Have you ever played Poker? Sometimes you win; sometimes you lose. The whole time you are wondering what cards the other players are holding. 'Does he have a King. If not, I will WIN!' (Too bad, he had the King!) As I have outlined in previous posts, the markets, or, trading them at least, is like gambling, because you never know the 'hand' that the market is getting ready to play. You take your position and see if you can win the game. Yet there is another game being played in Wall Street and the City these days... Some people are playing Poker whilst looking right at everyone else's cards!
It's called High-Frequency Trading (HFT). HFT is done with light-speed computers trading anything from shares to commodities literally thousands of times a day, making many small but consistent profits per trade, often just one penny per share! This is done by buying and selling these instruments over a period of mere seconds - or even fraction of a second!

How are these trades so consistent? How could a computer possibly know the direction a stock will move in one second?! The answer is, by this point obvious: The computers cheat. They see the Order Book and know the coming Bids and Asks*. Simple computer programmes are written to buy and sell these stocks based on future bids and asks being met by exchanges.This is known as Front Running, essentially having insider information and profiting from it.
Another strategy used by HFT is known as Quote Stuffing. This is when the HFT computers place a large number of orders to influence the price of a financial asset and then immediately cancel them. This allows them to minipulate the market and profit from the future price change.
How do these strategies perform?

Quite well actually! The returns seen in the chart to the left look larger-than-life, too good to be true. Normally, they would be too good to be true, but when you can read the Order Book...
Basically, HFT is a license to mint money. It is currently legal but is under increasing scrutiny from the press and the public. While many people in the industry see HFT as corrupt and manipulative, most hold their nose.
Why? Liquidity. Because HFT relies on thousands of trades per day, these traders make life easier for other traders. When trading common shares, you can rest assured that your bids will be hit almost instantaneously thanks to HFT.
What's my take? Let 'em stay. But I want to see more regulations. Don't let HFT place false bids or manipulate the market. Only quantitative strategies should be acceptable.
*A Bid is the price a buyer is willing to buy at. An Ask is the price a seller is willing to sell at.
