Messagebox is closing trades regardless of "Yes" or "No" button clicked - mql4

Question

This has genuinely got to be one of the must ludicrous, most ridiculous situation I have even been in with this coding language.
Is there any reason as to why my trades are closing, regardless as to the button pressed on the prompted Messagebox- despite the fact my EA is only supposed to close trade when the IDYES button is selected?
I click the IDYES button, my trade liquidates, I click the IDNO button, my trade liquidates.
Why is me EA doing things I have not told it to do? The word "fuming" cannot express enough how I'm feeling.

Answer 1

You have defined the return value from your MessageBox as Boolean, however it should be of type int.
int MessageBox(string text, string caption=NULL, int flags=0);
Change your code to
int msgBox = MessageBox("Please confirm the risk on this trade with the margin at the bottom of the terminal. Would you liketo close this trade?"+
"\n"+
"\n£"+DoubleToStr(((tickvalue * LotSize)*stopLossPoints)+ tradeSpread,2),"Information", MB_YESNO|MB_ICONQUESTION|MB_TOPMOST);
