@admin and Team,

I had spent sometime in python SDK to see whats the issue. In the SmartWebSocketV2 file in GitHub (https://github.com/angel-one/smartapi-python/blob/AMX-3393-Smart-Api-Python-Library/SmartApi/smartWebSocketV2.py )

line 310 that is converting byte string to token is not working. If I simply comment it out and give the token number directly it can now print Ticks.

 def _parse_binary_data(self, binary_data):

        try:
            parsed_data = {
                "subscription_mode": self._unpack_data(binary_data, 0, 1, byte_format="B")[0],
                "exchange_type": self._unpack_data(binary_data, 1, 2, byte_format="B")[0],
                #"token": SmartWebSocketV2._parse_token_value(binary_data[2:27]),
                 "token": 234876,
                "sequence_number": self._unpack_data(binary_data, 27, 35, byte_format="q")[0],
                "exchange_timestamp": self._unpack_data(binary_data, 35, 43, byte_format="q")[0],
                "last_traded_price": self._unpack_data(binary_data, 43, 51, byte_format="q")[0]
            }

lines 353 to 360. This functions needs a re look.

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

I could re write the function but I would request the team to have a look .

Try the SDK from angel-one

https://github.com/angel-one/smartapi-python

This resolved some of my order errors.. Although im not sure if this will resolve your issue,,

@chexki

Are you trying to sell your holding ?

Are you using the latest SDK ?

Hello @admin and all,

Did you anyone managed to get Ticks via the new smartWebSocketv2 using python SDK. I only get Pings ans Pongs and no ticks.

on open
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'
In on pong function==> b'\x00'

It would be helpful to get some feedback from people who used it successfully.

Thanks

Hi @admin and Team,

We discovered a major issue today that was nagging us for a while. This never happened before August. We subscribed to Nifty and BankNifty Futures and few more options data ( different strikes ) using web sockets. while ticks for options were coming properly randomly Futures ticks stopped coming. This happened at least dozen times today.

We could get ticks once we restart the script. But this is not anywhere close to being optimal as order being sent around each minute. Please take this as a priory and diagnose whats really the issue.

We are using latest python SDK. Until August everything was stable and we hardly had to intervene. It went downhill from there.
