How do you expect us USERS to help you when "OnChartEvent() does not work"? We can't fix OnChartEvent, only MQ can.

OnChartEvent() is not yet implemented in the Strategy Tester. What are you trying to do with it ?

I have try to use buttons for trading during a backtest, but without the OnChartEvent() i cannot let the EA open a trade when i click a button, or is there another way to do that?

same problem here, implementing OnChartEvent in Tester is really important. Without backtesting its very hard to develop

I know this is a an old thread, but I recently needed to debug some of my code that implements "buttons" to control certain aspects of an EA I was coding and had need for it to work in the Strategy Tester.

The solution I came up with was to check the button states on every incoming tick when the EA was in Visual Mode.

In other words, something like this:

void CheckResetButton()
{
   if( bool( ObjectGetInteger( 0, idResetButtonObject, OBJPROP_STATE ) ) )
   {
      Print( "Reset Button Clicked" );
      ObjectSetInteger( 0, idResetButtonObject, OBJPROP_STATE, false );
   }
}

void OnTick()
{
   // Only needed in Visual Testing Mode
   if( IsVisualMode() )
   {
      // Check Chart Buttons in Visual Mode
      CheckResetButton();
   }

   return;
}

@FMIC, nice simple solution.

@PlanandTrade, depending on your use case the following solution may or may NOT be possible (for one use case of mine it worked):

  • implement the reaction to the events in mqh file
  • for the Strategy Tester you implement an additional indicator that listens to the events and calls the reactions in the mqh file
  • for Real Time, you adjust your EA source code to use the mqh file event reactions or use the EA with the indicator
