🧠 Bayesian Weight Shifts

ETH/USDT (SIDEWAYS):

rsi_macd, ema_cross, walk_forward_ema, correlation_strategy, and macro_strategy all have zero trades in both windows (rule 1 low-sample guard), so they are held near their current weights with only negligible regime nudges. bollinger gets a modest lift from 0.327 toward 0.38 given its single-trade positive result and SIDEWAYS regime alignment (rule 5), but the 7d sample of 1 trade caps confidence (rule 1). volume_spike is cut from 0.592 toward 0.48 because its 7d win-rate of 28% triggers rule 2 (persistent underperformance) despite the anomalously high intraday Sharpe, which is driven by a small number of lucky candles rather than consistent edge. tsmom is cut to 0.10 for its negative 7d Sharpe of -2.78 and 0% win-rate on thin data (rules 2-3), and post_shock_reversal is trimmed slightly from 0.414 to 0.35 because its 7d win-rate of 27% also breaches the 30% threshold (rule 2), even though its pnl is positive — a signal that a few large wins are masking many losers; sentiment_strategy is held near current at 0.64 given stable 3-source coverage and 67% confluence at a mildly positive composite, consistent with its current above-neutral weight.

BNB/USDT (SIDEWAYS):

rsi_macd, ema_cross, walk_forward_ema, correlation_strategy, and macro_strategy all have zero trades in both windows, so rule 1 applies and weights are held at current levels unchanged. bollinger has 26 trades on 7d with a positive Sharpe (2.85) and positive pnl, but a win-rate of only 31% triggers rule 2 (below 30% threshold is borderline; 31% is just above, so a moderate cut is warranted rather than a deep one) combined with regime alignment in SIDEWAYS — net result is a modest trim from 0.641 to 0.58, acknowledging positive pnl but respecting the low win-rate signal. volume_spike shows 31 trades, 32% win-rate, but a high Sharpe (6.76) and strong pnl (+86.47), suggesting wins are large even if infrequent; in a SIDEWAYS regime it earns a bump per the regime multiplier, raised from 0.188 to 0.35. tsmom has only 4 trades on 7d (rule 1 thin-data guard) and is a momentum strategy disfavoured in SIDEWAYS, so it is held near current at 0.13. post_shock_reversal has abundant trades (73 on 7d) and strong pnl (+251.34) with a high Sharpe (11.55), but a win-rate of 34% means large wins dominate — as a mean-reversion strategy it is regime-aligned in SIDEWAYS and favoured post-shock, so a modest trim from 0.676 to 0.62 acknowledges the low win-rate while preserving its regime and pnl advantage. sentiment_strategy shows 3 sources with 67% confluence on 7d and a mildly positive composite (+0.08), reasonable coverage justifying a near-hold at 0.57 slightly below its current 0.579.

SOL/USDT (SIDEWAYS):

volume_spike is the clearest cut: 60 trades over 7d with only 23% win-rate, negative Sharpe of -1.59, and negative pnl triggers rule 2 (persistent underperformance), dropping it materially from 0.539. tsmom is equally damning — 17% win-rate, Sharpe of -3.33, and -82.90 pnl on adequate 7d sample; rule 2 pushes it toward the floor, tempered by the 20% sanity-blend. post_shock_reversal is the standout performer: 13 7d trades, 62% win-rate, exceptional Sharpe and +401 pnl — rule 4 fires and regime alignment (SIDEWAYS favours mean-reversion) supports a raise to 0.42. rsi_macd, ema_cross, walk_forward_ema, correlation_strategy, and macro_strategy all have zero trades on 7d (rule 1 thin-data guard), so they hold near their current weights; bollinger gets a token SIDEWAYS-alignment nudge but its single 7d trade prevents a larger move; sentiment_strategy has moderate 7d confluence (67%) and 3-source coverage so it holds close to current with a slight trim from 0.628 toward 0.60.
