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

Hi @Javajp @vishant @whemant @Kiran @Narendra_Javvadi @vrkhyd @zubuco @N399438

@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.

@sathyaraj
We can fix this error by updating _on_close method with additional arguments in SmartWebSocketV2.py file.

def _on_close(self, wsapp**, close_status_code, close_msg**):

<Error: SmartWebSocketV2._on_close() takes 2 positional arguments but 4 were given>
This error is thrown because on_close method of websocket class takes multiple arguments which are missing in SmartWebSocket library. Example code:

Hi @jaideep-siddula , I'm also having the same issue, have you found the solution?

DiljotSingh11

@jaideep-siddula @DIYD57519, I'm also getting "attempting to resubscibe/reconnect", is there any solution, as I've drilled a bit and got Handshake status 404 not found.
