Now, I have read each and every post and I think there are several notions of HFT and contrary opinions.
Let me address all with a question:
There are two traders Joe and Bob. Joe is in New York and has broadband connection and Bob is in Argentina and has a DSL connection. They both trade NYSE stoks.
Joe sees an offer at $10.00 for 100 shares of XYZ stock on his screen at T1 = 1:00 PM EST. Apparently, Bob will see that after a few ms at T2 = T +dt due to connection delays.
Now, Bob intended to hit the offer would it come through but Joe hit it before and the offer went up to 10.01. When Bob hits the offer for a market order to buy 100 XYZ he gets the price of 10:01.
Q1: is Joe front running Bob?
Q2: Since Bod knows he is at a serious disadvantage why is he insisting to trade with market orders and not limit orders? Had Bob placed his order 5 minutes before he would have gotten his price.
My answers:
Q1: No
Q2: Bob is an unimformed or stupid trader
My conclusion:
HFT makes money because there are so many stupid traders around that continue to day trade the old fashioned way when technology has advaned so far. HFT does not affect short-term position traders or investors who place limit orders long before the price is reached and anyone who claims it does he does not understand how markets work, probably has never traded and is just spewing crap all over the place.
