I'm a trading system developer who has a "Swing Trade" system that actively and profitably trades Crude Oil (either the big contract or the mini). It trades about once a day or once every two days. It is designed to hold over-night, but could also be daytraded. It requires that you have live data / charts. . . since it is a screen-based system that requires monitoring throught the day. Very profitable ! ! ! For more info, email: tradethetrend@sympatico.ca
