Infinite loop within the program!

  Hi, I have written the program below for ProScreener:

  Condition1 = Volume > 1000000 Period = 30 Condition2 = Close/Close[Period] > 1 HighestNegativePercentageDifference = 0 FOR i = Period DOWNTO 1 DO FOR j = i DOWNTO 1 DO IF Close[i] > Close[j-1] THEN Percentage = (1-(Close[j-1]/Close[i]))*100 IF Percentage > HighestNegativePercentageDifference THEN HighestNegativePercentageDifference = Percentage ENDIF ENDIF NEXT NEXT PercentIncreaseOverPeriod = Close/Close[Period] Ratio = PercentIncreaseOverPeriod/HighestNegativePercentageDifference SCREENER[Condition1 AND Condition2](Ratio AS "Ratio")

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

  Condition1 = Volume > 1000000   Period = 30 Condition2 = Close/Close[Period] > 1   HighestNegativePercentageDifference = 0 FOR i = Period DOWNTO 1 DO FOR j = i DOWNTO 1 DO IF Close[i] > Close[j-1] THEN Percentage = (1-(Close[j-1]/Close[i]))*100 IF Percentage > HighestNegativePercentageDifference THEN HighestNegativePercentageDifference = Percentage ENDIF ENDIF NEXT NEXT   PercentIncreaseOverPeriod = Close/Close[Period]   Ratio = PercentIncreaseOverPeriod/HighestNegativePercentageDifference   SCREENER[Condition1 AND Condition2](Ratio AS "Ratio")

  I attached a screenshot of the error that appears. Could someone please assist me and let me know what am I doing wrong?
  Thank you.

  Nested FOR/NEXT loops are a nightmare for the proscreener engine to correctly compute. That’s why you get this error window, even if your code is looking ok.

  You’ll have to find a solution with a SUMMATION of boolean conditions results for your second nested FOR/NEXT loop between line 8 to 15.
