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?

File Operations via WinAPI

Environment MQL4 is based on the conception of safe "sandbox": reading and saving files using the language are allowed in some predefined folders only. This protects the user of MetaTrader 4 from the potential danger of damaging important data on the HDD. However, it is sometimes necessary to leave that safe area. This article is devoted to the problem of how to do it easily and correctly.

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
