The over-the-counter trading market, also known as the counter trading market, refers to equity transactions in markets other than stock exchanges. The establishment of an over-the-counter trading market in our country can provide an equity trading platform for millions of companies that cannot meet the listing requirements, which is conducive to the development of small and medium-sized enterprises, and also helps our country to form a multi-level capital market. The English full name is Over-the-CounterMarket, and the Chinese translation is Over-the-CounterMarket.
