Real-time data is covered by JET.Quotes:
JET.Quotes.create() .rics(".SPX") .formattedFields("CF_LAST") .onUpdate(onUpdate) .start();
What would be the equivalent request for fundamental and reference data, please?
E.g. in Eikon for Office terminology, something like TR.Revenue, or to take a parameterized example, TR.TotalReturn(sdate=0D,edate=-1AY).
