Calculate your GROSS/SHARE by taking the dollar amount you make per month (or use lifetime if you have the data) divided by the total volume you trade. ex. Last month I grossed $3105/340,400 shares = 0.9cents Along the lines of 90% of traders fail, I hear that the best EQUITY traders in the world net approximently 1.0 cents per share. However, this is factoring transaction costs. I like to know how much does everyone gross per share. This is the best way to measure EQUITY trading prowess on a level playing field. For all of you who are futures traders, please don't complain in this tread...just start a new one with a poll that would measure futures performance. Thanks.
