How are financial trades made in an over the counter market?
On the contrary to the organized exchanges that have physical locations, the over the counter market contain no fixed location, or more accurately, it is everywhere. The over the counter market, or OTC, is network of dealers about the world who maintain inventories of securities for sale. If you desired to buy a security i.e. traded OTC, you would call your broker, who would then shop amongst competing dealers who contain the security in their inventory. After locating the dealer along with the best price, your broker would buy the security on your behalf.
