HFT, from Duncan Coker
Despite what I have read I am not convinced the HFT in aggregate are profitable. Buying High, Selling low, and making it up on volume just does not seem like a good business model to me. The research on HFT seems unadjusted for survival bias. They study the biggest and most profitable firms to see how big and profitable they are. I personally know an HFT firm that made money 3 years in a row, then after 4 months of bad performance they realized their edge was gone and they closed shop. I am sure they were never included in HFT research. I use limit order so I suppose HFT is taking the other side and the jury is still out.

Of course, Dunc, it should be like all things sports MX. Top 10 sleep in the Hilton and ride in the Factory rig and the next 10 best in the world sleep in their trailer in the pits 20-99 are part timers and lose money racing.
