However, here's an example of how to calculate expectancy:
Formula for Expectancy
Expectancy = (% Won * Average Win) - (% Loss * Average Loss)
Example of Expectancy
If you made ten trades, six of which were winning trades and four of which were losing trades, your percentage win ratio would be 6/10 or 60%.
• If your six trades made $2,400, then your average win would be $400 ($2,400/6).
• If your losses were $1,200, then your average loss would be $300 ($1,200/4).
Expectancy = (% Won * Average Win) - (% Loss * Average Loss)
• Expectancy: (.60 * $400) - (.40 * $300) = $120
In other words, on average, a trader could expect to earn $120 per trade.
