Expert advisor log

 

The reference says for the Print function that "It enters a message in the Expert Advisor log. Parameters can be of any type."

But, my "/MQL4/Logs" folder is empty.


Where is the "expert advisor log"?

 

I have a second question: I get "return value of 'OrderClose' should be checked" warning for OrderClose function.


What does "checked" mean here?

Can you please show me a sample code for eliminating this warning?

Thanks.
