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

Thank You very much for your help.

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 Ronaldo,

Thanks for the advise, I'm more confused mow then before. But that was mot my question though, please reread.....

Thanks

 
Mick, your "if" statements are simply written wrong. should be if (logical exp) then... also for equalities in logical exp, be sure to use ==
 

Trend=int fnIndTrendDirection(candles); /// can not use int after =
fnTrade(LotSize,StopLoss,TakeProfit,Trend);

Where are the functions fnIndTrendDirection(...) and fnTrade(...) ???
