Integrated MA gap analysis into signal quality evaluation pipeline:
BACKEND SCORING (lib/trading/signal-quality.ts):
- Added maGap?: number parameter to scoreSignalQuality interface
- Implemented convergence/divergence scoring logic:
* LONG: +15pts tight bullish (0-2%), +12pts converging (-2-0%), +8pts early momentum (-5--2%)
* SHORT: +15pts tight bearish (-2-0%), +12pts converging (0-2%), +8pts early momentum (2-5%)
* Penalties: -5pts for misaligned MA structure (>5% wrong direction)
N8N PARSER (workflows/trading/parse_signal_enhanced.json):
- Added MAGAP:([-\d.]+) regex pattern for negative number support
- Extracts maGap from TradingView v9 alert messages
- Returns maGap in parsed output (backward compatible with v8)
- Updated comment to show v9 format
API ENDPOINTS:
- app/api/trading/check-risk/route.ts: Pass maGap to scoreSignalQuality (2 calls)
- app/api/trading/execute/route.ts: Pass maGap to scoreSignalQuality (2 calls)
FULL PIPELINE NOW COMPLETE:
1. TradingView v9 → Generates signal with MAGAP field
2. n8n webhook → Extracts maGap from alert message
3. Backend scoring → Evaluates MA gap convergence (+8 to +15 pts)
4. Quality threshold → Borderline signals (75-85) can reach 91+
5. Execute decision → Only signals scoring ≥91 are executed
MOTIVATION:
Helps borderline quality signals reach execution threshold without overriding
safety rules. Addresses Nov 25 missed opportunity where good signal had MA
convergence but borderline quality score.
TESTING REQUIRED:
- Verify n8n parses MAGAP correctly from v9 alerts
- Confirm backend receives maGap parameter
- Validate MA gap scoring applied to quality calculation
- Monitor first 10-20 v9 signals for scoring accuracy
- Updated .github/copilot-instructions.md key constraints and signal quality system description
- Updated config/trading.ts minimum score from 60 to 81 with v8 performance rationale
- Updated SIGNAL_QUALITY_SETUP_GUIDE.md intro to reflect 81 threshold
- Updated SIGNAL_QUALITY_OPTIMIZATION_ROADMAP.md current system section
- Updated BLOCKED_SIGNALS_TRACKING.md quality score requirements
Context: After v8 Money Line indicator deployed with 0.6% flip threshold,
system achieving 66.7% win rate with average quality score 94.2. Raised
minimum threshold from 60 to 81 to maintain exceptional selectivity.
Current v8 stats: 6 trades, 4 wins, $649.32 profit, 94.2 avg quality
Account growth: $540 → $1,134.92 (110% gain in 2-3 days)
V8 improvements to handle small bounces in strong trends:
- Increased flip threshold: 0.5% → 0.8% (stronger move required)
- Added confirmBars: 2 bars required after threshold breach
- Momentum tracking: Counts consecutive bars in new direction
- Anti-whipsaw: Flip only after 3 consecutive bars (confirmBars+1) beyond threshold
Example: In downtrend, price must close >0.8% above line for 3 bars before flipping bullish
This filters 1-2 bar bounces that don't change the macro trend
Result: Far fewer false reversals during strong directional moves
V8 Changes (fundamental improvements, not just filter toggles):
- Increased ATR multipliers across all timeframes (stickier line)
- Minutes: 3.3→3.8
- Hours: 3.0→3.5
- Daily: 2.8→3.2
- Weekly: 2.5→3.0
- NEW flip threshold (0.5%): Requires price to move beyond line by % before color changes
- Entry buffer enabled by default (0.20 ATR vs 0.15)
- ADX minimum increased to 18 (from 14) for stronger trend requirement
- Core HalfTrend logic modified to require threshold breach before flip
Goal: Reduce flip-flops while maintaining high-quality trend signals
Test against v6 (filtered) and v7 (pure flips) for comparison
