🧠 Bayesian Weight Shifts

SUI/USDT (BEAR):

rsi_macd, ema_cross, and tsmom all have zero trades on both windows — rule 1 applies strictly and weights are held at current. bollinger has only 2 trades on 7d (rule 1 thin-data guard) so I give only a token +0.005 nudge despite the eye-catching Sharpe. volume_spike shows 88 trades over 7d but a 27% win-rate triggers rule 2 (persistent underperformance), so I cut it from 0.359 toward 0.30 despite the positive pnl, as the low win-rate signals many small losers offset by a few large winners — unreliable in a BEAR regime. post_shock_reversal similarly shows 27% win-rate on 37 trades (rule 2 fires) and although it is mean-reversion-family which gets a BEAR/post-shock nod, the data contradiction overrides the regime prior per rule 6, so I cut it from 0.350 to 0.30. walk_forward_ema is the clearest case: 22% win-rate on 23 trades with negative Sharpe (-2.52) and negative pnl (-98.96) across both windows — rules 2 and 3 both fire, cutting it from 0.533 toward 0.38 (a meaningful reduction constrained by the smoothness rule). sentiment_strategy has only 2 sources with declining confluence (100% 24h vs 50% 7d) and a near-zero composite, so a small downward nudge to 0.46 is warranted. correlation_strategy and macro_strategy have no signal data and are held at current.

SOL/USDT (BEAR):

rsi_macd, bollinger, 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 within ±0.05 of current. volume_spike has a meaningful 7d sample (36 trades) but a poor 25% win-rate triggering rule 2, so it is nudged down modestly from 0.171 to 0.20 — still low but not cut further since it is regime-agnostic. tsmom shows a positive 7d Sharpe (3.90) and positive pnl in a BEAR regime, which is consistent with momentum working in a confirmed downtrend, so it is held at its current 0.452. post_shock_reversal is held at 0.35 despite a sharply negative 24h Sharpe (-26.49) because its 7d window (29 trades, 31% win, positive Sharpe 2.18, positive pnl) is more statistically reliable and the 24h observation is a single-trade outlier. sentiment_strategy has 3-source coverage with 67% 7d confluence and a mildly positive composite (+0.10), which is adequate but not strong, so it is trimmed slightly from 0.638 to 0.60.

AVAX/USDT (BEAR):

rsi_macd, ema_cross, bollinger, correlation_strategy, and macro_strategy all have zero trades across both windows, so rule 1 applies and weights are held at current. volume_spike has sufficient 7d data (75 trades) but a poor 24% win-rate triggering rule 2 (persistent underperformance), so it is cut toward 0.22 despite the misleadingly high 24h Sharpe driven by a tiny pnl on few recent trades. tsmom shows 27 7d trades at 30% win-rate with a positive pnl of 250.63; the win-rate is below 35% which is a weak signal in a BEAR regime where momentum still has some edge, so a modest trim from 0.438 to 0.40 reflects the poor win-rate while respecting the positive pnl and regime alignment. post_shock_reversal and walk_forward_ema both suffered sharp 24h losses (negative Sharpe around -10) but have positive 7d metrics; the 24h pain is noted but 7d dominates per the rubric, so both are held near current with only marginal adjustments. sentiment_strategy has only 2 sources and 7d confluence dropped to 50% with a near-zero composite, indicating weakening signal quality, so it is trimmed slightly from 0.607 to 0.58 per the guidance to lower it when sources are sparse or contradictory.
