Programming question..

 

Hello,


If anyone is familiar with this indicator ( https://www.mql5.com/en/code/7888 ).. I would like to know how to keep track of previous chandlier stop prices...


The example picture provided on the code base shows "Blue for downward support, Red for upward resistance then The current, non-broken blue support";


What do I have to-do to retrieve the value of the last point of the first blue line(point of break) and the last point of the red line(point of break)? I don't necessarily care about the current support/resistance level until it is broken.


Help(if any..) is greatly appreciated
