After fuckin around in options for 10 years I am dipping my toe into trading the ES (I started a thread about a week and half ago re my first foray) Question - I am not a statistics major and I would like to find out some basic confidence levels. After 100 trades what confidence level does the results bode for future trades? (I hope you know what I am getting at) Or, what # samples correspond to common confidence levels? 20? 50? 100? 200? 300? 500? 1000? IOW, if I average X per trade in a 100 trade run, how confident should I be in that average continuing over say 2000 trades? Any help greatly appreciated. Still trading options but sometimes not liquid enough.
