It seems that MQL4 EventSetTimer is not supported for replay?!

[Amy Liu]

I wrote a program to use timer event. I doubt that EventSetTimer is not supported for replay. Since I didn't find any discriptions in the document, I publish this topic to get confirmation.

Here are the code:

//| Expert initialization function                                   |

int OnInit()
  {
//--- create timer
   if(!EventSetTimer(seconds))
     {
      int error=GetLastError();
      PrintFormat("EventSetTimer FAILED: #%d[%s]", error, ErrorDescription(error));
     }
      
//---
   return(INIT_SUCCEEDED);
  }
//+------------------------------------------------------------------+
//| Expert deinitialization function                                 |
//+------------------------------------------------------------------+
void OnDeinit(const int reason)
  {
//--- destroy timer
   EventKillTimer();
      
  }
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
//---
   
  }
//+------------------------------------------------------------------+
//| Timer function                                                   |
//+------------------------------------------------------------------+
void OnTimer()
  {
//---
   Print("OnTimer");
  }
//+------------------------------------------------------------------+

No compliing error(s) or warning(s).

Then I replay it in Strategy Tester. Settings below:

 

It gives the following error: “2014.09.06 10:26:26.023 2014.09.01 00:00 TimerTest EURUSD,M1: EventSetTimer FAILED: #4051[invalid function parameter value]”

But when I load it to a live demo chart, the above error disappears:

The back tester does not work with OnTimer() events.

If you want to process data in the back tester, I would advise using the OnTick() function instead.

Confirmed, thank you!
