Any possibility to convert a repainting indicator to a non-repainting indicator?

 

2 indicators I encountered that repaint: Fisher and Weiswave3c and I attach them here for your help



Weiswave3c repaint was only found when backtesting on MT4 platform as per the different images below:

first:

earlier chart

then a few bars later:
