I trade the S&P emini (ES) and have made money on 84% of my trades for the year. I am not a novice in trading. However, I continue to make the same stupid mistake of moving my stop loss order to offset my position whenever the market moves against me. For instance, on Friday I had a 4 point stop loss on my long ES position and it turned into a 16 point loss. I keep hoping, begging, praying the market will reverse and breakeven which it only occasionally does. What do traders do to mentally prevent themselves from making this mistake of moving their stop loss order? Any advice would be appreciated.
