 hello, i am new to mql5 

 Can someone help me?

 How "request.deviation=100" works here?

 then price goes up through buy stop level,  can buy dealed price somehow be more than request.price+ 100*_Point?

can someone explain, if there is mistake somethere

then price goes up more than BUY_STOP price, does deviation works here?

Can you please, use SRC button when posting code.

Please read documentation. Pending orders doesn't need or use "deviation".
