Why couldn't you do it now?



Well I could try. But it's not going to be any easier now than it was in 2010. For four months I tried everything I could think of to keep it profitable but in the end nothing worked so I had to shut it off.


I have two theories why it stopped working. I think the market sped up. Latencies are always getting lower and your strategy that worked at 10 ms didn't work with players that are at 1 ms. Also, you might have been gamed because your strategy was easily predictable or you were putting too many trades through the same broker/exchange/etc.
