I'm curious how much is the biggest profit you've made in the shortest amount of time. This should be per contract not some gaudy number based on taking on a 100 contract position. I imagine scalpers have the edge here. Last Friday I went short the ES into the NFP data. In 08:30:00. Out 08:30:03 3 secs, 10 Points. Lucky I use BT, never would have gotten in that fast without it. I'm a swing trader usually so this was an amusing trade to me. But I imagine others have better ones, perhaps to do with Fed announcements.
26.75 ES points in 43 seconds. http://www.elitetrader.com/vb/showthread.php?s=&threadid=101842 Pabst grabbed a few more points.
