🧠 Bayesian Weight Shifts

WIF/USDT (SIDEWAYS):

volume_spike is the dominant mover: 7d win-rate of 18% with deeply negative Sharpe (-10.25) and pnl (-496.87) triggers rules 2-3 simultaneously, so I cut it sharply toward 0.13. post_shock_reversal has adequate 7d sample (56 trades) but a sub-30% win-rate (25%) which would normally force a cut, yet its positive Sharpe (1.57) and positive pnl (+68.68) signal the losses are small and winners are meaningful — a mild reduction from 0.48 to 0.40 is the measured response under the conflict rule, favouring data over regime alignment. bollinger gets a modest SIDEWAYS regime nudge upward (only 2 trades so rule 1 caps movement to +/-0.05 of current). sentiment_strategy coverage is sparse (2 sources, 50% confluence, near-neutral composite), so its weight is trimmed slightly toward neutral; all zero-trade strategies are held within +/-0.01 of their current weights per rule 1.

SOL/USDT (SIDEWAYS):

Bollinger is being cut hard from 0.662 despite the SIDEWAYS regime favouring it: 7d win-rate of 26% and Sharpe of -3.03 with -77.47 pnl trigger rules 2 and 3 simultaneously, so it is dropped to 0.35 (conflict rule 6 — data overrides regime prior). tsmom is similarly penalised: 7d win-rate of 17% with Sharpe -3.33 and -82.90 pnl forces a cut toward the floor under rule 2. post_shock_reversal is the standout: 7d Sharpe of 6.52 and +190.92 pnl with 46 trades override the marginal 30% win-rate (rule 3 does not fire on positive Sharpe), and as a mean-reversion family strategy it aligns with the SIDEWAYS regime, so it is raised modestly to 0.62. volume_spike’s 24h Sharpe of 20.02 is a single-day artefact that the 7d window (22% win, Sharpe -1.43, -42.63 pnl) contradicts decisively, so it is cut to 0.25; sentiment_strategy retains moderate trust at 0.58 given 3-source coverage and 67% confluence; all zero-trade strategies are held within ±0.00 of their current weights per rule 1.

SUI/USDT (SIDEWAYS):

Bollinger earns a modest raise from 0.537 to 0.60: it has adequate 7d trade count (13), positive pnl (+214.92), and is perfectly regime-aligned for SIDEWAYS — the extreme Sharpe values are likely artefacts of normalisation on a small sample so they are not taken at face value. volume_spike is cut hard from 0.465 to 0.20 per rules 2-3: 7d win-rate of 23% well below the 30% threshold with negative Sharpe (-3.20) and negative pnl across both windows. walk_forward_ema is cut to 0.15 per rule 3: 7d shows 5 trades with 0% win-rate, deeply negative Sharpe (-12.58), and large negative pnl (-146.40), a clear persistent underperformer. post_shock_reversal is trimmed slightly to 0.55 despite positive 7d pnl (+298.19) because the 24h window is severely negative (win 21%, Sharpe -10.72, pnl -81.80) signalling recent deterioration, while its mean-reversion character still deserves partial SIDEWAYS credit; rsi_macd, ema_cross, tsmom, correlation_strategy, and macro_strategy all have zero 7d trades so rule 1 applies and they are held within ±0.05 of their current weights, and sentiment_strategy is nudged slightly down from 0.460 to 0.44 reflecting only 2 sources with 50% confluence indicating weak signal quality.
