Custom Indicator Not Refreshing

New comment
 

Hi All,

I have a custom indicator that paints arrows on my chart when specific criteria is aligned. The problem is that it only re-paints when I refresh it, it should just do this automatically. The source code is below, can anyone tell me what code I can add to fix this?

  1. int limit=Bars-2;
   if(ExtCountedBars>100) limit=Bars-ExtCountedBars-100;
    Bogus. After the first time counted = Bars so limit is negative and nothing is drawn. Try int limit = Bars -1 -ExtCountedBars;

  2. You should stop using the old IndicatorCounted and start using the new Event Handling Functions - Functions - Language Basics - MQL4 Reference
  3. See also How to do your lookbacks correctly.
