over-the-counter - Investment & Finance Definition
A trading market that isn’t part of an exchange or a formal, regulated market. The OTC market is unregulated, and parties interact directly with each other, creating transactions with terms that are mutually agreeable (as long as they are allowed by law). In the foreign exchange market, the OTC market also is called the inter-bank market.
