Opening of Data stream does not work anymore

Hi everyone,

I have been trying to get started on recovering live data from Eikon.

In order to do this, after I have tried replicating the code provided on the Refinitiv website concerning the live-streaming. (https://developers.refinitiv.com/eikon-apis/eikon-data-api/learning?content=81721&type=learning_material_item)

After a few trials of opening and closing the price stream (which by the way did not return anything...), it now seems that the opening/closing of the stream does not work anymore at all.

Is there a way to troubleshoot the connection in order to know where the problem is coming from?

Hi @adrien.weihs

Are you on Eikon free trial?

I think it may be related.

Hi @adrien.weihs

Can you expand on what you mean when you say:

After a few trials of opening and closing the price stream (which by the way did not return anything...) - if it did not return anything how did you confirm the open/close was working?
opening/closing of the stream does not work anymore at all - please expand how this differs from the earlier statement.

you can also try and set the log level e.g.

import logging.config
....
....
ek.set_log_level(logging.DEBUG)
ek.set_app_key('your app key')

and share the output (after removing the application ID, access token etc)

Dear Umer,

Thank you for the prompt answer. Please find the output attached above (would this be the optimal way of sharing it with you?)

Concerning the questions:

'if it did not return anything how did you confirm the open/close was working?' - What I meant to say is that although nothing was returned, my Python script was able to end/run both .open() and .close() statements. (I assume that if nothing changes while the stream is open, nothing is returned... why it did not work for me is another issue )

'please expand how this differs from the earlier statement.' - Now, I don't get to the .close() statement anymore, as if it got stuck in the .open() function somewhere.

Hi @adrien.weihs

I saw a reply which stated that it was working for some instruments and not others. However, the post is not appearing on here. So, I am guessing it is more a case of it works sometimes and not others regardless of the instrument - is this correct?

I can see from the log output that there is a disconnect occuring between the library and the Eikon instance. It would appear that the internal Websocket server on the Eikon instance disconnected your python app. Can you confirm if Eikon is working and running correctly?

Also, just to be sure that you uninstalled any previous version of the Eikon python library before installed the EAP 1.1.2b0 in PyPi version?

adrien.weihs

Indeed, I tried multiple combinations of instruments and it did not really seem to matter..

As you said, I noticed the connection error as well... Eikon is running well as far as I can see: is there maybe something to check there?

And yes, I did uninstall Eikon (prior to installing 1.1.2b0).

Hi,

Could you share all the script you are running without any personal Id and pwd, then it'll be easier to analyze and understand what is your issue.

adrien.weihs

Hi @pierre.faurel, please find the script attached. It is mostly the code found on the refinitiv website anyways... (I could not attach the .py file)

script.txt

adrien.weihs

Please also look at the output I attached above (not the same instruments, but same error : [WebSocket 0 96160] Unlock login_event for streaming session 1 due to disconnect event )

Thanks for the script.

I run it with both eikon 1.1.2b0 and 1.1.2b1 version, and I don't reproduce your issue:

I suspect your Eikon product wasn't upgrade to the right version OR you loose credentials to use Eikon API.
That'll explain following trace:
[WebSocket 0 71796] Unlock login_event for streaming session 1 due to disconnect event
[MainThread 96900] Streaming failed to start

Could detail your Eikon APPS versions ?

Hi @pierre.faurel, Thanks for looking into the issue.

I am not sure to understand what you mean by ' you loose credentials to use Eikon API. ' but please find attached the app versions.

app versions.txt

I don't see obvious root cause to your issue.

Let me suggest to clean your Python site-packages directory by deleting manually all subdirectories starting with eikon (sometimes, there is mismatch between different previous versions)

Hi,

I am indeed... I was wondering whether or not this was having an influence on the connection, but I was not able to source this information. Is there a way to confirm it so that I can be in touch with the sales representative?

Hi @adrien.weihs

I think realtime streaming information that you tried to subscribe to is fee-liable so you may not be able to subscribe to that data.

Can you try some FX RIC such as EUR= ?

I do not know if it is going to work but from my understanding, FX RIC is non-fee liable.

I think for account permission, it is better to contact the sales representative.
