I find a bit odd how the backtest treates the unsufficient data when performing a backtest or a study. It displays an error and encourages the user to go back and set another period - which is rather uneasy as the user needs to calculate the MA period and such.
It would be much easier if the program itself corrected the starting date for the backtest/study for the earliest possible date and displayed a warning with the results.
Thanks for the consideration
