Spyder man I am not sure what you are talking about! If 99 out of 100 people consistanty pull the trigger, and get filled instantaneously. however the other 1 % has to wait 3 to 4 minutes, for a fill , on a regular basis, then some thing is not right! I am due a fill too! unless something is midadjusted etc. I have been trading emini dow for the last couple of months with that problem. I just switched to mini s&p with the same problem, so it is not the exchange. I use a limit order +4. Smart routing. that't plenty of time to get filled. I have heard that smart routing can be slow, but not that slow. How many people here use smart routing? and what do you suggest. And why is do I get filled 100% of the time on the entry, but not on the exit, this is the part that is crazy! the color of the light is green until I cancel.
