What does OBM do in the trading platform?

• A. Matches orders and quotes
• B. Manages settlements
• C. Provides real-time news
• D. Generates market indices

Answer: (A)

The function being tested is how trades are created from user intentions. In a trading platform, OBM handles matching—taking incoming buy and sell orders and quotes, placing them into the order book, and driving the matching engine to pair compatible orders. When a match is found, a trade is executed, the order book is updated, and trade details are recorded. It enforces price-time priority (best prices first, and earlier orders take precedence when prices are equal) and supports partial fills, updating or removing orders as fills occur. Other tasks like settling trades, delivering news, or generating market indices are handled by separate components, not by the OBM.
