🧠 Bayesian Weight Shifts

WIF/USDT (SIDEWAYS):

post_shock_reversal is the dominant mover: 7d win-rate of 15% and Sharpe of -10.13 with -884 pnl triggers rule 2 (persistent underperformance) and rule 3 (negative risk-adjusted return), so I cut it sharply toward 0.15 — the only strategy warranting a large move given strongly negative data in both windows. Bollinger shows positive 7d pnl and a very high Sharpe, but its 33% win-rate on 43 trades violates the rule-4 threshold (needs >55% win-rate), so despite regime alignment I reduce it modestly from 0.757 toward 0.65 rather than boost it further; the mean-reversion SIDEWAYS nudge partially offsets the win-rate concern. walk_forward_ema has only 9 7d trades (thin data, rule 1) so it receives only a small +0.024 nudge. All zero-trade strategies (rsi_macd, ema_cross, volume_spike, tsmom, correlation_strategy, macro_strategy) are held near their current weights per rule 1; sentiment_strategy sees a minor reduction from 0.504 to 0.48 reflecting weak 7d confluence (50%) and near-zero composite sentiment.

BNB/USDT (SIDEWAYS):

rsi_macd, ema_cross, tsmom, post_shock_reversal, correlation_strategy, and macro_strategy all have zero 7d trades, so rule 1 binds and weights are held at current. bollinger has only 1 trade with a deeply negative Sharpe (-7.22) and negative pnl — rule 1 limits movement to +/-0.05, so I apply a small cut to 0.30 despite the SIDEWAYS regime favoring mean reversion, because the single available data point is negative. walk_forward_ema has exactly 5 trades with 20% win-rate and negative Sharpe (-1.36) and negative pnl, triggering rules 2 and 3 (persistent underperformance + negative risk-adjusted return), warranting a reduction from 0.513 toward 0.42; this also aligns with de-risking a momentum-family strategy in SIDEWAYS. volume_spike has 67 7d trades but only 25% win-rate, breaching rule 2’s 30% threshold, warranting a reduction; however the Sharpe of 4.81 and positive pnl of +183.45 strongly conflict — the low win-rate likely reflects many small losses offset by large wins, and rule 3 does not apply with a positive Sharpe, so I trim only modestly to 0.55 and note the conflict. sentiment_strategy shows weak 7d confluence (33%) with a near-neutral composite, warranting a reduction from 0.564 toward 0.50 per the guidance to lower when sources are contradictory.

SOL/USDT (SIDEWAYS):

rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero 7d trades so rule 1 applies — weights held within ±0.05 of current. bollinger has only 3 trades (rule 1 thin-data guard) but both windows show 0% win-rate and a deeply negative Sharpe (-7.11), so it earns a modest cut from 0.327 toward 0.22, consistent with a SIDEWAYS regime that would normally favour it — the data clearly contradicts that prior (rule 6). volume_spike shows 53 trades on 7d but only 25% win-rate and negative 24h Sharpe, triggering rule 2/3 for a reduction from 0.426 to 0.35; the SIDEWAYS bump is withheld because the underperformance overrides it. post_shock_reversal has 17 trades, 24% win-rate, and negative pnl across both windows, so rule 2 fires and it is cut slightly from 0.217 to 0.18. walk_forward_ema has 16 trades with a positive 7d Sharpe (0.81) and positive pnl (+27.89) but only 19% win-rate, so a full rule-4 boost is not warranted; the 24h single-trade loss is noise (rule 1), and the weight is modestly reduced from 0.511 to 0.46 to reflect the low win-rate. sentiment_strategy shows 3-source coverage, improving 7d confluence at 67%, and neutral-to-mildly-positive composite, justifying a small hold near current weight at 0.62.
