LSTM-Inspired BB Mean Reversion

// ============================================================================
// BOLLINGER BANDS MEAN REVERSION STRATEGY
// Based on LSTM Model True Positive Signal Characteristics
// ============================================================================
// Model learned to identify:
// 1. Price at/below Lower Bollinger Band (100% of TP signals)
// 2. RSI < 30 (Oversold) (75% of TP signals)
// 3. High volatility (wide BB bands)
// 4. Below average volume (contrarian)
