SL not working in strangle

Strategy
#1

I have created a short strangle strategy. I have added 20 point SL but its not working. Suppose I am selling at 100 premium SL is 120. But SL never hits and position get exited at random values. some times 140, 150 like this. I am testing strategy as paper trade but I am on 300Rs paid plan. Screenshots attached.

You have to set frequency of check as continuos check. If strategy set frequency of check say 1 min Or 5 min by that time price might have moved higher
