🧠 Bayesian Weight Shifts

BNB/USDT (BULL):

rsi_macd, correlation_strategy, and macro_strategy all have zero trades on both windows (rule 1), so they stay near their current weights with no meaningful adjustment. post_shock_reversal is the standout performer despite being a mean-reversion strategy in a BULL regime — 7d win-rate 69%, Sharpe 24.50, +576 pnl — so I raise it per rule 4 while flagging the regime conflict (rule 6); the data wins. tsmom has strong 7d metrics (59% win, Sharpe 19.19) and is well-aligned with the BULL regime, earning a modest raise from its low current base, capped conservatively given the blending overlay. bollinger and volume_spike both show positive 7d Sharpe and pnl justifying small lifts, though bollinger is regime-misaligned in BULL so its raise is restrained; ema_cross and walk_forward_ema share identical 7d metrics (67% win, Sharpe 18.25) but their 24h Sharpe is deeply negative (-8.22), suggesting recent deterioration, so I raise them only modestly from their low base. Sentiment is near-neutral (avg_composite +0.01, moderate confluence 67%), warranting a slight pull toward 0.50 from its above-neutral current weight.

BTC/USDT (BULL):

rsi_macd has zero trades in both windows so it stays near its current weight per rule 1 (no data to act on). bollinger is the standout non-momentum performer with 7d win=62% and an extraordinary Sharpe of 10.86/pnl=+172, so it earns a meaningful raise despite the BULL regime creating a mild conflict — data wins here (rule 6). ema_cross and walk_forward_ema both show 7d win=29% with deeply negative Sharpe (-3.31) and negative pnl, triggering rule 2/3 cuts toward 0.15; notably their 24h metrics are near-identical, suggesting a systematic issue rather than noise. volume_spike (7d 62% win, Sharpe 25.22, +200 pnl) and tsmom (7d 52% win, Sharpe 17.58, +468 pnl) both earn raises — volume_spike strongly per rule 4 and BULL regime, tsmom modestly as a momentum-family strategy aligned with BULL but with a sub-55% 7d win rate. post_shock_reversal has strong 7d metrics (62% win, Sharpe 14.89) but is mean-reversion family in a BULL regime, so the raise is held to a modest reduction from current rather than an aggressive boost. sentiment_strategy earns a small lift given 3-source coverage with 100% confluence and mildly positive composite. correlation_strategy and macro_strategy both report zero trades/signals across all windows and hold near current weight per rule 1.

XRP/USDT (BULL):

rsi_macd, tsmom, correlation_strategy, and macro_strategy all have zero trades on both windows, so rule 1 applies and weights are held near current levels with no meaningful moves. bollinger shows strong 7d metrics (67% win, Sharpe 24.34, +618 pnl) but is a mean-reversion strategy in a BULL regime where band-walks are a risk; I slightly trim it from 0.669 to 0.65 per the regime conflict rule while acknowledging its genuine outperformance. walk_forward_ema earns a modest lift to 0.35 given 7d 80% win and Sharpe 24.65 with positive pnl, consistent with rule 4 and BULL regime alignment for this momentum-family strategy, though the 7d trade count of 5 sits right at the low-sample threshold warranting caution. sentiment_strategy holds at 0.65 given 3-source coverage with 100% confluence and a mildly positive composite, consistent with its high current weight; post_shock_reversal and volume_spike are nudged slightly down and up respectively reflecting their adequate but not exceptional 7d win-rates against the BULL prior.
