This is what?
What is this?

before the start is announced:

bool Buy = FALSE;

before the start is announced:

I can't understand, are you using your function to open pose or Kim's?
If it's Igor's, I roughly wrote an arbitrary call (not specific to your strategy), but if it's my own, there's not much information...
 

Hello, Could you please tell me how the construction is implemented in MQL4:

"If the closing price of the EURUSD minute bar at 17.17 is higher than the opening price of the EURUSD minute bar at 17.11, then".

The current time does not have to be 17.18, it can be later within a given day.

Maybe there is more than one way to do this??? (I'm just starting to learn the language)

 
Hi all, I can't figure it out:

When testing this prose code, a message never popped up in the log. What is the reason? The price for the month crosses EMA(13) many times hence the message should have appeared but it didn't(. Who can help!

Look at this variant
 

Hello, could you please tell me in which cases a GetLastError() 4051 error occurs when setting a pending order. What can "Invalid value of function parameter" mean? Everything seems to be the same as always, but there is an error. Thank you!

Sorry. I found it myself.

 
Vinin:

Look at this option
Thank you, for your help. Much obliged=)
 

The logical operation || (FXI1<0 && FXI2>0 || RSI<50 && RSI>30) does not work. What is wrong? Thank you.

There is an established procedure for logging operations depending on the type.

If I understand correctly what you are interested in, try it. 

if ((FXI1<0 && FXI2> 0) || (RSI<50 && RSI> 30))
   {
   }

The sequence of logging operations is described in the documentation and tutorial.
