  Hello,

  how can I refer to a past condition NOT by period with square brackets […] BUT by last time, 2nd last, 3rd last time and so on?

  Meaning and I dont care when exactly the condition was true, I just want to get values from it.

  Please help forum brains

  Thx & cheers

  You need to use a FOR…NEXT iteration.

  You simply set the number of the occurrence you want to retrieve and it will be returned in variable EventBar (0=no occurrences):

  N = 3 //3rd occurrence Avg = close CROSSES OVER average[20,0](close) //event to be searched for EventBar = 0 Count = 0 FOR i = 0 TO BarIndex - 1 IF Avg[i] THEN EventBar = BarIndex[i] Count = Count + 1 IF Count = N THEN Break ENDIF ENDIF NEXT

  1 2 3 4 5 6 7 8 9 10 11 12 13

  N        = 3       //3rd occurrence Avg      = close CROSSES OVER average[20,0](close) //event to be searched for EventBar = 0 Count    = 0 FOR i = 0 TO BarIndex - 1    IF Avg[i] THEN       EventBar = BarIndex[i]       Count    = Count + 1       IF Count = N THEN          Break       ENDIF    ENDIF NEXT

  Alternatively use an array to store the value and increase the array location by +1 each time you store a value.

  Not tested.

  if (your event) then a = a + 1 $myvalue[a] = close //store closing price at time of your event endif //retrieve 2nd to last event if a >=2 then secondlast = $myvalue[a-1] endif //retrieve 5th to last event if a >=5 then secondlast = $myvalue[a-4] endif

  1 2 3 4 5 6 7 8 9 10 11 12 13 14

  if (your event) then a = a + 1 $myvalue[a] = close //store closing price at time of your event endif   //retrieve 2nd to last event if a >=2 then secondlast = $myvalue[a-1] endif   //retrieve 5th to last event if a >=5 then secondlast = $myvalue[a-4] endif

  Vonasi‘s solution is much better because you don’t waste time to scan bars backwards, which can be very time consuming if you want retrieve, say, the 100th event!
