I have been trading equities full time for approx 4 years and thinking about trying out the S&P 500 e minis, seeing that my broker offers the service (CyberTrader). So whats the major advance of ES to equity or options? I'm sure that much has to do with the type of trader and goals. I usually like to close flat each day and am PDT. So trading equity as a PDT you have 4 to 1 buying power. It seems to me that ES are very volitle and thus you are making your broker more money than yourself with stop lossess getting taken out quicker. So you have the speculators and hedgers trading the ES, which I think 95% of the traders trading the ES are not hedging. Maybe the ES are just a trading tool for a different personality.
