You should not be getting info about the account in OnInit as it may not be loaded yet.

OnInit is only called once when the EA initiates so it will not be updated. So set your comment in OnTick

void OnTick()
{

Comment( StringFormat( "Equity = %.2f; Balance = %.2f; Free Margin = %.2f", AccountInfoDouble( ACCOUNT_EQUITY ), AccountInfoDouble( ACCOUNT_BALANCE ), AccountInfoDouble (ACCOUNT_MARGIN_FREE) ) );

} // Right? It doesn't work.
 
IgorFX Trading #: Right? It doesn't work.

It does work, provided it is an Expert Advisor (EA) and not an Indicator (you did not specify which one you are coding).

If it is an Indicator then you have to use OnCalculate() instead of OnTick().

Also, if you don't have any trade activity going on, then obviously those values will not change.

Got it. Yeah, it was an indicator.

 

Given that you are having so much difficulty with MQL4, I suggest reading and following the lessons in the following book. It is how I started with MQL4.

EDIT: But make sure to get the latest edition with MQL4+ code.

Fernando, under each of my posts under which you answer, you mention my level of programming knowledge and that I should do this or that. I know what I need to do. Just answer my question, please, and thank you very much!

I've read this book recently. 


And that I realized that it is not about reading words, but about practice. It's a slow road, I'm done with this book. I chose the path of learning for myself by collecting and filtering information.  You may not understand, but the main thing is that I understand. Accordingly, one of the ways to learn programming is to ask questions, is it bad? The book will not answer all my questions, what idea of ​​an adviser will come into my head, I will implement it by collecting information on the MQL5 website and others. It's a billion times faster. I am grateful to this book all the same, I borrowed some functions from there anyway.
