🧠 Bayesian Weight Shifts

BNB/USDT (SIDEWAYS):

rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, and macro_strategy all have zero 7d trades, triggering rule 1 (low-sample guard) and keeping them at or near current weights. bollinger gets a marginal +0.02 nudge from its single-trade 7d result and SIDEWAYS regime alignment, but the 7d sample of 1 is far too thin to justify a larger move. volume_spike has meaningful 7d volume (65 trades) but a 25% win-rate — well below 30% — triggering rule 2, so it is cut despite its positive pnl and anomalously high Sharpe (likely distorted by the small-loss distribution). post_shock_reversal is penalised heavily: 7d shows 43 trades at 23% win-rate and a deeply negative Sharpe of -4.45 with -107.96 pnl, firing both rules 2 and 3; the flattering 24h Sharpe is a 7-trade sample that cannot override the weekly picture. sentiment_strategy earns a modest +0.01 lift on good 7d source coverage (4 sources) and improved confluence (75%), though the near-zero avg_composite limits any larger boost.

XRP/USDT (SIDEWAYS):

Most strategies have zero trades in both windows, so rule 1 applies universally and weights are held within ±0.05 of current for those; bollinger gets a small SIDEWAYS regime nudge upward from 0.321 to 0.33. walk_forward_ema is the clearest actionable case: 7d win-rate of 14% with a deeply negative Sharpe of -4.58 and pnl of -97.42 triggers rules 2 and 3, so it is cut from 0.395 to 0.22. volume_spike shows a contradictory picture — a toxic 24h Sharpe of -4.10 / 23% win-rate conflicts with a modestly positive 7d Sharpe and pnl, so it is reduced from 0.675 toward 0.55, reflecting the poor recent 24h behaviour while not fully dismissing the 7d positive result. sentiment_strategy has good 7d coverage (4 sources), moderate positive composite (+0.06), and solid 75% confluence, justifying a slight lift to 0.65 consistent with its strong prior weight.

WIF/USDT (SIDEWAYS):

volume_spike is the clearest case: 7d win-rate of 16% with Sharpe -11.98 and PnL -1289.71 triggers rule 2/3 hard, so it is cut sharply toward 0.10. bollinger earns a modest hold near its current high weight as the SIDEWAYS regime favours mean reversion, but its 7d win-rate of only 28% (despite positive PnL and a high Sharpe inflated by the short window) prevents a further raise — rule 2 caution limits confidence even with positive PnL. walk_forward_ema and post_shock_reversal both show negative or near-zero 7d Sharpe with losing PnL, so they are trimmed per rule 3, though not aggressively given the modest magnitude. rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero trades on 7d and are held at their current weights under the low-sample guard (rule 1); sentiment_strategy is nudged only slightly down from 0.431 given sparse coverage (2 sources, 50% confluence) per the sentiment weighting guidance.
