Struggling to connect via Python using a demo IG account

[33isgreat]

Hello all,
As per the title suggests, I am trying to use the IG API to stream some data, and am struggling with it.
The topic came up before, but some of the posts are quite old. I have tried some github sharing python code samples found online, but I have not been able to successfully connect with any of them.

I also tried to post directly in my browser with "https://demo-apd.marketdatasystems.com/lightstreamer/create_session.txt?LS_user=XXXXXX&LS_password=CST-YYYYYYYYYYY|XST-ZZZZZZZZZZ&LS_adapter_set=DEFAULT" (with my details now removed)


I am getting:
OK
SessionId:XXXXXXXXXXXXXXXXXXXXXXX
ControlAddress:apd144f.marketdatasystems.com
KeepaliveMillis:5000
MaxBandwidth:0.0

Hi,

Please could you share some more information about the problem you got with the Python client you have tested?
I.e. whether you are able to open a client session or not or only the data streaming is not working.
Could you enable library logging (https://sdk.lightstreamer.com/ls-pyt...o.html#logging)?
Additionally, please keep in mind any potential constraints related to the versions supported by IG, which you can check here: https://lightstreamer.com/share/ig/index.html

Regards,
Giuseppe

Hello Giuseppe. Thanks for the response. I just came across https://trading-ig.readthedocs.io/en/latest/ which solved my issue. Take care. M

Dear M / 33isgreat,

would you mind sharing how the trading-ig library helped?

I am running into the same issue: Connecting to the IG lightstreamer server works via http (tested via curl), but not when using the lightstreamer python package. For both, connecting via the trading_ig wrapper or using the `from lightstreamer.client import LightstreamerClient` directly, I always end up with this:

```
2024-01-03 16:25:05.179955|ERROR|lightstreamer.session|Thread-3 (_hx_local_2)|Retrying c
onnection in 3878.010208005435ms. Cause: HTTP error
```

@Guiseppe: Is there a way to increase the verbosity of the logging for the python client in order to debug what is causing this HTTP error?


Many thanks and best regards,
Matthias

Hi Matthias,

Which version of the Python client lib are you using?
With latest version the instructions to activate the debug logging are these: https://sdk.lightstreamer.com/ls-pyt...o.html#logging
