I admire the guy's work ethic but he has an extremely small edge of less than a tick (after the lowest commissions possible). But then again, even in equities its hard to see someone with an edge of greater than .01/share. One guy has a razor slim edge of .005-.007/share - but he does 200K+ volume a day and never has a down day it seems - maybe once in a very long while due to a big error. I wonder how these guys would have fared back in the days of .01/share commissions. I recently met a guy that did +.09/share for march but he does a lot of averaging down and overnights.
The article is decent. but good would be to see a youtube video of that guy trading highlights, with a audio commentary then I would even pay good money to see
