Expectancy calculation for 2 signal(s) occurring before 28 January 2024 for a 5% profit target: (100% * 5.31%) + (0% * 0%) - (0% * 0%) = 5.31%.
Wins: 2 Breakevens: 0 Losses: 0

The Sharpe Ratio calculation assumes a risk free return rate of 2% per calendar year. Ideally the ratio should be a positive number. A higher positive number indicates the strategy has a more attractive risk adjusted rate of return for this particular buy signal and stock over the chart's timeframe.
