Hi @Alex Putkov. I have not resolve this issue. Only worked around it. My workaround is not a solution but for temporary measure until I could spend a bit more time on this matter.

I could subscribe and rates with XAUMYR=R

Then I reconvert it back to USD/oz with MYR= rates.

Is not accurate but I'm still preplexed by the cause of getting XAU= rates via C# .API

@cewong Assuming you are using .NET Data API, I would suggest subscribing to OnStatusChange and OnError events to determine why do you not get XAU=:

private void Subscribe()
{
    var realtime = DataServices.Instance.Realtime;


    _subscription = realtime.SetupDataSubscription()
            .WithRics(“EUR=“, “GBP=“)
            .WithFields(“BID”, “ASK”)
            .OnDataUpdated(DataReceivedCallback)
            .OnStatusUpdated(StatusUpdatesCallback) 
            .OnError(ErrorCallback) //error call back
            .CreateAndStart();
}

Here is the list of statuses for your reference.

Ok. I'll try that. Will update progress after. Thank you.

@Zhenya Kovalyov - I made the addition as per your suggestion. The response I got for both SetupDataRequest & SetupDataSubscription was 'Ok'.

Code snippet looks like this,

@Alex Putkov. - Yes I get data update Quote App but not from the .NET API. This anomaly occurs only for XAU= and XAU=ALL. If I subscribe to currency such as EUR or AUD, there are data.

Note: Ignore the Elapsed Event heartbeat.

@cewong if you are using the standard example, please make sure that DataReceived looks at the correct keys in the update event:

private void DataReceivedCallback(IRealtimeUpdateDictionary updates)

        {

            if (updates.ContainsKey("XAU="))
            {
                if (updates["XAU="].ContainsKey("BID"))
                {
                    Console.WriteLine("XAU=(BID) {0}", updates["XAU="]["BID"].Value.ToString());
                    subscription.Stop();
                    Program.StopMessagePump();

                }

            }

        }

Might that be the case?

@Zhenya Kovalyov yes, in fact, my code just display any keys subscribed. As long as there is an event from EIkon's service, I should be able to show. Unfortunately, that wasn't the case.

@cewong
Were you able to resolve the issue? I'm afraid I'm out of suggestions. The fact that the issue is only happening for a couple of RICs and that you can view these RICs in a Quote app in Eikon makes no sense to me. If indeed you found the root cause of the problem, I'd very much appreciate you sharing it on this thread.

Hi @Alex Putkov. & @Zhenya Kovalyov

An update. I noticed for RIC XAU= is from Commodity but XAUSGD=R is from FX.

1) Is there a difference in subscribing via .NET API for commodity versus Foreign Exchange (FX)?

2) How do I check if my subscription has access via API to Commodity RIC?

Thanks.
