I think this is one of the biggest "diseases" traders have. A stop loss is like a red light, it's not a suggestion. It tells you to get out of the market not to add more money to the trade. It simply makes me angry to see people adding money to a losing position. It has no justification except one. HOPE! They don’t say "gee, I was wrong and should have exited in my stop loss level", they say "I am correct about the direction of the market, it's just that my stop loss was placed to close to my entry. If I hang in there and add more money the trade will surely go my way and I will not only make for the loss but I will make much more since now I am adding to my position at a much better price!".
