Hi, my system involves placing limit sell orders at pre determined prices, now does anyone know who gets priority, like who is 1st in line to be executed @ say 1012.25. because I always get my order in say 30mins before the strike price, I see multiple orders going off with just me flashing waiting to be filled. It seems like the ES has to always go 1tick above my exit price before I get a fill!! How come!? who are all these people getting filled before me!??
