No. The most important dynamics of poker are about intimidating opposing players to making a mistake. That is, "betting in position" and/or intimidating with your big stack if you've got it. That is.... you try to bluff opponents off of a winning hand or suck them into calling/raising when they have the loser. (And then there's the play when you bluff while stepping into the lion's den.)
Sometimes it ends up being all about 50-50, but none of which translates to the financial markets.
Any trader who hopes to gain some insight into the markets via poker knowledge is fish'n in a dry hole.
