🧠 Bayesian Weight Shifts

SUI/USDT (BEAR):

The 24h window shows severe negative Sharpe and pnl for all active strategies (bollinger -16.49, volume_spike -23.76, walk_forward_ema -22.80, post_shock_reversal -2.67), signalling a rough recent session, but the 7d window is solidly positive across all four (bollinger 8.86 Sharpe / +347 pnl, volume_spike 10.80 / +620, post_shock_reversal 15.89 / +830, walk_forward_ema 7.79 / +303), so the 7d data dominates per rubric and I anchor on it. In a BEAR regime I favour mean-reversion and volume confirmation, so bollinger and volume_spike earn raises toward 0.65 (7d win-rates of 33-35% are below the rule-4 threshold so I cannot go higher, but positive Sharpe and pnl justify a lift above neutral); post_shock_reversal gets a modest hold near 0.55 given its strong 7d Sharpe but mean-reversion-family caution inside a strong trend; walk_forward_ema is nudged to 0.50 from 0.562 because its 24h collapse and BEAR-regime momentum drag outweigh the positive 7d. All zero-trade strategies (rsi_macd, ema_cross, tsmom, correlation_strategy, macro_strategy) have no data, so rule 1 keeps them within ±0.05 of their current 0.263 weight; sentiment stays near 0.55 given flat neutral composite and thin two-source coverage.

BNB/USDT (BULL):

In a confirmed BULL regime, the momentum strategies dominate: ema_cross (62% win, Sharpe 14.37, +247 pnl 7d) and walk_forward_ema (identical metrics) earn large raises per rule 4 and regime alignment; tsmom (61% win, Sharpe 17.67, +548 pnl) is the top performer and gets the highest momentum weight; volume_spike (47% win but Sharpe 16.99, +517 pnl 7d) is raised on strong risk-adjusted returns despite a brutal 24h drawdown, which is treated as a short-term anomaly against a dominant 7d signal. Bollinger is the clear casualty of band-walking in a trend (33% 7d win, Sharpe -3.82, negative pnl), cut sharply per rules 2-3. post_shock_reversal has a strong 7d record (+448 pnl, 54% win) but is a mean-reversion strategy in a BULL regime with a damaging 24h showing, so it is held near neutral with a modest trim. rsi_macd has fewer than 5 7d trades so rule 1 caps the move to within +0.05 of current, yielding a small nudge up on its positive Sharpe. Sentiment confluence is weak (33% rate, near-zero composite) so sentiment_strategy is trimmed slightly; correlation_strategy and macro_strategy both report zero activity and are held near their current weights per the no-data guidance.

XRP/USDT (BULL):

The 7d window dominates: ema_cross (60% win, 13.88 Sharpe, +491 pnl), volume_spike (47% win, 12.66 Sharpe, +774 pnl), bollinger (46% win, 12.32 Sharpe, +487 pnl), walk_forward_ema (56% win, 12.23 Sharpe, +429 pnl), and post_shock_reversal (44% win, 14.65 Sharpe, +1081 pnl) all show strongly positive 7d risk-adjusted returns, so I nudged each upward modestly; the severe 24h drawdowns on ema_cross, walk_forward_ema, and post_shock_reversal are concerning but do not override the week-long signal — I cap gains to avoid overconfidence. rsi_macd triggers rule 1 (7d trades=5, at the low-sample boundary) so it gets only a small lift from its positive Sharpe and BULL alignment. tsmom has zero trades across both windows (rule 1 hard cap), so I hold it near current with a marginal BULL-regime nudge. Sentiment_strategy has strong coverage and perfect confluence but near-neutral composite (+0.05), so I trim it slightly from its elevated 0.679; correlation_strategy and macro_strategy both show no active signals and remain held near their current low weights.
