I overheard the following: One of the traders was telling another his 'opinion' of the cpo futures market, "If you go shot and go away for holiday, when you come back you can cover at huge profits below 2300"

Now what sort of risk parameters govern such an ego based strategy? Stop loss of 100, 200, 300 ticks???

This is why opinions are a fool's game. You should never ask someone else's opinion on the direction of the market, nor should you offer your own opinion to anyone else."
