Which type of market data allows traders to see both live prices and analyze market trends?

Real-time data is essential for traders as it provides live prices and allows them to analyze market trends effectively. This type of market data is delivered instantly, enabling traders to react promptly to price changes, execute trades, and make informed decisions based on the most current market conditions. The immediacy of real-time data is crucial in fast-paced trading environments where prices can fluctuate rapidly.

Other types of data, such as delayed data, provide information that is not current and may reflect past prices, while snapshot data offers a brief view of the market at a specific moment in time without ongoing updates. Market data is a broader term that encompasses various types of data inputs, but it does not specifically denote the immediacy or continuous updates that real-time data does. Thus, real-time data is the most appropriate choice for traders looking to maintain an up-to-date understanding of market movements and trends.
