b1s2,
i'm glad to hear you say get up and walk out is the right way to go. i do that fairly frequently. it keeps me from overtrading. i think overtrading is the way to lose money. in analyzing my trades, this is what i've found. most of my losers are from lacking patience, but a few are from holding out too long. walking away and having a stop in place that's reasonable for your risk level is the way to avoid both scenarios.
i mention this b/c i saw another trader blast someone who gave the same advice (i.e. just walk away) before. this blaster trader frequents this thread, so i hope he knows i'm talking about him.
as long as you have a stop in place to guard against the unforeseen, i think walking away is a good idea.
