Research Guide

Am I dreaming, or was this new feature just added to backtesting? Thank you for the continuous work on improving the platform!

I gather a limit has been imposed on the number of backtests per strategy. I completely understand the need for this, as I assume the space usage must be crazy. But I wish there was a way to batch remove all backtests, or at least those that resulted in a Runtime Error, as currently this has to be done manually, which is very cumbersome. (The 'Results' window stops refreshing after deleting five backtests, and I have to reload the whole page to continue deleting.) Mea culpa, I suppose: A beginner like myself goes through a massive amount of trial and error attempting to get a strategy running, resulting in dozens of Runtime Errors, and it never occurred to me to delete each one on the fly to save space...

Hi Benjamin,

The number of backtests per strategy is not a hard limit, but just an indicator for when someone might be overfitting their algorithm. More information regarding our research guide is here.

Thanks for your suggestion for the multiple removing feature. We will take it into consideration.
