An interdealer quotation system (IQS) is a system designed to organize price quotes by brokers and dealer firms. They exist to provide investors with accurate and relevant information about quotes. There are a number of IQSs, and each has its own specialization. For example, in the United States, the Nasdaq, the Nasdaq's SmallCap Market, and its Over-the-counter Bulletin Board (OTCBB) platform are all integrated into the same IQS.
