Expectancy calculation for 13 signal(s) occurring before 08 July 2024 for a 7.5% profit target: (76.92% * 8.88%) + (0% * 0%) - (23.08% * 33.62%) = -0.93%.
Wins: 10 Breakevens: 0 Losses: 3

The Sharpe Ratio calculation assumes a risk free return rate of 2% per calendar year. Ideally the ratio should be a positive number.
