Read the freaking article! I posted it direct from the WSJ!
Computers make the trades.....no one person analyzes pages of data.
You are either blind or willfully obtuse to the facts.
No shit computers make the trades no one is arguing that... But you speak of unfair advanteges... Or excuse me the article speaks for you since you are incapable of articulating your own opinion and are pawning an article that is clearly agenda driven as the end all be all in the matter.
I am a succesffull retail trader and the liquidity that the HFT create add to my margins... And the circle of traders that i know say the same thing... I prefer to buy/sell at 1 penny margins with hft than the 50 to 100 penny margins withouGrr.. and if you speak to anyone who trades succesfully they will say the same thing..
