Hi @VFM ,

Looking through the Developer Portal, I found the article 'Migrating COM API calls to Python'; while it does not answer your question directly, it has a lot of information you may be after. Namely:

rd.get_data:

realTimeImage = rd.get_data(
    universe=['GBP=', 'EUR=', 'JPY='],
    fields=['BID', 'ASK'])

rd.open_pricing_stream:

def display_data(data, instrument, stream):
    clear_output(wait=True)
    current_time = datetime.datetime.now().time()
    print(current_time, "- Data received for", instrument)
    display(data)
stream = rd.open_pricing_stream(
    universe=['GBP=', 'EUR=', 'JPY='],
    fields=['BID', 'ASK'],
    on_data=display_data
)
stream.open()

stream.close()

and rd.get_history:

FTSEConstituentDf1 = rd.get_data(
    universe=['0#.FTSE'],
    fields=['TR.TURNOVER.timestamp', 'TR.TURNOVER', 'TR.EVToSales'])

FTSEConstituents = list(FTSEConstituentDf1['Instrument'])

IntradayTimeSeriesDf2 = rd.get_history(
    universe=FTSEConstituents,
    fields=['TRDPRC_1'],
    interval="10min", # The consolidation interval. Supported intervals are: tick, tas, taq, minute, 1min, 5min, 10min, 30min, 60min, hourly, 1h, daily, 1d, 1D, 7D, 7d, weekly, 1W, monthly, 1M, quarterly, 3M, 6M, yearly, 1Y.
    start="2022-06-01T13:00:00",
    end="2022-06-01T16:00:00")
 
IntradayTimeSeriesDf2

Are those the calls you were after?

Hi Jonathan,

Can you explain to me what is the difference between the refinitiv.data and refinitiv.dataplatform API? We used the Refinitiv Data Plaform API version 1.0.0a10 till now. The problem is that we want to transfer away from real time pricing to snapshots. (And want an option to retrieve historical rates).

So currently I have this:

pricing = rdp.StreamingPrices(session=session,

universe=df_rics['RIC'].dropna().tolist(),

fields=df_fids['FID'].dropna().tolist()

)

pricing.open()

pricing.get_snapshot()

pricing.close()

This is not what we want - as we are basicly still using streaming prices.

Hi,

After consultation with the team, we understand that we need to use Refinitiv Data library. Trying to install the refinitiv data library we do encounter some problems:

So coming from refinitiv-dataplatform==1.0.0a10

First we installed Refintiv Data version 1.3.1

First we had an error: no module named simplejson.

We installed simplejson seperate.

Then we found that httpx delivered with the wheel for Refinitiv Data is version 0.19 while Refintiv Data required a higher version.

We installed httpx-0.24 manually

Next we got the error "module 'httpcore' has no attribute 'ConnectionPool'

We installed httpcore 0.17.3 manually

Now again we run into problems:

import refinitiv.data as rd

> Exception has occured: module 'h11' has no attribute 'Event'

Can you please check and let us know the correct way to install Refinitiv Data Library for Python under windows?

Hi @VFM ,

Have you had a chance to look into the RD Library for Python - Quick start guide that shows installation steps

Hello @VFM

Are you using Python or Anaconda/Miniconda distribution?

I suggest you create a new Python environment, and try "pip install refinitiv-data" in that environment again.

If you are using Python:
