Results show the expected value of your account for the 10th percentile, 25th percentile, 50th percentile, 75th percentile, and 90th percentile. 50th percentile is the average result, 90th percentile would be a great result, and 10th percentile would be a poor result. A percentile is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations fall. For example, the 25th percentile is the value (or score) below which 25 percent of the observations may be found. We run 1000 test simulations (observations) per backtest on your expected values and gather percentile information from these tests.
