I just started playing a bit of onine poker again recently. I find that poker shares a lot of similarities with trading/investing. For example, bank roll management is like risk management. Understanding the behaviour of the table (aggressive, conservative, loose, tight) is similar to understand behaviour economics (market fear, greed (I'd rather we have this right now), etc). When to cut your loses or having the patience to wait for the right time is market timing(though much easier in poker). And finally poker tilt is the same as trading.
