There is much more to the stock-market than meets the eye: highly complex and sometimes secretive trading methods, known as "dark pools", manipulate the market in power's favor.

It started last July, when a former Goldman Sachs computer programmer was arrested for allegedly stealing proprietary high-frequency computer code.

A few weeks later, The New York Times ran a cover story that credited the trading technique with being able 'to master the stock market, peek at investors’ orders, and, critics say, even subtly manipulate share prices,' to the tune of '$21 billion in profits,' during the financial cratering of 2008."
