Dealer

The casino employee who staffs the games offered.

Dealers, or principals, buy and sell securities for their own accounts, adding liquidity to the marketplace and seeking to profit from the spread between the prices at which they buy and sell.

In the over-the-counter market, in most cases, it is dealers - also called market makers - who provide the bid and ask quotes you see when you look up the price of a security.

Those dealers are willing to commit their capital to specific securities and are ready to trade the securities at the quoted prices.

this is a person who works for the casino at the game.

The player in a poker game who actually (or theoretically) is dealing the cards. When a professional dealer (casino or cardroom) or automated dealer (online) is present - it is necessary to identify the player who would be dealing the cards because the blinds and the betting action are to the left of the dealer. This is done by utilizing a marker called a dealer button which travels around the table in a clockwise manner, moving to the next player after each hand is completed.
