how does one use an otc market 
trading on an otc market is similar to trading on a centralized market traders find a broker who serves as the middleman between them and fellow dealers as well as with corporations and businesses that are not being traded on centralized stock exchanges one of the primary differences between an otc market and an exchange market is that on an otc market the brokers have more flexibility on the buy and sell prices that they set as a result a broker may quote one price to one client and a different price to another and there may be differences in the bid ask spread
