Backtest broken for screen of screens

Since this morning, backtesting a screen of screen gives inconsistent results because stocks are accumulated and never sold.
I use screens of screens for a long time and they were working well without accumuating stocks until yesterday morning.

It seems that it can be fixed, setting the max No parameter. I hope it is correct. I use screens of screens for a long time and it was not necessary before for long-only screens, even screens of screens so clearly something has changed in software behavior. Changes without communication are time consuming and generator of stress for users.

Thank you for reporting this issue. A bug was introduced in the latest codebase, and the fix will be available shortly.
