    @Ashok ok Thank you.

    Sometimes its printing the same message. multiple times. does it mean no response from server.

    @vrkhyd You will get one in every 30 seconds.
    Are you getting tick data ?

    @admin
    There are 2 issues in your new websocket 2.0, we have been raising this question but no one is responding.

    1. we are getting "Socket object has no attribute pending when requesting the data at the line self.wsapp.send(json.dumps(request_data)). All my authenication is successful, why I am getting this error.

    2. fetching order_book is dead slow in angel, so I tried to implement fetch from websocket order_feed, but I think this order_feed is not implmented yet in your websocket2.0 and your websocket1.0, the order_feed is not at all fetching the order details data.
      Resolve these errors, I think you guys need to have solid testing team. you cannot roll a beta version directly to prodution (live market) targetting clients and withdrawing the earlier versions. Make the product stable. Dont experiment... If this continues. soon Angel will loose lot of customer base.

    Hi @vrkhyd,

    I am getting data in below format:

    {'subscription_mode': 3, 'exchange_type': 5, 'token': '246083', 'sequence_number': 2414112, 'exchange_timestamp': 1674818721000, 'last_traded_price': 672400, 'subscription_mode_val': 'SNAP_QUOTE', 'last_traded_quantity': 1, 'average_traded_price': 667360, 'volume_trade_for_the_day': 8589, 'total_buy_quantity': 644.0, 'total_sell_quantity': 384.0, 'open_price_of_the_day': 661700, 'high_price_of_the_day': 672700, 'low_price_of_the_day': 661700, 'closed_price': 653300, 'last_traded_timestamp': 1674818717, 'open_interest': 535600, 'open_interest_change_percentage': -4627489742054556454, 'upper_circuit_limit': 679400, 'lower_circuit_limit': 627200, '52_week_high_price': 678100, '52_week_low_price': 599400, 'best_5_buy_data': [{'flag': 0, 'quantity': 7, 'price': 672600, 'no of orders': 6}, {'flag': 0, 'quantity': 14, 'price': 672700, 'no of orders': 12}, {'flag': 0, 'quantity': 10, 'price': 672800, 'no of orders': 10}, {'flag': 0, 'quantity': 7, 'price': 672900, 'no of orders': 6}, {'flag': 0, 'quantity': 29, 'price': 673000, 'no of orders': 21}], 'best_5_sell_data': [{'flag': 1, 'quantity': 35, 'price': 672400, 'no of orders': 11}, {'flag': 1, 'quantity': 23, 'price': 672300, 'no of orders': 3}, {'flag': 1, 'quantity': 1, 'price': 672200, 'no of orders': 1}, {'flag': 1, 'quantity': 2, 'price': 672100, 'no of orders': 2}, {'flag': 1, 'quantity': 12, 'price': 672000, 'no of orders': 4}]}

    Please could explain how you are converting this data in to get 1 min candlestick data? If you could share your code that will be of great help. Thanks.

    @admin, the instructions for websocket2.0 seems to be too lengthy, Kindly consider to simplify & add sample like we have it in https://github.com/angel-one/smartapi-python🙏

    How to handle ws disconnection?
    Do we need to Initialize ws again or it handles reconnection?
    I am getting the following error sometimes

    ERROR - Handshake status 429 Too Many Requests - goodbye
    ERROR - error from callback <bound method SmartWebSocketV2._on_close of <SmartWebsocketv2.SmartWebSocketV2 object at 0x000001D5D1637750>>: SmartWebSocketV2._on_close() takes 2 positional arguments but 4 were given

    This script i not working. No error, nothing happens, It times out. Why ?
    I have tried many a times today.

    Code below:

    from SmartApi.smartWebSocketV2 import SmartWebSocketV2
    from smartapi import SmartConnect
    import pyotp

    obj=SmartConnect(api_key="") # feed app API key.
    #optional
    #access_token = "your access token",
    #refresh_token = "your refresh_token")
    #login api call
    token='    '

    Login needs to be done through MPIN now.

    data = obj.generateSession("","",pyotp.TOTP(token).now())
    print(data)
    refreshToken= data['data']['refreshToken']
    jwt_token = data['data']['jwtToken']

    	#fetch the feedtoken

    feedToken=obj.getfeedToken()

    AUTH_TOKEN = jwt_token
    API_KEY = ******* #feed app API key
    CLIENT_CODE = '*******'
    FEED_TOKEN = feedToken

    correlation_id = "Testing"
    action = 1
    mode = 3

    token_list = [{"exchangeType": 1, "tokens": ["26009","11536","1594","2885"]}]

    sws = SmartWebSocketV2(AUTH_TOKEN, API_KEY, CLIENT_CODE, FEED_TOKEN)

    def on_data(wsapp, message):
    print("Ticks: {}".format(message))

    def on_open(wsapp):
    print("on open")

    sws.subscribe(correlation_id, mode, token_list)

    def on_error(wsapp, error):
    print(error)

    def on_close(wsapp):
    print("Close")

    Assign the callbacks.

    sws.on_open = on_open
    sws.on_data = on_data
    sws.on_error = on_error
    sws.on_close = on_close

    sws.connect()

    Rsult:

    on open
