DQN TEMPORAL CHRONOLOGY - QUICK REFERENCE
|
|
==========================================
|
|
Date: 2025-11-04
|
|
Status: ✅ INVESTIGATION COMPLETE
|
|
|
|
CRITICAL FINDING
|
|
-----------------
|
|
ES_FUT_unseen_90d.parquet contains 2024 data (261 days BEFORE training)
|
|
→ TEMPORAL LEAKAGE DETECTED
|
|
→ ALL results from this file are INVALID
|
|
|
|
VALID DATASET
|
|
-------------
|
|
ES_FUT_unseen.parquet (2025-10-20 to 2025-11-03)
|
|
→ Chronologically AFTER training (correct)
|
|
→ Use THIS file for all evaluations
|
|
|
|
TIMELINE

2024-08-04 ──► 2024-11-01 ──► 2025-04-23 ──────► 2025-10-19 ──► 2025-10-20 ──► 2025-11-03

❌ INVALID (90d old) ✅ TRAINING (180d) ✅ VALID EVAL (14d)

MODEL BEHAVIOR (VALID EVAL)

---------------------------
|
|
BUY: 43 (0.3%)
|
|
SELL: 45 (0.3%)
|
|
HOLD: 14332 (99.4%) ← TOO CONSERVATIVE
|

P&L: -$373.25

Sharpe: -7.00
|
|
Win Rate: 19.4%
|
|
Status: ❌ NOT production-ready
|
|
|
|
IMMEDIATE ACTIONS
|
|
-----------------
|
|
1. ✅ Discard ES_FUT_unseen_90d.parquet results
|
|
2. ✅ Use ES_FUT_unseen.parquet only
|
|
3. ❌ DO NOT deploy current DQN model
|
|
4. 🔧 Retrain with diverse regimes + balanced rewards
|
|
|
|
WHY MODEL FAILS
|
|
---------------
|
|
- Trained on single regime (2025 range-bound)
|
|
- Reward function favors HOLD (zero commission)
|
|
- Learned to "do nothing" instead of trade profitably
|
|
- 99.4% HOLD = passive strategy overfitting
|
|
|
|
RETRAINING CHECKLIST
|
|
--------------------
|
|
□ Diverse market regimes (bull, bear, sideways)
|
|
□ Balanced reward (penalize excessive HOLD)
|
|
□ Longer training (365+ days)
|
|
□ Longer evaluation (60-90 days)
|
|
□ Validate temporal chronology (eval > train)
|
|
|
|
VALIDATION COMMAND
|
|
------------------
|
|
# Always verify date ranges before evaluation:
|
|
python3 << 'EOF'
|
|
import pandas as pd
|
|
df_train = pd.read_parquet('test_data/ES_FUT_180d.parquet')
|
|
df_eval = pd.read_parquet('test_data/ES_FUT_unseen.parquet')
|
|
print(f"Training ends: {df_train.index.max()}")
|
|
print(f"Eval starts: {df_eval.index.min()}")
|
|
assert df_eval.index.min() > df_train.index.max(), "TEMPORAL LEAKAGE!"
|
|
EOF
|
|
|
|
CORRECT EVALUATION
