Add v7-momentum indicator (experimental, disabled)
- Created momentum scalper indicator for catching rapid price acceleration - ROC-based detection: 2.0% threshold over 5 bars - Volume confirmation: 2.0x spike (checks last 3 bars) - ADX filter: Requires 12+ minimum directional movement - Anti-chop filter: Blocks signals in dead markets - Debug table: Real-time metric display for troubleshooting Status: Functional but signal quality inferior to v6 HalfTrend Decision: Shelved for now, continue with proven v6 strategy File: docs/guides/MOMENTUM_INDICATOR_V1.pine (239 lines) Lessons learned: - Momentum indicators inherently noisy (40-50% WR expected) - Signals either too early (false breakouts) or too late (miss move) - Volume spike timing issue: Often lags price move by 1-2 bars - Better to optimize proven strategy than add complexity Related: Position Manager duplicate update bug fixed (awaiting verification)

// STRATEGY NOTES
|
||||
// ============================================================================
|
||||
|
||||
// INTENDED USE:
|
||||
// - Complement HalfTrend v6 (catches what trend-following misses)
|
||||
// - Use SMALLER position size (20-30% vs 100% for v6)
|
||||
// - Requires STRICTER quality score (70+ vs 60+ for v6)
|
||||
// - Best on 5-minute timeframe (momentum decays fast)
|
||||
// - ROC 1.5%+ threshold (captures moves before trend confirmation)
|
||||
// - Volume spike lookback (checks current + last 2 bars for confirmation)
|
||||
//
|
||||
// STRENGTHS:
|
||||
// - Catches sharp moves early (first 1-2%)
|
||||
// - High volume confirmation reduces false signals
|
||||
// - RSI directional confirmation (not extremes - allows catching moves earlier)
|
||||
// - Works in volatile markets (where v6 struggles)
|
||||
//
|
||||
// WEAKNESSES:
|
||||
// - More false signals than trend-following
|
||||
// - Requires tight stops (moves reverse quickly)
|
||||
// - Needs active monitoring (not set-and-forget)
|
||||
// - Performance varies by market regime
|
||||
//
|
||||
// QUALITY SCORE IMPACT:
|
||||
// + Volume spike (1.8x+ in last 3 bars): +15 points
|
||||
// + RSI directional (RSI <55 for longs, >45 for shorts): +10 points
|
||||
// + Strong ROC (>1.5%): +10 points
|
||||
// + Strong candle: +5 points
|
||||
// - Weak ADX (<12): -15 points
|
||||
// - Low ATR (<0.25%): -20 points
|
||||
// - Price at extreme (>90% or <10%): -15 points
|
||||
//
|
||||
// Expected score range: 55-85 (vs 60-95 for v6)
|
||||
// Recommended minimum: 70 (vs 60 for v6)
