Useless error message

  Can anyone explain what this message actually means.  I’m calling an indicator for its current value from a screener (0, 1 or -1).  Then I want to list which securities have an indicator value of 1 or -1.

  I appreciate it is not always possible to return a line number but a better description with examples of what would produce this error would be helpful.

  ProScreener don’t allow lookback in the past for more of 254 bars.

  I already made some kind of walk around of this limitation in the Spanish forum, let me look for it.

  If you are looking about Highest or Lowest values in the past than more 254 bars, this code will certainly help you :

  once previousbar = 0 once hh = 0 once ll = low if(barindex>previousbar) then previousbar=barindex hh=MAX(hh[1],high) ll=MIN(ll[1],low) endif RETURN hh,ll

  1 2 3 4 5 6 7 8 9 10 11

  once previousbar = 0 once hh = 0 once ll = low   if(barindex>previousbar) then previousbar=barindex hh=MAX(hh[1],high) ll=MIN(ll[1],low) endif   RETURN hh,ll

   

  This is an indicator to store the Highest and Lowest values from the beginning of your chart. In a screener you should call “hh” and “ll” to make conditionnal test for what you are looking for.
