There is a modern day Gold Rush thats been happening as computers have become more sophisticated in the trading arena. All the price data that is generated from a few exchanges globally, and the individual issues traded. Man cant compete with machine logic implementation and pattern recognition of machines that occurs in milliseconds. If you look at all the price data, there is literally 'gold in them hills'. Lots of inefficiencies that can be exploited. The 'edge' can be temporal or it can be everlasting.
