Can you please advise how to open a position on a currency pair which does not have an EA attached? For example: Is my Expert Advisor attached to EUR/USD chart and I need to add into my code the opening of a position on GBP/CAD? When I do the following:

OrderSend("GBPCAD",OP_BUY,Lots,Bid,3,loss*Point,TakeProfit*PPoint," ",123,0,Red);

There is an error in the log:

EURUSD,M15: unknown symbol name GBPCAD for OrderSend function

EURUSD,M15: OrderSend error 4106

Sincerely.

If I'm not mistaken, this must be deleted:

//Linear regression trendline
ObjectDelete(period+"m "+LR.length+" TL);
ObjectCreate(period+"m "+LR.length+" TL",OBJ_TREND,0,Time[start.bar],LR.price.1,Time[end.bar],LR.price.2);
ObjectSet(period+"m "+LR.length+" TL",OBJPROP_COLOR,Orange);
ObjectSet(period+"m "+LR.length+" TL",OBJPROP_WIDTH,2);
ObjectSet(period+"m "+LR.length+" TL",OBJPROP_RAY,false);
//... standard deviation...

I could be wrong as I'm not a proger =)

Depending on the brokerage house pairs may have different names, so you may want to know what you are dealing with.
Print(Symbol());
and show us what it says in the log.
 
Techno:
Depending on the dc, the names of the pairs may be different, so that you know what you are dealing with, write and show the inscription that appears in the log

you are not trying to do this in the Strategy Tester?

Something's wrong, the line is gone, but so is everything else :(
