What you’ll learn

  1. A Market That Matches Buyers and SellersDefine the exchange as a matching venue and explain the order book.Exchanges match bids and offers. The book shows resting interest; market and limit orders trade urgency for price control.
  2. How a Trade Actually HappensWalk through match, report, clear, settle and related market roles.Executions print quickly; clearing and settlement finish the transfer. Brokers, makers, and multi-venue structure surround the engine.
  3. What an Exchange Is NotSeparate price discovery, halts, and indexes from guarantees or advice.Exchanges discover prices under rules; they do not guarantee value. Halts pause extremes. Indexes are scoreboards, not venues.
