🧠 Bayesian Weight Shifts
| Symbol | Top mover | Weight Δ | Lead strategy (conf) |
|---|---|---|---|
| BTC/USDT | walk_forward_ema | -0.254 | post_shock_reversal (61%) |
BTC/USDT (BEAR):
post_shock_reversal is the standout performer with 7d Sharpe of 6.62 and +284 pnl on 63 trades, earning a modest raise toward 0.62 (rule 4), despite its 24h being ugly — the 7d dominates and this is a mean-reversion strategy getting BEAR-regime tail wind from post-shock setups. bollinger is cut from 0.497 to 0.40 because 7d win-rate is only 25% with negative Sharpe and negative pnl (rules 2-3), and in a BEAR regime the band-walk risk is elevated despite the misleading 24h spike. volume_spike is reduced to 0.35 given 7d negative Sharpe and only 36% win-rate on a very large sample (81 trades), confirming persistent underperformance (rules 2-3). walk_forward_ema is raised slightly from 0.612 to 0.52 — wait, it has only 4 trades on 7d (rule 1 low-sample guard) so the weight is nudged down modestly from its elevated 0.612 toward neutral, staying within the +/-0.05 constraint given the thin data; rsi_macd and ema_cross have zero trades across both windows so they are held near their current weights with no data to act on; sentiment shows weak, contradictory signals (only 50% confluence on 7d, mildly positive composite in a BEAR market) so it is nudged slightly down from 0.511; correlation_strategy is silent with zero signals and held at neutral 0.50.
