Error A positive integer field is expected

  I got the Calculation error: ‘Error in the indicator… A positive integer field is expected with Count’

  Count# of consecutive lower close and present in negative integer

  Decrease = Close < Close[1] Count = 0 FOR i = 1 TO BarIndex DO IF Decrease[Count] THEN Count = Count - 1 ELSE BREAK ENDIF NEXT RETURN Count

  1 2 3 4 5 6 7 8 9 10

  Decrease = Close < Close[1] Count = 0 FOR i = 1 TO BarIndex DO IF Decrease[Count] THEN   Count = Count - 1 ELSE   BREAK ENDIF NEXT RETURN Count

  I have to re-code it as

  Decrease = Close < Close[1] Count = 0 FOR i = 1 TO BarIndex DO IF Decrease[Count] THEN Count = Count + 1 ELSE BREAK ENDIF NEXT n = 0 - Count RETURN n

  1 2 3 4 5 6 7 8 9 10 11

  Decrease = Close < Close[1] Count = 0 FOR i = 1 TO BarIndex DO IF Decrease[Count] THEN   Count = Count + 1 ELSE   BREAK ENDIF NEXT n = 0 - Count RETURN n

  Why ?

  If you discovered how to work it out correctly it’s because you got the hang of it!

  You answered your own question. If a negative integer is not allowed then don’t use one and use a positive one that is allowed instead!

  Because COUNT variable is sometimes negative! 😉 Not possible to use a variable with a negative offset!

  Decrease[-1] will flash that error.

  Haha. Now I realized my mistake. I copy this example somewhere without realizing that it use the Count to index. I ‘assume’ it use the variable i to index.

  The correct code should be

  Decrease = Close < Close[1] Count = 0 FOR i = 0 TO BarIndex - 1 DO IF Decrease[i] THEN Count = Count - 1 ELSE BREAK ENDIF NEXT RETURN Count

  1 2 3 4 5 6 7 8 9 10 11

  Decrease = Close < Close[1] Count = 0 FOR i = 0 TO BarIndex - 1 DO IF Decrease[i] THEN   Count = Count - 1 ELSE   BREAK ENDIF NEXT   RETURN Count

  I learn the danger pf copy/paste code.

  Thks everyone for taking interest and interesting comments.  Cheers.
