You are most likely FAR more knowledgable than I at trading, but from what I've seen and experienced so far over the years (and more notably lately with futures) it seems to share a few basic fundamentals with poker. At least it's a way for me to relate. I don't know if you play much poker but the two matches I see are: - Strong discipline is needed. Need to stick to your system. Your hands (trades) need to be done for a reason. It's all too easy to let emotion get the best of you and if you do you are sunk. - Play very few and only high probability hands (trades) with proper reward ratios (pot odds) and exit strategies. Just how I see it. At the very least it let's me see and hopefully understand how to control emotion and discipline.
