References for Using LSEG Data Library with Local Platform Session (ADS/DACS)

HarveySaldana

Hi team. Raising this question on behalf of an external client (Brian Paul from The Capital Group Companies, Inc)

How can get references to utilize the Data Library for Python where I can use a platform session where we have our own LSEG local platform (IP of Local server and DACS username/AppID)

Thank you for reaching out to us.

The LSEG Data Library for Python can be used to real-time stream data from RTDS through the platform.deployed session. The examples are available on GitHub. The client needs to modify the configuration to use the platform.deployed session.

    "sessions": {

        "default": "platform.deployed",

Then, configure the IP and username. For example:

        "deployed": {
            "app-key": "",
            "realtime-distribution-system": {
                "url" : "192.168.42.195:15000",
                "dacs" : {
                    "username" : "api",
                    "application-id" : 256,
                    "position" : ""
                }
            }
        }

The library uses WebSocket to connect to RTDS and the default TCP port for WebSocket connections on RTDS is 15000.

RTDS can provide real-time streaming data so the client can run the code in the 2.02-Pricing examples.
