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

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

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.
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.

Hi @asho and @vrkhyd if anyone of you can provide any help on this? Thanks.

@vrkhyd https://github.com/markov404/AngelOneOptionChainSmartApi
You can user this script it is getting data about OPTIDX every 3 min then saving and updating. You can change the way of saving , it describes in readme.

@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

krunal96

Is websocket 2.0 working? As i am getting only ping data(subscribing to Options). @admin @rajanprabu @StocksDeveloper @rjbanna

abhinay.j

@admin and team and forum members

Request you to post a final working working Websocket 2.0 code as i am still not able to get any ticks even after doing all the changes discussed above.

Thank you.

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

I am facing the same issue

smitshahfo

@whemant Hi,
send a mail to vemula.ramkishore@gmail.com

dharm

@Ankita do you get any solution on this issue?
If Yes so help me

Linux Smiths

@dharm change the function as following

@staticmethod
def _parse_token_value(binary_packet):
    token = ""
    binary_packet = binary_packet.decode("UTF-8")
    for i in range(len(binary_packet)):
        if binary_packet[i] == '\x00':
            return token
        token += str(binary_packet[i])
    return token

What is total_buy_quantity and total_sell_quantity?
When are they different? I mean whatever is bought is sold as well. Thanks.

Linux Smiths

nvm, I gather that this is the amount of pending buy and sell orders at the Exchange.
