forex robot (ea) launches trade slow

Eleni Anna Branou  
my forex robot launches trade slow. for example ; new bar open price 1550.00 long position start. robot needs to initiate a purchase order. but, until the robot starts, the price is 1550.15. what is the reason of this?

That's your spread or your EA is not coded as it should in order to open a trade right after candle's opening.
