🧠 Bayesian Weight Shifts

SUI/USDT (SIDEWAYS):

rsi_macd, ema_cross, and tsmom have zero trades on both windows so rule 1 applies and they stay near current weight; the SIDEWAYS regime further argues against momentum strategies so they receive no uplift. bollinger has only 4 trades in 7d (rule 1 thin-data guard) but metrics are positive and regime-aligned, yielding a small nudge up from 0.35 to 0.38. volume_spike is cut meaningfully: 7d win-rate of 24% (rule 2 threshold) with negative pnl and a terrible 24h Sharpe of -8.27 both argue for reduction, landing at 0.24. post_shock_reversal is the standout — 43 7d trades, Sharpe ~19.80, +1038 pnl — and as a mean-reversion strategy it fits the SIDEWAYS regime perfectly, so it earns a raise to 0.42 (capped conservatively given extreme Sharpe likely reflects a small denominator and the 20% blending cap). sentiment_strategy is trimmed from 0.451 to 0.38 given low 7d source coverage (3), near-zero avg_composite, and only 33% confluence rate, all indicating weak and unreliable signal; correlation_strategy and macro_strategy have no activity and hold near their current weights.

BTC/USDT (BEAR):

rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero trades in both windows so they are held at their current weights per rule 1 (low-sample guard). bollinger has exactly 5 7d trades (borderline) with a 40% win-rate and positive pnl/Sharpe, earning a small +0.02 nudge; in BEAR it also benefits from the mean-reversion regime boost but the thin sample caps the move. volume_spike has 28 7d trades but a 32% win-rate and negative-leaning direction, so it stays near current with only a modest +0.02 nudge on positive pnl. post_shock_reversal fires rule 2 (17% 7d win-rate) and rule 3 (negative Sharpe and pnl), cut from 0.198 to 0.13; walk_forward_ema has only 2 7d trades but both lost with a severely negative Sharpe (-9.43) and large negative pnl (-75.93), so it is reduced to 0.18 — a cautious cut given the thin data but the signal quality is clearly poor. sentiment_strategy shows good 7d coverage (4 sources), 75% confluence, and near-neutral composite, warranting a hold near its current weight of 0.519.

SOL/USDT (SIDEWAYS):

All price-based strategies except volume_spike and the two empirical losers have zero trades on both windows, so rule 1 holds them near current weight. volume_spike has 76 7d trades but a win-rate of only 33% — well below 55% — so despite positive pnl and an extraordinary Sharpe (likely scale artifact), the persistent sub-30% win-rate triggers a modest cut from 0.677 toward 0.58, with a small SIDEWAYS regime bump partially offsetting the reduction. post_shock_reversal fires rule 2+3 hard: 22% 7d win-rate, Sharpe -3.71, negative pnl — cut to 0.25; walk_forward_ema is even worse (12% win, Sharpe -6.31, -214 pnl) and momentum strategies are disfavoured in SIDEWAYS, so it is cut to 0.10. sentiment_strategy shows decent 7d coverage (4 sources), 75% confluence, and mild positive composite, warranting a small lift to 0.63; correlation and macro have no active signals and stay at current weight.
