debugging: break code runing on Variable1==true

[Joze Silc]

Hello

Is it possible to set a conditional stop in MQL5? For example if Variable1==true

How?

Yes, that is possible.

Basically, you call the function DebugBreak(), and you can do so with an if-statement.

There are debug helper libraries available in code base, they support some sophisticated debug stuff that comes in handy when developing code.

I have for example over 100x in code this statement:

PREDICTION=+1

Why must I set breakpoint over 100 times instead "somewhere" set only one condition: if PREDICTION==+1 then stop running my code .....

?!

You did not explain yourself properly in your posts. Please explain in detail.

What is it that you want to "stop"?

• Do you want to halt execution in the debugger?
  
• Do you want to return from the event handler?
• Do you want to stop and remove the program from the chart?

Explain in detail what it is you want to achieve. Show example code if necessary?

As explained in post #1 by @Dominik Egert

if( Variable1 ) DebugBreak();

Here is the example code from the documentation: Documentation on MQL5: Common Functions / DebugBreak

//+------------------------------------------------------------------+
//| Script program start function                                    |
//+------------------------------------------------------------------+
void OnStart()
  {
//--- compile the file using F5
//--- in debugging mode, if i == j, stop at the DebugBreak() string  
   for(int i=0,j=20; i<20; i++,j--)
     {
      if(i==j)
         DebugBreak();
     }
  }
