Python example that uses the Refinitiv Websocket interface to facilitate the consumption of realtime data. This example is meant to be a simplistic version of the 'rmdstestclient' tool and illustrates a variety of scenarios such as:
- EDP or ADS connection
- Batch / View Request
- Streaming / Snapshot
- Reuters Domain Models
The source code presented in this project has been written by Refinitiv solely for the purpose of illustrating the concepts of using the Websocket interface. None of the code has been tested for a usage in production environments.

pip install -r requirements.txt
- Run the following (which installs 'requests' and 'websocket-client'):
- Login Credentials
- You will need the following:
- To Login to an ADS server
- the hostname/ip + port number of the ADS
- DACS username
- For EDP connection
- EDP server data url
- EDP Authentication server url
- Your EDP username and password
- To Login to an ADS server
- You will need the following:

Below are a few example scenarios with sample arguments
Connect to EDP, request MarketPrice items from default service and display summary stats
-H emea-1.pricing.streaming.edp.thomsonreuters.com -p 443 -items VOD.L,BT.L -u <EDP Username> -pw <EDP Password>
Connect to ADS, request MarketPrice items from ELEKTRON_DD service and display summary stats
-S ELEKTRON_DD -H ads1 -items VOD.L,MSFT.O,TRI.N -u umer.nalla
Connect to ADS, request MarketPrice items from default service and display summary stats
-H ads1 -items VOD.L,MSFT.O,TRI.N -u umer.nalla
As above and display received data
-H ads1 -items VOD.L,MSFT.O,TRI.N -u umer.nalla -X
As above with output redirected to file log.out
-H ads1 -items VOD.L,MSFT.O,TRI.N -u umer.nalla -X -l log.out
As above except request MarketByPrice data
-H ads1 -md MarketByPrice -items VOD.L,BT.L,BP.L -u umer.nalla -X -l log.out
As above except using numeric Domain value
-H ads1 -md 8 -items VOD.L,BT.L,BP.L -u umer.nalla -X -l log.out
MarketPrice request for RICs read from file srics.txt (one RIC per line)
-H ads1 -f srics.txt -u umer.nalla -X -l log.out
MarketPrice View (FIDs TRDPRC_1,BID,ASK) request for RICs read from file srics.txt
-H ads1 -f srics.txt -vfids 6,22,25 -u umer.nalla -X -l log.out
MarketByOrder request for RICs read from file srics.txt (one RIC per line)
-H ads1 -f srics.txt -md MarketByOrder -u umer.nalla -X -l log.out
As above except mixed Domain RICs read from file extrics.txt (numeric domain|RIC per line)
-H ads1 -ef extrics.txt -u umer.nalla -X -l log.out
