There are certainly similarities - both require discipline and good money management skills to succeed in the long run. Also, both are essentially probabilty based, so short term results are often a result of good or bad luck rather than good or bad decision making - if you make a stupid trade, but profit, you still made a bad decision, same goes for playing a rubbish hand, but winning. Similarly, if you put your money in with a good hand, but someone makes a stupid call and gets lucky, that's a good decision by you - in the long run, that kind of situation will make you money over a decent sample size - if you put on a trade which perfectly meets your criteria (which you've tested and found to be profitable over a long period of time), then there's a terrorist attack or natural disaster which causes a crash, and so a losing trade for you, that was still a good decision - you've no way of forseeing that kind of thing, and in the long run, following a profitable plan will make money.
Summary - obviously trading and poker are different, but the psychological elements - freedom from outcome bias etc. are similar, and since a lot of new traders struggle with this, you certainly have a head start. There's still a lot of work required to become profitable though!
As for bluffing, true that it doesn't come into most trading, but what about tricks that scalpers play on the order book - flipping and that sort of thing, which seeks to directly exploit other traders, rather than just "predicting" a move and taking advantage?
