End-of-day data is updated once per day, after the market closes. This is suitable for long-term investors who don’t need real-time price movements.

15-minute delay data provides updates throughout the trading day, but with a slight delay. This is a good option for investors who trade frequently and want to track stock prices during the day but don’t need the most up-to-the-second data.

Real-time data delivers the latest stock prices with minimal delay. Ideal for very active traders who can capitalize from the latest market movements.
