🧠 Bayesian Weight Shifts

WIF/USDT (BEAR):

walk_forward_ema has catastrophic 7d metrics (15% win-rate, Sharpe -7.74, -300 pnl) triggering rules 2-3 for a hard cut, but its current weight of 0.601 is high so even after cutting it lands at 0.35 after blending constraints; volume_spike similarly fires rules 2-3 with 23% 7d win-rate, Sharpe -1.06 and 0% win in 24h with extreme negative Sharpe, cut to 0.22. Bollinger had only 1 trade with a deeply negative Sharpe (-7.22) and negative pnl in a BEAR regime where band-walks are a real risk, so it is trimmed slightly per rule 3. rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero trades across both windows — rule 1 applies and weights are held within ±0.05 of current; sentiment_strategy shows sparse coverage (2 sources, 50% confluence) with near-neutral composite signal so it is nudged only modestly downward from 0.417 to 0.38, and post_shock_reversal is left near its already-low current weight as a BEAR regime does not favour mean-reversion entries.

BNB/USDT (SIDEWAYS):

SIDEWAYS regime with strong regime-alignment boost for bollinger, which delivers a dominant 7d Sharpe of 8.82 and +229 pnl despite weak 24h results — raised to 0.75 per rule 4 and regime alignment. volume_spike is catastrophically bad (7d win 26%, Sharpe -10.27, pnl -325) and cut hard to 0.10 per rules 2-3; ema_cross and walk_forward_ema similarly show persistent losses with deeply negative Sharpe and sub-30% win rates so both are cut toward 0.15-0.18 per rules 2-3 and SIDEWAYS conflict. tsmom barely avoids the rule-2 cut on 7d but carries a near-zero negative Sharpe with negative pnl, warranting a modest reduction; post_shock_reversal is regime-suited mean-reversion with positive 7d Sharpe and pnl so it holds near current; rsi_macd’s 7d win rate of 32% is marginal and its high Sharpe is driven by very few 24h trades, so it stays near its current low weight. Sentiment shows low confluence (33%) and near-zero composite signal, warranting a slight reduction; correlation and macro carry no active signals and are held close to current weights.

ETH/USDT (BEAR):

ema_cross is the clearest casualty: 7d win-rate of 18% with a Sharpe of -13.98 and -366 pnl triggers rules 2-3 with a hard cut; volume_spike similarly posts 29% win and -1.40 Sharpe on 69 trades, a large enough sample to justify a significant reduction per rules 2-3. walk_forward_ema has 29% win and a catastrophic -6.54 Sharpe over 24 trades, so it is cut toward the low end per rule 3; post_shock_reversal has 26% win and negative Sharpe over 66 trades, consistent underperformance in a trending BEAR market that punishes mean-reversion, so it is reduced. Bollinger earns a modest raise despite weak 24h results because its 7d Sharpe of 3.53 and +114 pnl over 47 trades is a genuine strong-performer signal (rule 4), and it gains a small BEAR regime mean-reversion nudge; rsi_macd shows marginal 32% win but a positive Sharpe and pnl over 31 trades, so it is held near current with only a small trim; tsmom and sentiment_strategy are held close to current given thin 7d data for tsmom (rule 1) and low confluence/near-neutral sentiment, while correlation_strategy and macro_strategy remain at their low anchors due to zero signals.
