Hi, it’s a pleasure to post my first message here A setup found with average mobile give a value to signal S1 I want to give a value to S2, if S1 was at least one time equal to 1 during the last 50 periods and condition3 Here as I tried but i failed 🙁 If Setup1a then S1 = 1 Elsif Setup1b then S1 = -1 Else S1 = 0 Endif if summation[50](S1=1)>0 and condition3 then S2 = 1 elsif summation[50](S1=-1)> 0 and condition3 then S2 = -1 else S2 = 0 endif
