Counting number of times an indicator has triggered

[BaoBao1102]

Dear,

Recently i'm developing an indicator, and i need to get the barindex of the first time that indicator has triggered (it would trigger multiple of times, but i only need to get data of first time).

As shown in the picture, the indicator has triggered twice but i only need the barindex of first one and count how many times is has triggered.

Are there any buildin fuction to that (like barssince for counting bars) or any trick ?

Thx a lot for helping me.

Best way to find first occurence in an array

I assume you already know how to find the peaks. If so, the logic for identifying the first one is straightforward: isPeak = // Your logic here countPeaks = Cum(isPeak); firstPeakBar = ValueWhen(countPeaks == 1, BarIndex()); If you did not in fact want to look at the ENTIRE array (which would typically be the case), you could use SumSince() instead of Cum() to start the counting from some other event, for example the first bar that's in range.

So something like this,

Condition = // your indicator;
CountConditions = Cum(Condition); 
FirstConditionBar = ValueWhen(CountConditions == 1 AND Condition, BarIndex());

I've done it by trick using barssince but your quoted solution is way better!
Thank you very much Portfoliobuilder
