🧠 Bayesian Weight Shifts

SUI/USDT (SIDEWAYS):

volume_spike is the clear standout loser: 49 trades with only 16% win-rate, Sharpe of -8.37, and -340.91 pnl on 7d — rule 2 and 3 both fire hard, cutting it to the floor at 0.05. post_shock_reversal has 65 7d trades with positive pnl (+641) and a sky-high Sharpe, but only 34% win-rate keeps a full rule-4 boost off the table; the SIDEWAYS regime and mean-reversion family membership justify holding it near current but trimming slightly to 0.55 given the sub-50% win-rate concern. walk_forward_ema shows 24% win-rate on 21 trades — rule 2 fires (below 30%), so I cut it meaningfully from 0.577 to 0.40 despite the oddly positive Sharpe, which likely reflects a few large wins masking persistent losses. rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero 7d trades (rule 1), so they hold within ±0.05 of their current 0.263; bollinger has only 1 trade so stays near 0.329; sentiment_strategy has sparse, contradictory coverage (50% confluence) so it retreats slightly toward neutral at 0.50.

BNB/USDT (SIDEWAYS):

Volume_spike is the clearest action item: 7d win_rate of 22% with a deeply negative Sharpe of -4.03 and pnl of -125.19 triggers rule 2/3, so it is cut sharply from 0.431 to 0.15. Bollinger has a conflicted signal — 7d Sharpe of 2.53 and positive pnl of 64.35 look strong, but a 7d win_rate of only 27% (below the rule-2 threshold) and a severely negative 24h Sharpe of -1.98 suggest the positive pnl is driven by a few large wins masking frequent losses; given SIDEWAYS regime alignment I hold it elevated but trim from 0.784 to 0.65 rather than reward it fully. Sentiment_strategy is nudged down slightly from 0.550 to 0.48 because confluence is only 33% across both windows, indicating contradictory sources that reduce its reliability per the sentiment weighting rules. All zero-trade strategies (rsi_macd, ema_cross, tsmom, walk_forward_ema, correlation_strategy, macro_strategy) are kept near their current weights per rule 1; post_shock_reversal, a mean-reversion strategy modestly suited to SIDEWAYS, is held near its current depressed weight of 0.111 with a minimal trim to 0.13 given no trade data to act on.

ETH/USDT (SIDEWAYS):

Most strategies have zero trades across both windows, triggering rule 1 (low-sample guard) and keeping them within ±0.05 of their current weights; bollinger gets a small +0.01 SIDEWAYS regime nudge despite no trades. Volume_spike has 68 trades on 7d with a 31% win-rate (below the 30% threshold) and positive pnl driven by a high Sharpe — the win-rate borderline triggers a modest reduction to 0.48 rather than a hard cut, as the Sharpe and pnl are strongly positive. Post_shock_reversal shows a mean-reversion profile that fits SIDEWAYS, but its 7d win-rate is also ~30% with borderline negative rule-2 pressure, so it is trimmed slightly to 0.33. Sentiment_strategy has consistent 3-source coverage and 67% confluence at a mildly bullish composite, which is adequate but not exceptional, so it is nudged down marginally to 0.65 to reflect the modest signal strength without a large move.
