It's better to be pissed about missing out on a huge run than to take the chance of getting stuck with a huge loss IMO At least now you still have funds ready for the next run (probably tomorrow) I think most that get wiped out and end up quitting are those that get too greedy I downloaded a book onto my iPad to read while down here which talks a lot about selling by Dr Alexander Elder "the new sell and sell short" Basically entirely about the psychology of selling I like his books as he can be quite blunt (like yak)
