Creating Your Edge
Your edge is what makes you profitable over time:
Edge = (Win Rate x Avg Win) - (Loss Rate x Avg Loss)Example:
- 50% win rate
- Avg win: 2R
- Avg loss: 1R
- Edge = (0.5 x 2) - (0.5 x 1) = 0.5R per trade
Backtesting Your System
- Define clear, objective rules
- Test on historical data (min 100 trades)
- Calculate key statistics:
- Win rate
- Profit factor
- Maximum drawdown
- Average R per trade
- Forward test on demo
- Go live with small size
