🧠 Bayesian Weight Shifts

XRP/USDT (SIDEWAYS):

Most strategies have zero trades in both windows, so rule 1 (low-sample guard) applies and weights are held within ±0.05 of current; bollinger gets a token +0.02 nudge for SIDEWAYS regime alignment despite no data. post_shock_reversal is the main mover: despite a paradoxically high Sharpe (3.05) its 7d win-rate is only 28% — well below the 30% threshold — triggering rule 2 for a reduction of ~0.08 from its elevated 0.508 current weight, and its mean-reversion nature does suit SIDEWAYS but the persistent sub-30% win-rate in both windows overrides regime alignment per the conflict rule. volume_spike shows a negative 7d win-rate (27%) plus negative 24h Sharpe, so it is trimmed slightly; its 7d Sharpe is anomalously high given the low win-rate, suggesting a few large lucky wins rather than reliable edge. sentiment_strategy is held at 0.633 given consistent 3-source coverage, 67% confluence, and modestly positive composite sentiment, which meets the criteria for maintaining an elevated weight. walk_forward_ema has only 1 trade with a catastrophic Sharpe of -11.58 — thin data prevents a large cut per rule 1 but a small reduction is warranted.

BNB/USDT (SIDEWAYS):

volume_spike is the clear standout loser: 7d win-rate of 22% with a deeply negative Sharpe of -6.19 and pnl of -131.93 triggers rules 2 and 3, cutting it sharply toward 0.10. bollinger is also underperforming in this SIDEWAYS regime (20% win-rate, negative 7d Sharpe, negative pnl), contradicting the usual mean-reversion regime alignment, so the conflict rule applies and it is cut from 0.541 to 0.42 — a meaningful reduction but not a floor cut given it had the most data. rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, and macro_strategy all have zero trades on both windows, triggering the low-sample guard (rule 1) and keeping them within ±0.05 of their current weights. sentiment_strategy shows weak 7d confluence (33%) and a near-neutral composite, so it is nudged slightly down from 0.499 to 0.46; post_shock_reversal is held near its current low weight with a small SIDEWAYS-regime bump given zero data.

ETH/USDT (SIDEWAYS):

volume_spike is the clearest action item: 49 trades over 7d with an 18% win-rate, -5.08 Sharpe, and -197.57 pnl triggers rules 2 and 3 simultaneously, so I cut it sharply toward 0.10. post_shock_reversal shows a dangerously split picture — a spectacular 24h Sharpe of 24.90 on only 5 trades versus a 7d win-rate of 19% and negative Sharpe/-59.63 pnl; the 7d window dominates so I reduce it modestly per rule 3, avoiding a large cut because the 7d sample is borderline (16 trades). walk_forward_ema has only 3 trades in 7d (rule 1 low-sample guard), so despite the eye-catching 5.72 Sharpe I hold it nearly flat at 0.41. All other price-based strategies have zero trades across both windows, making their metrics completely uninformative, so I hold them within ±0.02 of current; sentiment_strategy retains a modestly elevated weight given 3-source coverage and improved 7d confluence of 67%, but I trim it slightly from 0.636 toward 0.62 reflecting only weakly positive and non-confluent signals.
