🧠 Bayesian Weight Shifts

PEPE/USDT (BEAR):

rsi_macd, ema_cross, and tsmom all have zero trades on both windows, so rule 1 holds them at neutral 0.50. Bollinger is an exceptional standout with 7d 75% win-rate, Sharpe of 11.52, and +437 pnl, earning a strong raise per rule 4; although BEAR regimes typically penalise mean-reversion, the data clearly overrides the regime prior (rule 6), and bollinger’s band-walk risk is low given PEPE’s choppy meme-coin price action. volume_spike is a clear conflict case — the 24h metrics look great but the 7d tells the real story: 29% win-rate, Sharpe of -3.58, and -333 pnl, triggering rules 2 and 3 for a sharp cut. walk_forward_ema is the worst performer with 7d 13% win-rate, Sharpe of -14.44, and -1001 pnl, so it is cut hard toward the floor per rule 2. post_shock_reversal shows a modest 7d positive pnl and Sharpe with adequate trade count but a sub-50% win-rate, warranting only a small upward nudge; sentiment is held slightly below its current weight given sparse two-source coverage and only 50% confluence, consistent with the bearish composite reading.

WIF/USDT (BEAR):

walk_forward_ema is the clearest action: 7d win-rate of 22% with Sharpe -8.14 and pnl -460 triggers rules 2-3 hard, so I cut it substantially to 0.20. post_shock_reversal shows strong 7d metrics (41% win, Sharpe 7.26, +583 pnl) and as a mean-reversion strategy is well-suited to BEAR post-shock conditions, earning a raise to 0.58; bollinger similarly benefits from positive 7d Sharpe (4.42) and pnl despite the noisy 24h candle, raised to 0.60 with a small BEAR/mean-reversion regime nudge. rsi_macd, tsmom, and ema_cross all have zero or near-zero 7d trades (rsi_macd/tsmom: 0 trades; ema_cross: 1 trade), triggering rule 1 low-sample guard and holding them near current weight; sentiment_strategy has only 1 source but perfect confluence and a strongly negative composite (-1.00) consistent with the BEAR regime, so it gets a modest nudge down from 0.40 to 0.45 — wait, keeping it near current at 0.45 reflecting the limited single-source coverage per the sentiment guidance.

BNB/USDT (SIDEWAYS):

Bollinger is the clear standout in a SIDEWAYS regime with 7d win-rate of 55%, an exceptional Sharpe of 8.14, and positive pnl of +128.96, earning a significant boost per rules 4 and 5. post_shock_reversal is severely penalised: both 24h and 7d show win-rates well below 30% with deeply negative Sharpe and pnl (-128.92 pnl, -3.72 Sharpe), triggering rule 2’s cut toward 0.10-0.20. volume_spike is cut despite a misleadingly high 24h Sharpe because the dominant 7d window shows 31% win-rate and a negative Sharpe of -1.06 with negative pnl, contradicting the raw headline number (rules 2-3). rsi_macd, ema_cross, and tsmom have zero trades on both windows (rule 1 low-sample guard), so they stay at neutral 0.50; walk_forward_ema gets a marginal haircut on its thin negative 7d Sharpe (rule 1 limits the move); sentiment_strategy earns a modest uplift to 0.55 on strong 100% confluence and consistent two-source coverage, though the deeply negative avg_composite (-0.46) aligns with a cautious SIDEWAYS lean.
