Phase 1 Implementation Summary

✅ Completed Features

1. Price Reaction Tracking

File: backend/python_service/services/price_reaction_tracker.py

What it does:

• Tracks price movement 5, 15, and 30 minutes after a signal appears
• Calculates price reaction percentages
• Detects high/low breaks
• Flags if flow led to actual price movement (filters hedges/rolls)

New Fields Added:

• price_reaction_5m_pct - Price change 5 minutes after signal (%)
• price_reaction_15m_pct - Price change 15 minutes after signal (%)
• price_reaction_30m_pct - Price change 30 minutes after signal (%)
• high_break_5m - Boolean: did price break high within 5m?
• low_break_5m - Boolean: did price break low within 5m?
• flow_led_to_move - Boolean: did flow lead to >0.5% price move?

Integration: Called in main.py after price enrichment

2. VWAP Integration

File: backend/python_service/services/price_context.py (extended)

What it does:

• Calculates VWAP (Volume Weighted Average Price) for each trading day
• VWAP = SUM(price * volume) / SUM(volume) from RTH open (9:30 AM) to signal time
• Calculates distance from VWAP for entry/exit logic

New Fields Added:

• vwap_at_signal - VWAP value at signal time
• price_vs_vwap_pct - Percentage distance from VWAP

Integration: Integrated into enrich_flow_with_prices() method

Usage:

• Entry: VWAP pullback or VWAP reclaim
• Exit: Price rejection of VWAP
• Filter: Price too extended from VWAP (>2%) = wait for pullback

---

3. Signal Tier Classification

File: backend/python_service/services/signal_tier_classifier.py

What it does:

• Classifies signals into Tier-1, Tier-2, or Ignore
• Tier-1: 🟢/🔴 + 💎 + ⭐ + premium > 500K + direction aligned (tradeable alone)
• Tier-2: 🟢 + 💎 (no ⭐) OR ⭐ without 💎 (needs confirmation)
• Ignore: OTM-only, mixed signals, low volume/OI ratio

New Fields Added:

• signal_tier - 'TIER_1', 'TIER_2', or 'IGNORE'
• is_tradeable - Boolean: True for Tier-1 only

Integration: Called in main.py after rocket score calculation

Filtering Logic:

• OTM-only prints → Ignore
• Mixed 🟢/🔴 with no net premium edge → Ignore
• Big premium but volume << OI (likely rolls/hedges) → Ignore

---

4. Trade Checklist

File: backend/python_service/services/trade_checklist.py

What it does:

• Evaluates signals against 5-point checklist
• Requires 4/5 checks to pass
• Prevents bad trades

Checklist Items:

1. ✅ Has direction (🟢 or 🔴)
2. ✅ Has diamond (💎)
3. ✅ Has star (⭐)
4. ✅ Price respects VWAP (within ±2%, or ±1% for direction)
5. ✅ Index confirms (placeholder - will be added in Phase 2)

New Fields Added:

• checklist_score - Score out of 5 (0-5)
• checklist_passed - Boolean: True if score >= 4
• checklist_details - Dict with individual check results

Integration: Called in main.py after price reaction tracking

Usage:

• Only trade signals with checklist_passed = True
• Review checklist_details to see which checks passed/failed

API Response

---

🔍 New API Response Fields

All new fields are automatically included in the API response. Key fields to use:

For Filtering:

• signal_tier - Filter to 'TIER_1' for best signals
• is_tradeable - Boolean flag for tradeable signals
• checklist_passed - Boolean flag for checklist-passed signals
• flow_led_to_move - Boolean flag for signals that moved price

For Entry/Exit:

• vwap_at_signal - VWAP value for entry logic
• price_vs_vwap_pct - Distance from VWAP
• price_reaction_5m_pct - Price reaction after signal

For Analysis:

• checklist_score - Checklist score (0-5)
• checklist_details - Detailed check results (JSON)

---

🎯 Usage Examples

Filter to Tier-1 Signals Only:

# In your frontend or API consumer:
filtered = [row for row in data if row.get('signal_tier') == 'TIER_1']

Filter to Checklist-Passed Signals:

filtered = [row for row in data if row.get('checklist_passed') == True]

Filter to Signals That Led to Price Moves:

filtered = [row for row in data if row.get('flow_led_to_move') == True]

Combined Filter (Best Signals):

best_signals = [
    row for row in data 
    if row.get('signal_tier') == 'TIER_1' 
    and row.get('checklist_passed') == True
    and row.get('flow_led_to_move') == True
]

🚀 Next Steps

Immediate:

1. Test the API endpoint to see new fields in response
2. Update frontend to display new fields
3. Add filters for Tier-1 and checklist-passed signals

Phase 2 (Next):

• Strike clustering detection
• Delta weighting
• Index correlation (SPY/QQQ/VIX)

---

📝 Notes

• All new services follow existing code patterns
• No breaking changes to existing functionality
• New fields are optional (won't break if missing)
• Price reaction tracking may be slower for large datasets (batched queries)
• VWAP calculation only works during RTH (9:30 AM - 4:00 PM)

---

🐛 Known Limitations

1. Price Reaction Tracking:

   • Only tracks if price data exists at 5m/15m/30m intervals
   • May be None for signals near market close
   • Uses 0.5% threshold for "flow led to move" (configurable)

2. VWAP Calculation:

   • Only calculated during RTH (9:30 AM - 4:00 PM)
   • Returns None for PRE/POST market signals
   • Requires 1-minute bar data

3. Index Correlation:

   • Currently returns False (placeholder)
   • Will be implemented in Phase 2

4. Checklist:

   • Index confirmation check always fails (Phase 2)
   • VWAP check may fail if VWAP not available (PRE/POST market)
