Venues and Intermediaries

Market-venue terms for exchanges, brokers, market makers, clearing systems, OTC venues, and trade-execution infrastructure.

Venues and intermediaries explain who stands between buyers and sellers, where orders meet, and which infrastructure completes trades after execution.

Use Organized Exchanges and Market Venue Basics for broad exchange concepts, then use the regional exchange branches for U.S., European, Asia-Pacific, Canadian, and other global venues.

Execution mechanics are separated from venue directories. Broker-Dealers and Market Makers covers intermediaries, Clearing, Settlement, and Transfer Infrastructure covers post-trade plumbing, and Trading Systems and Market Quality covers quote, transparency, and execution-system terms.

Alternative venues such as dark pools, pink markets, and MTFs now live under OTC, Dark Pools, and Alternative Trading Systems, while futures, options, commodity, and swap venues live under Derivatives and Commodity Venues.
