🧠 Bayesian Weight Shifts

DOGE/USDT (BEAR):

walk_forward_ema is the clearest cut: 7d win=0%, Sharpe=-17.72, pnl=-268.60 — catastrophic across all metrics, so it is dropped near the floor per rules 2-3. bollinger and post_shock_reversal both show persistent underperformance (7d win 20% and 32% respectively, both with deeply negative Sharpe and pnl), earning sharp reductions per rules 2-3; bollinger is also the natural BEAR-regime casualty as a mean-reversion strategy running into a sustained downtrend. volume_spike is the standout exception: despite a noisy 24h window, its 7d record is robust (59 trades, 36% win, Sharpe=3.40, pnl=+171) and it is regime-agnostic, so it earns a modest raise per rule 4. rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero 7d trades and are held at neutral per rule 1; sentiment_strategy is held at its current 0.40 given mild, consistent but not strong coverage (3 sources, 67% confluence, near-neutral composite) with no basis to move it.

PEPE/USDT (BEAR):

walk_forward_ema is the clear outlier: 7d win-rate of 19% with a Sharpe of -11.83 and pnl of -742.34 triggers rules 2 and 3 hard, warranting a deep cut to 0.15 (avoiding the floor given the severity of both pnl and Sharpe). bollinger shows strong 7d metrics (60% win, 7.20 Sharpe, +290 pnl) earning a rule-4 raise, partially tempered by the terrible 24h Sharpe (-15.96) signalling recent regime stress and the BEAR conflict with mean-reversion — net nudge to 0.58. volume_spike has a solid 7d Sharpe (1.91) but a weak 7d win-rate (37%) that falls below the rule-4 threshold, and in a BEAR regime fakeouts are elevated, so a small trim to 0.48 is appropriate; tsmom and post_shock_reversal both show sub-40% 7d win-rates with modest or negative 24h performance, so slight trims apply, while rsi_macd, ema_cross, correlation_strategy, and macro_strategy all have zero trades and are held at neutral per rule 1; sentiment_strategy stays at its current 0.40 given sparse but modestly positive and consistent coverage with no strong directional signal.

XRP/USDT (BEAR):

Bollinger is the standout performer with 7d win_rate 58%, Sharpe 13.42, and +323 pnl, earning a meaningful raise per rule 4; the BEAR regime normally discourages mean-reversion but the data clearly wins here (rule 6 conflict noted — band-walk risk is real, but the numbers are too strong to ignore). Volume_spike has a healthy 7d Sharpe but only 36% win-rate over 47 trades, triggering a modest cut per the sub-40% win signal; post_shock_reversal similarly posts 37% 7d win-rate with modest pnl, warranting a small reduction. rsi_macd, ema_cross, tsmom, and walk_forward_ema all have zero or very thin 7d trades, invoking rule 1 low-sample guard and keeping them near neutral with only a token BEAR-regime nudge downward; sentiment_strategy is nudged slightly down because its mild positive composite (+0.12) conflicts with the BEAR regime and confluence at 75% while coverage is only 4 sources, and correlation_strategy and macro_strategy remain at neutral 0.50 with no actionable signal data.
