Developing Your Trading Edge
Without an edge, trading is gambling. Learn to develop, validate, and maintain your edge.
What is a Trading Edge?
Definition
- Statistical advantage over time
- Positive expectancy per trade
- Repeatable and measurable
- Based on market inefficiency
The Expectancy Formula
Expectancy = (Win Rate x Avg Win) - (Loss Rate x Avg Loss)
Example
- Win rate: 55%
- Average win: $100
- Average loss: $60
- Expectancy = (0.55 x 100) - (0.45 x 60) = $28 per trade
