You cannot be serious?
TH said:For more than twenty years, Simons' Renaissance Technologies hedge fund, which trades in markets around the world, has employed complex mathematical models to analyze and execute trades, many of them automated. Renaissance uses computer-based models to predict price changes in easily-traded financial instruments. These models are based on analyzing as much data as can be gathered, then looking for non-random movements to make predictions.[7] Some also attribute Renaissance performance to employing Financial signal processing techniques such as pattern recognition.
Found a WSJ piece from last year on them.

Renaissance Technologies LLC, a hedge-fund heavyweight, has been bruised in the market's recent turbulence.
Two of the three hedge funds that the company makes available to outside investors have suffered sizable losses this month, largely due to the big drop in the Japanese yen, investors say.
At the same time, Renaissance continues to raise cash at a slower pace than some had expected. The firm manages about $6 billion of cash for outside investors—down from about $25 billion in 2007.
According to the above article, if Renaissance have an algorithm or 3 they clearly need some tweeking.
As i said, the fact that no infallible or even consistently profitable algorithm exists means that the data is useless for predicting price movement = patterns are useless.
