Websocket data fetchiong error

[suyeshs]

I am getting the below Error when connecting to the WebSocket using Python. Connection is successful.

exchange_quotes_token, market_depth_token = self.get_stock_token_value(exchange_code=exchange_code, stock_code=stock_code, product_type=product_type, expiry_date=expiry_date, strike_price=strike_price, right=right, get_exchange_quotes=get_exchange_quotes, get_market_depth=get_market_depth)

getting this error since past 10 days,

using the code below.

breeze = BreezeConnect(api_key=api_key) breeze.generate_session(api_secret=api_secret, session_token=session_token)

breeze.ws_connect() sleep(2)

def on_ticks(tick): print("Ticks: {}".format(tick))

Assign the callbacks.

breeze.on_ticks = on_ticks

breeze.subscribe_feeds( exchange_code="NFO", stock_code="CNXBAN", product_type="options", expiry_date="11-Oct-2023", strike_price="45000", right="call", get_exchange_quotes=True, get_market_depth=False, )

today getting the above errors....anyone with fix for this

[axresh]

Yes, faced this problem today, now its working... What was the issue?

[sanchaykasturey]

I have also faced this error, this is stupid but this is supposed to accept specific date time formats for everything like while subscribing to option feed, while fetching option chain, etc.

So, for your reference below is the kind of format which works:

expiryOpt="2023-12-22T06:00:00.000Z" this is DATE for the expiry of the Option
subscribeOpt= "22-Dec-2023" #this is DATE for subscribing the OHLCV of the Option
expiryFut="2023-12-22T06:00:00.000Z" #this is DATE for the expiry of the FUTURE

Also if you don't require tick by tick data, you may use: interval: "1minute" for 1 minute data

Anyone got the Solution. This subscribe_feeds work with NSE as exchnage_code but fails for NFO stating concatenation error

subscribe stocks feeds

breeze.subscribe_feeds(exchange_code="NFO", stock_code="ZEEENT", product_type="options", expiry_date="28-Dec-2023", strike_price="350", right="Call", interval="", get_exchange_quotes=True, get_market_depth=False)
