The point was to automate it from AFL... or course it's easy to see with your eye scrolling the charts. Any fool can do that.
In principle it is easy from AFL, EXCEPT where SetBarsRequired() is set to view a short history of historical bars (for speed purposes) and where very short intervals are used... i.e. 15 seconds, 30 seconds, 1 min.... then it would be quite possible that the data simply didn't exist in the arrays to prove it one way or another.
Anyway, problem solved now... I used some different logic. But thanks anyway!
