Was just thinking about it this.. Is a mechanical stop loss for someone who cannot discipline themselves to the point of pulling the plug, accepting defeat, or identifying when they have lost in the heat of the battle? It is so much easier to just be forced out of the fight by something you already had in place. Am I completely wrong? In my opinion when it comes to stop losses, there are 3 tiers of traders. 1 - The bad trader who doesn't use a stop loss but rather the "pray" method 2 - The good trader who uses mechanical stop loss - I'm out no matter what 3 - The great trader who can consistently use discretionary stop loss - I'll think about getting out, but see what develops Or does the good trader eventually evolve into the great trader, who doesn't need the hand-holding that a mechanical stop loss offers. Maybe it comes to down 1 mans stop is another mans double down, etc. and appetite for risk. Just a thought.
