Refer to the Firstock Connect Documentation for the complete list of supported methods.

WebSockets

The WebSocket architecture has been completely upgraded. You must initialize the WebSocket with a configuration model, define callback methods, and then call subscribe() / unsubscribe() on the active connection.

Import from firstock import firstock

1. Define Your Callback Methods

These functions will receive real-time streaming data and are fully customizable.

def on_connection(conn): # Save the connection for future subscribe/unsubscribe global ws_conn ws_conn = conn

def on_subscribe_feed(data): print("Feed Data:", data)

def on_option_greeks(data): print("Option Greeks:", data)

def on_order_book(data): print("Order Book:", data)

def on_position_book(data): print("Position Book:", data)

2. Create WebSocket Model model = firstock.WebSocketModel( orderData=on_order_book, positionData=on_position_book, subscribeFeedData=on_subscribe_feed, subscribeOptionGreeksData=on_option_greeks, subscribeFeedTokens=[], subscribeOptionGreeksTokens=["NSE:26000", "BSE:1"], webSocketConnection=on_connection )

3. Initialize WebSocket err = firstock.initializeWebSocket(userId="{{userId}}", model=model) print("Initialize Error:", err)

4. Subscribe Tokens if ws_conn: err = firstock.subscribe(ws_conn, ["NSE:26000", "BSE:1"]) print("Subscribe Error:", err)

5. Unsubscribe Tokens err = firstock.unsubscribe(ws_conn, ["NSE:26000", "BSE:1", "NSE:2885"]) print("Unsubscribe Error:", err)

6. Close WebSocket err = firstock.closeWebSocket(ws_conn) print("Close Error:", err)

Notes

Tokens can be provided as pipe-separated ("NSE:26000|BSE:1") or list format.

If tokens are not pipe-separated, the library will auto-format them.

Each callback runs on every incoming tick update.

WebSocket supports:

Feed updates

Option Greeks

Order book stream

Position book stream

Changelog

• The Python package has been updated to automatically convert passwords into SHA256 hashes prior to submission to the login URL.

• The package now includes a multi-login feature, enabling simultaneous login for multiple users, with each user's session being individually stored.

• For all APIs, it is now required to pass the userId. The corresponding jKey session linked to the userId will be utilized for executing the API.

• The following methods have been updated to require trading symbols instead of tokens:

  • Get Multi Quotes LTP
  • Get Multi Quotes
  • Day Interval Time Price Series
  • Time Price Series
  • Security Info
  • Get Quotes

• The method for accessing the websocket has been entirely revamped. Detailed information will be available in an upcoming blog post. Additionally, sample code illustrating the new method can be found in the examples section.
