You don't need to create a second paid strategy. You can modify your existing one at any time to look at 'what if' scenarios, then change it back. You could change your existing strategy from 'Trade > 30 Days' to 'trade any day' take a screen shot of the results, save the screen shot, then change back to 'Trade > 30 Days'. I do this myself. I change the individual stocks in my 'Top S&P 500 sector stocks' every week in the same paid strategy. No additional fees. No harm done. You just cant easily undo the changes you have made with a back button, or un-do button. You have to make the changes back manually.
