🧠 Bayesian Weight Shifts

WIF/USDT (SIDEWAYS):

rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero trades in both windows, so rule 1 applies and weights are held near current. bollinger has only 2 trades but both are losing with a deeply negative Sharpe (-8.01) and negative pnl, so it is cut modestly per rules 1 and 3 (thin data guards against a large cut). volume_spike is the clearest data signal: 44 trades over 7d with positive pnl (+118) and a positive Sharpe (2.39), but a low win-rate of 25% (rule 2 would normally penalise sub-30%, however the positive pnl and Sharpe indicate a few large winners outweigh frequent small losses); in a SIDEWAYS regime volume_spike earns a small regime bump, raising it slightly from 0.165 to 0.28. post_shock_reversal has 63 trades, 30% win-rate (borderline rule 2), but a strong positive Sharpe (4.96) and large positive pnl (+333.50) indicating asymmetric profitable reversals consistent with the SIDEWAYS mean-reversion prior, so it is held near current weight with a modest trim from 0.590 to 0.55 to reflect the low win-rate risk. walk_forward_ema has only 1 trade with negative Sharpe and pnl, so it is held near its current low weight per rule 1. sentiment_strategy has only 2 sources, 50% confluence, and near-zero composite, indicating weak and contradictory signals, so it is trimmed slightly from 0.435 to 0.41.

BNB/USDT (SIDEWAYS):

Bollinger is cut from its inflated 0.78 despite SIDEWAYS regime favour because 7d win_rate of 28% and negative Sharpe (-0.62) with negative pnl triggers rule 2/3 — the band-walk is punishing even in ranging conditions — so it drops to 0.55 (a large cut but justified by persistent underperformance, stopping short of deeper cuts since regime alignment partially mitigates). post_shock_reversal is the standout: 7d Sharpe of 8.40 with +199.89 pnl and 63 trades is a strong rule-4 signal, and as a mean-reversion strategy it aligns with the SIDEWAYS regime, raising it to 0.68 despite the ugly 24h window which is treated as noise relative to the dominant 7d window. volume_spike has a conflicted picture — excellent 7d Sharpe (1.28) and positive pnl but only 25% win-rate, signalling a few large wins masking frequent losses, so it gets a modest trim to 0.48 rather than a SIDEWAYS bump. All zero-trade strategies (rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, macro_strategy) are held within +/-0.05 of current per rule 1; sentiment is nudged down slightly to 0.46 reflecting weak confluence (50%) and near-zero composite sentiment offering little directional signal.

SOL/USDT (SIDEWAYS):

Almost every price-based strategy has zero 7d trades, triggering rule 1 (low-sample guard) and keeping all such weights within +/-0.05 of their current values. Bollinger gets a marginal +0.02 nudge reflecting its single profitable 7d trade and SIDEWAYS regime alignment, but the sample of 1 is far too thin for a larger move. post_shock_reversal has 12 7d trades with a 25% win-rate, breaching the rule-2 threshold for persistent underperformance, so it is trimmed slightly from 0.199 to 0.17; the 24h Sharpe spike is noise given the conflicting 7d picture. sentiment_strategy holds near its current 0.613 — four sources with 75% confluence and a mildly positive composite are consistent with its prior reading, warranting no meaningful change.
