How to paint past signals when chart loads

[Djinn Trader]

Hey everyone.   Could someone direct me to the function or snipet that draws past buffer signals when the indicator is first loaded onto a chart? Think how Bill Williams fractals paint all previous fractals quite a ways back. I have looked at other indicator code that does paint old signals but I can't see the line that does this. Thanks much in advance.

It is normally done in a loop, so look for the loop in the codes.

Thanks much. I am new to coding and have avoided for loops as long as I can it seems :) I guess it's time to decipher those things haha. Thanks again :)
