You don’t get it. There computers are set up to “PEEK” before the other peoples trades are ever actually executed. And then after they peek then they can still place a trade before you that is based on what your trade is going to be.
It is no Different than in poker when you have a way to see the other guys cards before you place your bet.
Thanks for your help, FReinds - you are correct. I didn’t have a full understanding.
If latency between systems allows someone to see someone else’s trade request and act on it before it is fulfilled, then that ain’t right.
My question remains, but I neglected to go past zero seconds into negative time periods. ;)
