This single question seems to be at the heart of both success and failure as a trader. I'm curious as to what others use as their measuring rod for success. Is it accuracy, net ROI per trade, a positive MFE/MAE ratio, not getting stopped out, leaving a certain % of pips on the table in each position held, etc. etc., etc. How do you define it? When you look in the mirror in the morning and say to yourself: 'You know something, you are a successful trader," what does that mean exactly? Define: Successful Trader.
