Hi @ajith.n.namboothiri.uy30abqu

Please share your code so that I can check from my side

I shared the code, looks like it was deleted. The exact error is : AttributeError: partially initialized module ‘fyers_apiv3.FyersWebsocket.data_ws’ has no attribute ‘FyersDataSocket’ (most likely due to a circular import) This happens on the sample code in Response Attributes(Market Data Update) available in API v3 documentation

from fyers_apiv3.FyersWebsocket import data_ws


def onmessage(message):

    print("Response:", message)


def onerror(message):

    print("Error:", message)


def onclose(message):

    print("Connection closed:", message)


def onopen():

    data_type = "SymbolUpdate"

    # Subscribe to the specified symbols and data type
    symbols = ["NSE:NIFTY50-INDEX" , "NSE:NIFTYBANK-INDEX"]
    fyers.subscribe(symbols=symbols, data_type=data_type)

    # Keep the socket running to receive real-time data
    fyers.keep_running()


# Replace the sample access token with your actual access token obtained from Fyers
with open("access.txt","r") as r:
    access_token = r.read()
client_id = 'XXXXX'
new_token = f"{client_id}:{access_token}  "

# Create a FyersDataSocket instance with the provided parameters
fyers = data_ws.FyersDataSocket(
    access_token=new_token,       # Access token in the format "appid:accesstoken"
    log_path="",                     # Path to save logs. Leave empty to auto-create logs in the current directory.
    litemode=False,                  # Lite mode disabled. Set to True if you want a lite response.
    write_to_file=False,              # Save response in a log file instead of printing it.
    reconnect=True,                  # Enable auto-reconnection to WebSocket on disconnection.
    on_connect=onopen,               # Callback function to subscribe to data upon connection.
    on_close=onclose,                # Callback function to handle WebSocket connection close events.
    on_error=onerror,                # Callback function to handle WebSocket errors.
    on_message=onmessage             # Callback function to handle incoming messages from the WebSocket.
)

# Establish a connection to the Fyers WebSocket
fyers.connect()

when I changed fyers object to wfyers, it worked. Thank you
