Sergey Gritsay:
put everything I highlighted into the OnTick() function

Can you explain the difference?

[Renat Akhtyamov]

Michail_David:
Can you explain the difference?

You switch the programme on and it only calculates when you switch it on, and then it does not calculate or recalculate anything, even in the tester

Well, that's a bad start...

You were correctly told above - how to do

Renat Akhtyamov:

Such a bad start... You have been told above how to do it correctly

You may not open trades because of it. You're right?

[Renat Akhtyamov]

Michail_David:
And because of that, trades may not open either. Right?

100%

[Michail_David]

Renat Akhtyamov:
100%

The tester still won't open the trades. I will try it on a demo account. Thanks for the tip

It will be the same on the demo, just longer.

If you want to share, publish the code

You may not have understood exactly what you were told to do.

For example - move the first couple of lines

double Margin_Percent; //Используемые средства для открытия ордеров
double Lots;//Определение общего количества лотов
....................
//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
     Margin_Percent=AccountFreeMargin()*Percent/100;
     Lots=Margin_Percent/MarketInfo(Symbol(),MODE_MARGINREQUIRED);
     .........
  
//------
  }

Yes. I moved the whole thing with the data types. Thank you for telling me how to do it.

Michail_David:
Yes. I've moved it all together with the data types. Thank you for telling me how to do it.

I hope that OnInit() has some value assigned to the Percent variable?
