Unable to stream Epic - Python

[BCC]

Hi everyone,

I'm new in the "dev world"  , and I'm working on building my own app n python. 

For the Rest API, it's OK, I can log and make what I want.

BUT, for the streaming part, I'm completely in the fog! lol

 

I downloaded the excellent "trading-ig" python module (thanks to the devs that made it 👌) but I can't stream epic price.

Here the code I use:

Quote

import logging
import time
from trading_ig import IGService, IGStreamService
from trading_ig.config import config
from trading_ig.streamer.manager import StreamingManager
#from sample.sample_utils import crypto_epics  # fx_epics, index_epics, weekend_epics


def main():
    logging.basicConfig(level=logging.DEBUG)

    ig_service = IGService(
        config.username,
        config.password,
        config.api_key,
        config.acc_type,
        config.acc_number,
    )

    ig = IGStreamService(ig_service)
    ig.create_session(version="3")
    sm = StreamingManager(ig)

    crypto_epics = ['IX.D.NASDAQ.IFD.IP']
    tickers = []
    for epic in crypto_epics:  # fx_epics, index_epics, crypto_epics
        sm.start_tick_subscription(epic)
        tickers.append(sm.ticker(epic))

    for idx in range(0, 10):
        for ticker in tickers:
            print(ticker)
        time.sleep(1)

    sm.stop_subscriptions()


if __name__ == "__main__":
    main()

 

and here the error message:

Maybe it's a little error in the code, but I can't find it !

FYI, I tried with spreadbet and cfd epic (but my demo account is a CFD account).

Thank you for your kind answer 

 

ps: if you have some advice in coding, I take it

Dear @BCC,

Unfortunately, we do not provide coding support. However, you can use our web API companion, which can be found at https://labs.ig.com/. Additionally, some amazing people in our community may be able to assist you.

Thanks,

@BCC are you logging in to a Spread bet or CFD demo account? To stream a CFD epic, you will need to log in with a CFD account. User name, password and API key will be the same as with a spreadbet account - but account ID will be different. Its the 'acc-number' param in trading-ig.

The sample works fine for me with the epic IX.D.NASDAQ.IFD.IP in a CFD demo account, but fails like your snippet when logged into a spread bet account

Thank you for your answer

 

I check, it's a CFD account

@KoketsoIG, It works perfectly with streaming companion

That shows the account that is logged into the REST API companion. What is important is the credentials you are using in the trading-ig library. Check the file trading_ig_config.py in your project, and make sure it is using the correct account details

I checked, this is the good account number.

Hello,

 

I tried to modify the epic (CFD or Spreadbet), and it didn't work

I don't know if it could help, but there are some infos on my config: MacBook Air M2, IDE PyCHarm CE.

Tell me if you need more infos 👍

[BCC]

I tried to modify the trading_ig_config.py, and I have the same message: usually I wouldn't have been able to connect ! But it was OK ! So, I think I don't modify the good file (but I don't find other file in my laptop).

I think it could be a problem with my venv in pycharm.

Can you help to make a Clean install in order to test it again ?

Thank you for your help

Hi guys,

 

I reinstall in a clean venv on Pycharm and ...... IT WORKS!
