I would like to run my EA at a predefined interval irrespective of when/ if the EA gets any new ticks from the server. I am trying something like this

extern int     _tick = 1;

//+------------------------------------------------------------------+
//| Start function                                                   |
//+------------------------------------------------------------------+
static int _tick_time;

void start()
   {
      
      if(TimeCurrent()<_tick_time)        { Sleep(_tick_time-TimeCurrent());                         }
      else if(TimeCurrent()>=_tick_time)  { _tick_time=TimeCurrent()+(60*_tick); MyTimerFunction();  }
   }

void MyTimerFunction()
   {
      //My main code...
   }

My question is, can it be possible to have the start (or 'OnTick') function run in parallel with my main code.

With this code can I be sure a new tick will not stop the running of my other code?

y not use

struct MqlTick
  {
   datetime     time;          // Time of the last prices update
   double       bid;           // Current Bid price
   double       ask;           // Current Ask price
   double       last;          // Price of the last deal (Last)
   ulong        volume;        // Volume for the current Last price
  };

You can now use the OnTimer() event handler, with EventSetTimer(), see Mql4 reference by pressing F1 in MetaEditor.

OnTimer() is working well (build 610), what you have tried ?

  1. "Doesn't work" is meaningless - just like saying the car doesn't work. Doesn't start, won't go in gear, no electrical, missing the key, flat tires - meaningless. There are no mind readers here.
  2. Did you turn on the timer? MQL4 Documentation

My EA with only the on timer was placing no trades. When I placed 'Print' statements in the timer function nothing was appearing in terminal log. Only OnTick was printing.

I have the same problem ( Version: 4.00 Build 610 (14 Feb 2014), the test code is below:

define N_minutes 5

int OnInit()
{

EventSetTimer(60*N_minutes ) ;

Print("Error GetLastError() = ", GetLastError() ) ;

return(INIT_SUCCEEDED);
}

void OnTimer()
{

Print(" !!! Timer_in !!!") ;

}

I'm working with MB Trading FX, may be this new functionality is vendor dependent(?)

Thanks
