MT4 Strategy Tester doesn't generate ticks near to the end of M5 bars

[Miroslav Popov]

MT4 Strategy Tester generates ticks on a M5 chart every 2-3 seconds, but not at the end of the bar.

Expert:

   void OnTick()
     {
      if(Volume[0] == 1) Print("======================================");
      string time = TimeToString(TimeCurrent(), TIME_DATE|TIME_MINUTES|TIME_SECONDS);
      string bid = DoubleToString(Bid,_Digits);
      string ask = DoubleToString(Ask,_Digits);
      Print("TimeCurrent: ", time, ", Bid: ", bid, ", Ask: ", ask);
     }

Result:

This happens for every M5 bar. There is no ticks for the last 25-35 seconds.

This is definitely a bug. Any comments?

i am not sure but when the print command is triggered too many times too fast it will inject a 30 sec timeout where nothing will be print maybe you try to slow down simulation speed.

or put in a

Sleep(X);

after each print line.

Edit after seeing the time print i looks like it is indeed a bug.

[Miroslav Popov]

It is slowed and I'm tracking the print lines visually. I noticed this bug when users of my product reported an issue with the backtester.

This issue appeared recently. It works fine in MT5.

[Marco vd Heijden]

did you download the full history in history center?

[Miroslav Popov]

I never do it. It replaces the data from my broker.

[Marco vd Heijden]

well are all of your clients using the same broker of is there a difference and if so does it show on all terminals broker independent then it could very well be an MT4 issue.

[Miroslav Popov]

I modified the expert to print only the last tick info from the previous bar.

string previousRecord = "";

void OnTick()
  {
   string time = TimeToString(TimeCurrent(), TIME_DATE|TIME_MINUTES|TIME_SECONDS);
   string bid = DoubleToString(Bid,_Digits);
   string ask = DoubleToString(Ask,_Digits);
   if(Volume[0] == 1)
      Print(previousRecord);
   previousRecord = "TimeCurrent: " + time + ", Bid: " + bid + ", Ask: " + ask;
  }

The interesting is that the last tick for an M5 chart is either at xx:24 or xx:35 with one exception for 20:04:23

Same behaviour on EURUSD M15 chart:

yes well timecurrent() returns the last known servertime therefore it should be considered a brokker server issue, at least that's what i can make of it.

you can check in history center if these missing bars actually exist or not.

I think you missed the point. There is no missing bars, but the problem is how ticks are emulated with the Strategy Tester. Seems no tick are generated in the last 25 seconds of a bar.

[Marco vd Heijden]

Yicks i ment missing ticks.
