Thomson Reuters Eikon Excel: Eikon Excel refresh rate depends on Excel. Excel evaluates formulas by default once a second. A setting named RTD Throttle Interval controls this frequency. You can configure this setting in the Eikon Excel option dialog box Thomson Reuters, Options, Settings, RTD Refresh Rate).

The refresh rate can also be modified when using volatile formulas, VBA code and other advanced Excel techniques.

With VBA, the refresh rate can be read and set using Application.RTD.ThrottleInterval.

Sub SetThrottleRate()
    MsgBox Application.RTD.ThrottleInterval
   
    Application.RTD.ThrottleInterval = 30000 ' Interval in milliseconds.
End Sub

This value will be carried from Excel session to Excel session until changed.

HOWEVER - if the Eikon for Excel value is different then this will change/overwrite the value in the example above. The Eikon for Excel real time update value is set from the Thomson Reuters ribbon, Options, Settings, Data Retrieval and then the RTD throttle interval.
