7d; balancing these, I apply a moderate cut from 0.582 to 0.52 acknowledging the persistent sub-30% win-rate while not ignoring the positive risk-adjusted 7d return. post_shock_reversal is cut from 0.538 to 0.42 because both 24h and 7d win-rates are well below 30% with negative pnl on 7d, firing rule 2/3, though the 7d pnl is only marginally negative so a full collapse is unwarranted; in SIDEWAYS this mean-reversion strategy gets slight regime support but the poor win-rate dominates. sentiment_strategy has consistent 3-source coverage and 67% confluence at a mildly positive composite, warranting a small hold near its current elevated weight with a negligible trim to 0.64.

SOL/USDT (SIDEWAYS):

Bollinger has 55 trades over 7d with an exceptional Sharpe of 7.11 and +294 pnl, but its win-rate of 31% triggers rule 2 (persistent underperformance below 30% threshold is borderline here at 31%), so rather than cutting I moderate it down from 0.817 toward 0.75 — the positive pnl and strong Sharpe indicate the wins are large relative to losses, and SIDEWAYS regime alignment supports keeping it elevated. Volume_spike is cut sharply per rules 2-3: 24% 7d win-rate, Sharpe of -3.61, and -156 pnl represent persistent, risk-adjusted losses warranting a reduction to 0.25. Post_shock_reversal has only 3 trades on 7d but all three lost with a Sharpe of -14.82 and -55.73 pnl; rule 1 limits the move to within +/-0.05 of current, so it is nudged down to 0.10. Sentiment_strategy is trimmed slightly from 0.625 to 0.60 given only 3 sources and modest confluence at 67% with a near-neutral composite, while all zero-trade strategies are held at their current weights per rule 1.

XRP/USDT (SIDEWAYS):

Most price-based strategies have zero trades in both windows (rule 1 thin-data guard), so rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy are held near their current weights with only minor nudges for SIDEWAYS regime alignment. Volume_spike has 32 7d trades with a 25% win-rate and negative Sharpe (-1.71) and negative pnl (-61.67), triggering rule 2/3 persistent underperformance, so it is cut from 0.145 toward 0.10. Post_shock_reversal has strong 7d fundamentals (69 trades, +489 pnl, Sharpe 10.17) which favours a raise under rule 4 and SIDEWAYS/mean-reversion regime alignment, but the catastrophic 24h window (0% win, Sharpe -29.36, -106 pnl) signals a very recent deterioration that warrants caution under rule 6, so it is held nearly flat at 0.65. Sentiment_strategy shows moderate 3-source coverage at 67% confluence with a near-neutral composite (+0.08), warranting a small trim from 0.657 to 0.64; walk_forward_ema has only 1 7d trade with a deeply negative Sharpe (-11.58), so it is trimmed slightly per rule 3 while remaining near its current weight given thin data.
