How to get real time data for a few currencies with AdxRtList simultaneously?

aidynchik_84

Hello! I am writing application on C#. To get real time data for one currency I writing this:

AdxRtList.Source = "IDN";
            AdxRtList.RegisterItems("GPB=", "BID");
            AdxRtList.StartUpdates(RT_RunMode.RT_MODE_ONUPDATE);

and this

void adxRtList_OnUpdate(string a_itemName, object a_userTag, RT_ItemStatus a_itemStatus)
        {
            //use item name to get the data
            object temp = AdxRtList.get_ListFields(a_itemName, RT_FieldRowView.RT_FRV_ALL, RT_FieldColumnView.RT_FCV_VALUE);
            object[,] l_fields = (object[,])Convert.ChangeType(temp, typeof(object[,]));
            label5.Text = a_itemName + ": " + l_fields[0, 1];


            AdxRtList.StopUpdates();
        }

But I need to get data for 30 currencies, how can I do it? I tried to write

AdxRtList.RegisterItems("GPB=, AUD=, RUB=", "BID");

but it doesn't work.

I found solution - simple array

Hi @aidynchik_84, you are correct! We would support a variant or a param array both for the list of instruments or the list of fields.

Hi @zhenyakovalyov

Tell me please when I can stop AdxRtList updates? I need to launch AdxRtList only once, and then I need to stop it. But I can't do that on adxRtList_OnUpdate, because I don't know how many currencies did I get

This will do:

mRtList.StopUpdates

You can also consider using rtList in the snapshot mode. When requesting the updates, select this:

With mRtList
        .Source = "IDN"
        .RegisterItems instrumentList, fields
        .StartUpdates RT_MODE_IMAGE
End With

As a result, rt list will not subscribe to the updates but only get a snapshot of values. Make sure that you use an appropriate event handler for this:

Private Sub mRtList_OnImage(ByVal a_dataStatus As AdfinXRtLib.RT_DataStatus)

End Sub

I wrote as you said

AdxRtList.StartUpdates(RT_RunMode.RT_MODE_IMAGE);
....
void adxRtList_OnImage(RT_DataStatus a_itemStatus)
        {
            //use item name to get the data
            string a_itemName = "";
            object temp = AdxRtList.get_ListFields(a_itemName, RT_FieldRowView.RT_FRV_ALL, RT_FieldColumnView.RT_FCV_VALUE);

now I'm getting an error {"ERROR #360f - AdxRtList : invalid item "} on

object temp = AdxRtList.get_ListFields(a_itemName, RT_FieldRowView.RT_FRV_ALL, RT_FieldColumnView.RT_FCV_VALUE);

according to your code, a_itemName is an empty string, it should be a RIC, for instance:

object temp = AdxRtList.get_ListFields("RUB=", RT_FieldRowView.RT_FRV_ALL, RT_FieldColumnView.RT_FCV_VALUE);
