@GraHal:

I’ve updated the code with the MAX formula as you suggested for the divisor side of the division involving only open and close values (not high or low values).

The result: since I strarted running all 21 systems last night non of them have been stopped so far, which is great.

However,  only 1 trade was taken and 7 other trades on 5 pairs on either 10m or 15m were not executed, even though the ProBacktest shows trades in my IG Demo and IG real account.

So not sure why trades are not executed. And how can I find out why?
