High Frequency Trading Explained

A rare look inside the secretive world "high-frequency trading," a controversial technique the SEC is scrutinizing in which computers can make thousands of stock trades in less than a second .The high frequency trading algorithms can also -manipulate- the market (predatory algorithms are one example). The argument for liquidity doesn't make complete sense : you only need millisecond liquidity for the high frequency traders! The exchanges already have circuit breakers (suspend trading if stock loses 10% in 15 minutes), why not another rule that limits the advantage and potential for manipulation by HFT: impose a 20 millisecond delay on all transactions! High frequency trading adds no value to the market, its practitioners produce nothing. Therefore, I propose taxing each of these transactions (that number in the thousands) 5 cents. This could take a big dent out of the deficit
