STRATEGY "Unstable Basket - Stellar Revert Drift-00e7d1 + Mut-6cb7bd + Mut":
TRIGGER:
// Price and volume filters for large-cap, liquid stocks
LAST(CLOSE(sym, 1m)) > min_price
AND ATR(sym, 1d, 9) / LAST(CLOSE(sym, 1d)) > adr_threshold
AND SMA(VOL(sym, 1d), vol_period) > avg_vol_threshold
// Time window: first 174 minutes of session (assuming 10:23-11:00 NY time, adjust to UTC)
AND TIME_UTC_IN("13:37", "15:00")
// Volume pace exhaustion signal on 1m
AND VOL_PACE(sym, 1d, vol_period) > 3
// Short-term reversal signal: price below fast EMA but above slow EMA (mean reversion zone)
AND LAST(CLOSE(sym, 1m)) < EMA(CLOSE(sym, 1m), fast_ema)
AND LAST(CLOSE(sym, 1m)) > EMA(CLOSE(sym, 1m), slow_ema)
// Higher timeframe confirmation (5m trend alignment)
AND EMA(CLOSE(sym, 5m), fast_ema) > EMA(CLOSE(sym, 5m), slow_ema)
ENTRY: MARKET  // Market entry for immediacy on short-term reversal signal
EXIT:
PROFIT_DD_RATIO(CLOSE(sym,1m),20) < 0.7 AND MOMENTUM_QUALITY(CLOSE(sym,1m),8) < 30
RISK: TRAIL_ATR(atr_period, atr_mult)  // Trailing stop based on ATR for dynamic risk control
SIZING: FIXED_FRACTION(risk_frac)  // Fixed fraction sizing for consistent risk exposure
