General guide lines

The WebSocket API leverages the WebSocket protocol to establish a persistent, single TCP connection through an HTTP handshake, enabling the reception of real-time streaming quotes. This API offers the most efficient solution for retrieving instrument quotes from all exchanges during live market hours.

In addition to real-time market information, Firstock WebSocket API also provides live alerts and order updates. To access this seamless stream of data, a WebSocket client library compatible with your preferred programming language is required.

Connect to:

wss://norenapi.thefirstock.com/NorenWSTP/

Note

• As soon as connection is done, a connection request should be sent with User id and login session id.
• All input and output messages will be in json format.

Multi WebSocket:

    if message.get('s') == 'OK':
        client.subscribe_feed('NSE|26000#NSE|26009#NSE|22')

@ws.on_message(MessageTopic.SUBSCRIBE_FEED)
