Since you define Trend to be a bool and you want to assign a boolean value to this variable, the function fnIndTrendDirection(candles) should be delcared as bool.
So you have and no int declartion here allowed
Trend= fnIndTrendDirection(candles);
and make sure your fucntion is declared as follows
bool fnIndTrendDirection(int candles)
{
your codes
return(answer);
}
where answer is either true or false

Hi,
This is my first try at coding an EA, i'm not a programmer, and I have a lot of problems with compile errors.
I'm fiddling around trying to figure out how "functions" work, so I'm trying to write a very basic one and figure out by my mistakes but it keeps telling me that "EXPRESSION ON GLOBAL SCOPE NOT ALLOWED" could someone tell me what is going on?
Here is my code, i'd like to know WHY this is happening, what I'm doing wrong.
Thanks
Roger
