As you know, it takes a lot of time and horsepower to run the ECA so it's not practical to automatically re-run everyone's dynamic portfolios backward on-the-fly over periods they didn't test originally. You can always just build a new dynamic portfolio with the same strategies and the same settings, except for an earlier start date. | |
