- interdealer brokers
- Also known as IDBs. Dresdner Kleinwort Wasserstein financial glossaryStock Exchange member firms who act as intermediaries for anonymous trading between market makers. When a market maker wishes to complete a large trade, he may advertise the trade through an IDB. Another market maker may take the other side of the bargain. The deal is anonymous, with neither market maker knowing who is completing the other side of the trade. This is achieved by having the market makers dealing with the IDB as a principal, rather than as an agent between the two final participants. Dresdner Kleinwort Wasserstein financial glossary
