Which data type includes bid, offer, trade and volume, Level 1 and Level 2 data, and real-time quote data?

• A. Real-time quote data only
• B. Level 1 data and end-of-day values
• C. Bid, offer, trade and volume, Level 1 and Level 2 data, real-time quote data
• D. Historical end-of-day summaries

Answer: (C)

The concept here is real-time market data—the live feed that covers all aspects of active trading activity. This data type includes bid and offer quotes, trade executions with their volume, as well as Level 1 and Level 2 information, delivered in real time. Level 1 shows the best bid and ask, the last traded price, and volume; Level 2 expands that to market depth with additional quotes beyond the best bid/ask. Real-time quote data refers to streaming, up-to-the-moment quotes, and when combined with trades, volume, and depth, you get the full, real-time market data feed. The other options are narrower: real-time quotes alone omit trades and depth; Level 1 with end-of-day values and historical end-of-day summaries are not live and lack depth or real-time trade data.
