DRAW into the future with DateToBarIndex error

  I was testing a piece of code to draw segments in the future with this code (Dax, Daily TF) using DateToBarIndex:

  GG = 6 MyDay = OpenDay MyMonth = OpenMonth MyYear = OpenYear DayMax = 31 TestX = 1 MyGG = GG WHILE Test = 1 IF MyMonth = 4 OR MyMonth = 6 OR MyMonth = 9 OR Month = 11 THEN DayMax = 30 ELSIF MyMonth = 2 THEN DayMax = 28 IF Year MOD 4 = 0 THEN IF Year MOD 100 = 0 THEN IF Year MOD 400 = 0 THEN DayMax = 29 ENDIF ELSE DayMax = 29 ENDIF ENDIF ENDIF MyDay = MyDay + MyGG IF MyDay <= DayMax THEN Test = 0 ELSE MyDay = MyDay - DayMax MyMonth = MyMonth + 1 IF MyMonth = 13 THEN MyMonth = 1 MyYear = MyYear + 1 ENDIF DayMax = 31 MyGG = 0 ENDIF WEND MyDate = (MyYear * 10000) + (MyMonth * 100) + MyDay DRAWSEGMENT(barindex,high,DateToBarIndex(MyDate),high) RETURN

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39

  GG      = 6 MyDay   = OpenDay MyMonth = OpenMonth MyYear  = OpenYear DayMax  = 31 TestX    = 1 MyGG    = GG WHILE Test = 1    IF MyMonth = 4 OR MyMonth = 6 OR MyMonth = 9 OR Month = 11 THEN       DayMax = 30    ELSIF MyMonth = 2 THEN       DayMax = 28       IF Year MOD 4 = 0 THEN          IF Year MOD 100 = 0 THEN             IF Year MOD 400 = 0 THEN                DayMax = 29             ENDIF          ELSE             DayMax = 29          ENDIF       ENDIF    ENDIF    MyDay = MyDay + MyGG    IF MyDay <= DayMax THEN       Test = 0    ELSE       MyDay   = MyDay - DayMax       MyMonth = MyMonth + 1       IF MyMonth = 13 THEN          MyMonth = 1          MyYear  = MyYear + 1       ENDIF       DayMax = 31       MyGG   = 0    ENDIF WEND MyDate = (MyYear * 10000) + (MyMonth * 100) + MyDay DRAWSEGMENT(barindex,high,DateToBarIndex(MyDate),high) RETURN

  at line it only accepts, as an offset into the future, from 2 to 31 days, otherwise an error is reported as from attached pics (Draw1 is correct, with 31, while Draw2 returned an error as soon as I incremented the variable to 32).

  Is this a limit or a bug?

  Making it a strategy and GRAPHing all variables, the future dates calculated are GRAPHed correctly, so there should be no error in the calculation code.
