Conflate data

tboonte

Hello,

I am currently using C# to get market data and wondering whether the data is being conflated from the server (3 update per second?)

Below is snippet of my LSEG.Ema.Access.RequestMsg

        private static RequestMsg CreateEquityRequestMsg(InstrumentSymbol instrumentSymbol)

        {

            var fieldArray = new OmmArray();

            fieldArray.AddInt(6);     // LAST_PRICE

            fieldArray.AddInt(22);    // BID

            fieldArray.AddInt(30);    // BID_SIZE

            fieldArray.AddInt(25);    // ASK

            fieldArray.AddInt(31);    // ASK_SIZE

            fieldArray.AddInt(3372);    // OFF_CLOSE vs 21 HST_CLOSE

            fieldArray.AddInt(3855);  // QUOTIM_MS

            fieldArray.Complete();


            var payload = new ElementList()

                .AddUInt(EmaRdm.ENAME_VIEW_TYPE, 1)

                .AddArray(EmaRdm.ENAME_VIEW_DATA, fieldArray)

                .Complete();


            var request = new RequestMsg()

                .ServiceName("ELEKTRON_DD")

                .Name(instrumentSymbol.Ric)

                .Payload(payload)

                .InterestAfterRefresh(true);


            return request;

        }

If it's not conflated, can you please show me how to configure it?

Thank you.

Hello @tboonte

Please be informed that the conflation is setting on the Server Side (RTO, on-prem ADS, RTMDS, etc). The API cannot configure or change this server setting.

If you are connecting to the RTO, it is most likely to be a conflate data by default.

You can check incoming data QOS from the Refresh Response message.

Example Data from RTO:

You can find more detail about this QoS parameter on the RDM Usage guide document of the EMA C# Documents (available in the SDK package too).
