Explain about the in-quote-driven according to trade intermediation.
In quote-driven dealer markets, a market-maker or dealer is onto one side of each trade. (Remember that dealers are also termed as market makers, like they quote prices and stand prepares to buy and sell at such quotes, therefore they give liquidity). Dealers include an inventory of the security that fluctuates as they trade. They profit by charging a bid-ask spread and by speculating.
