Exploring the Functionality of the Market Data WebSocket

What is the primary focus of the market data-websocket?

The FYERS Market Data WebSocket is built for speed and efficiency—designed to deliver real-time stock market updates with minimal delay. It provides a continuous data stream to help developers and traders stay updated with the latest market activity.

What does the Market Data WebSocket provide?

The primary focus of the Market Data WebSocket is low-latency, real-time access to market data. Once connected, it establishes a persistent, bidirectional channel between the user’s system and FYERS’ servers. This allows:

  • Streaming of live stock prices
  • Tracking of bid/ask quotes
  • Monitoring of trading volumes
  • Access to order book changes (if subscribed)

This tool is ideal for users building trading platforms, bots, or dashboards that rely on fast, up-to-date data for analysis or automation.

FYERS’ WebSocket stream supports selective subscriptions, so you only receive updates for symbols you specify—optimizing bandwidth and app performance.
The WebSocket is not intended for historical data or order management. Use separate FYERS APIs for those functions.
