Hi, Let's say, I'm running an indicator on a chart and I want to program it once the indicator is unloaded / closed manually or automatically, it will automatically initiate a preferred template at \templates\***.tpl. I tried to use only the ChartApplyTemplate(0,default.tpl) in the OnDeinit(const int reason) block, if I do not modify, change any input variables and compile the indicator, it can work well accordingly. However if I modify, change any input variables and compile the indicator, the MT4 will get hang and shut down. Can anyone advise...

void OnDeinit(const int reason)
  {
   if(reason==1)
     {
      ChartApplyTemplate(0,templateName);
      int errorCode=GetLastError();
      if(errorCode!=0)
        {
         Alert("Error Code: "+(string)errorCode);
        }
     }
  }
