Common Issues & Solutions
Issue: Model Win Rate Drops Below 55%
Symptoms: Rolling 100-trade win rate <55% Action:
- Disable model immediately (automatic)
- Review last 20 trades for patterns
- Check if market regime changed (volatility spike?)
- Paper trade for 50 trades before re-enabling
Issue: Drawdown Exceeds 0.5%
Symptoms: Unrealized loss >0.5% on single model Action:
- Alert operations team (automatic)
- Review open positions for correlation
- Tighten stop losses by 20%
- If reaches 1.0%, auto-flatten (kill switch)
Issue: High Correlation Between Models (>0.7)
Symptoms: All models taking same trades Action:
- Calculate correlation matrix daily
- Replace most correlated model with different epoch
- Verify diversification across DQN/PPO and epochs
- Consider reducing Tier 2 allocation temporarily
Issue: Sharpe Ratio Drops Below 2.0
Symptoms: Rolling 50-trade Sharpe <2.0 Action:
- Alert operations team (automatic)
- Review if win rate or hold time changed
- Check for increased volatility (widen stops)
- Consider reducing position size by 50%
Issue: Daily Loss Exceeds -3%
Symptoms: Combined ensemble loss >3% in 24 hours Action:
- Halt all trading immediately (automatic)
- Flatten all open positions
- Conduct post-mortem analysis (data quality? news event?)
- Resume after 24-hour cooling period with half position sizes
Position Sizing
Base Position Size
- Risk per trade: 2% of allocated capital per model
- Stop loss: Dynamic based on ATR (Average True Range)
- Max positions: 3 per model simultaneously
Example (Tier 1 Model with $14K Allocation)
- Per-trade risk: $14K × 2% = $280
- If stop loss = 10 ticks, position size = $280 / 10 = 28 contracts
- Max exposure: 28 contracts × 3 positions = 84 contracts ($2,352 margin)
Scaling Rules
- Win Streak (5+): Increase position size by 20%
- Loss Streak (3+): Decrease position size by 30%
- High Volatility (VIX >25): Decrease position size by 50%
- Low Volatility (VIX <15): Use base position size
Performance Expectations
Conservative (Tier 1 Only, $50K Capital)
- Monthly Return: 26.6% = $13,300/month
- Sharpe Ratio: 8.45
- Win Rate: 60.0%
- Max Drawdown: 0.15%
Balanced (Full Ensemble, $100K Capital)
- Monthly Return: 31.0% = $31,000/month
- Sharpe Ratio: 7.33
- Win Rate: 58.5%
- Max Drawdown: 0.21%
Aggressive (Tier 2 Heavy, $100K Capital)
- Monthly Return: 41.2% = $41,200/month
- Sharpe Ratio: 4.71
- Win Rate: 55.2%
- Max Drawdown: 0.35%
Note: These are backtested projections. Real-world performance will include:
- Transaction costs (2 ticks/trade)
- Slippage (1-3 ticks in fast markets)
- Technology downtime (99.5% target uptime)
- Regime changes (market conditions shift every 3-6 months)
Realistic Expectations: Expect 60-80% of backtested returns in live trading.
