We would like to make this thread as a platform to share experiences and thoughts about Expectancy based trading systems. I will appreciate if Admin would help us keep focused on this specific topic. We can even make this an educational forum for those traders who are not familiar with the many concepts associated with Expectancy. Of course there is plenty of literature available on the web and in the books on this topic. In my experience, a key metric to measure the performance of a trading system is its Expectancy. Personally, I like to use Expectancy as a % per month. It has helped me design a trading system which has now evolved to a point been where it is stable and cosistently profitable for the past year and has endured a highly volatile market cycle. How about you?
