res=OrderSend(Symbol(),OP_SELL,LotsOptimized(),Bid,3,Bid+(Stop_Loss*Point),0,"",0,0,MAGICMA);
Next time:
I realized, the reason, EA opens positions again and again, but I don't understand why, because there is a "return" condition in the EA!?
Every tick the conditions hold true the EA will attempt to send an order.

I understand, but how can i set, that EA opens position when there is no opened position, or when EA get a new buy or sell signal?
Thanks
Why isn't enough this?
if(CalculateCurrentOrders(Symbol())==0) CheckForOpen();
else CheckForClose();
I think if there's no opened position, checks for open, and if there is, checks for close...

Your CalculateCurrentOrders() function will return zero when there are no orders (that belong to symbol and magic number) so CheckForOpen() will only be called if there are no orders... I am not sure I understand what's the problem? Maybe u can explain again...
My problem is, after that I put SL and TP, my expert opens postition on every new tick, but I don't understand why!?
I would like to solve, that EA open position when there is no opened position.
Thanks!

Hey,
What does it mean... "String parameter expected"? I get this error message, when i test my EA with this StopLoss...
