Eikon Python API - ticks received once every 3 sec instead of few ticks in a second

Hello. I am trying to retrieve current prices using the Python example you provided, but getting responds every 3 sec, while in the Eikon I see few ticks every sec.


import eikon as ek

from datetime import datetime



def display_fields(streaming_prices, instrument_name, fields):

print(datetime.now(), " Fields received for", instrument_name, ":", fields)



if __name__ == "__main__":

print("Starting")

ek.set_app_key('xxx)

print("Connected")


streaming = ek.StreamingPrices(

instruments=['EUR='],

service = 'IDN_RDFNTS_CF',

fields=['SALTIM', 'CF_BID', 'CF_ASK', 'OPEN_PRC', 'CF_HIGH', 'CF_LOW', 'CF_CLOSE'],

on_refresh=lambda streaming_prices, instrument_name, fields:

display_fields(streaming_prices, instrument_name, fields),

on_update=lambda streaming_prices, instrument_name, fields:

display_fields(streaming_prices, instrument_name, fields)

)

streaming.open()


while True:

if streaming.state != "Open":

streaming.open()


streaming.close()

Thank you @Umer Nalla for your assistance. After the issue was reviewed by Eikon Technical team, the cause was identified, addressed, and fixed by the Refinitiv Development team and will be released globally soon with Eikon API Proxy version 1.1.0.91.

Hi @oleg.lipshits

The code you are using looks fine, if I use the same code I get updates approx 2-3 times a second e.g.

2020-06-04 10:53:00.439994  Fields received for EUR= : {'CF_BID': 1.1198, 'CF_ASK': 1.1199} 2020-06-04 10:53:00.715981  Fields received for EUR= : {'CF_BID': 1.1196, 'CF_ASK': 1.12} 2020-06-04 10:53:01.060276  Fields received for EUR= : {'CF_BID': 1.1197, 'CF_ASK': 1.12} 2020-06-04 10:53:01.324176  Fields received for EUR= : {'CF_BID': 1.1196, 'CF_ASK': 1.1199} 2020-06-04 10:53:01.612824  Fields received for EUR= : {'CF_BID': 1.1198, 'CF_ASK': 1.1199} 2020-06-04 10:53:01.950824  Fields received for EUR= : {'CF_BID': 1.1197, 'CF_ASK': 1.1201} 2020-06-04 10:53:02.371836  Fields received for EUR= : {'CF_BID': 1.1197, 'CF_ASK': 1.12} 2020-06-04 10:53:02.691826  Fields received for EUR= : {'CF_BID': 1.1197, 'CF_ASK': 1.12} 2020-06-04 10:53:02.981823  Fields received for EUR= : {'CF_BID': 1.1196, 'CF_ASK': 1.12} 2020-06-04 10:53:04.062825  Fields received for EUR= : {'CF_BID': 1.1197, 'CF_ASK': 1.12} 2020-06-04 10:53:04.641828  Fields received for EUR= : {'CF_BID': 1.1196, 'CF_ASK': 1.12}

All I can assume is that your local Eikon install is conflating locally perhaps?

Does the same happen if run in a Jupyter Notebook vs standalone .py script?

I have reached out to some Eikon experts as well - in case they can shed some light on this.

"All I can assume is that your local Eikon install is conflating locally perhaps? "

Can you elaborate?

Can it be some Eikon API preferences?

Hi @oleg.lipshits

Sometimes users are connected to an internal TREP for the realtime data - this seemed unlikely given the service name but I wanted to check. A colleague has checked and you are using a hosted connection (i.e. internet) so that is not the case.

As another test, can you please remove all the following block of code

streaming.open()
while True:
    if streaming.state != "Open":
        streaming.open()
streaming.close()

and replace with the following code:

streaming.open()
asyncio.get_event_loop().run_until_complete(asyncio.sleep(180))
streaming.close()

you will, of course, need to import asyncio

If that does not help - just for testing purposes, please try the following changes to your StreamingPrice request and see if you get more frequent updates?:

...
    instruments=['EUR='],
    service = 'IDN_RDF',
    fields=['BID', 'ASK'],
....

Please report back with the results of both the above tests so we can try and assist further.

If both the above changes make no difference to the outcome, please upload a txt file containing the console output from the script for a few minutes of runtime.

Thanks.
