I'm receiving financial data from Bloomberg and would love to convert the data received to a FinancialData object that can be consumed by InteractiveTradingChart, etc. Any tips to accomplish this would be helpful.

Hi Luke,

TradingChart and InteractiveTradingChart expect OHLCV data as TemporalData or TimeSeries. e.g.

ge = FinancialData["GE", "OHLCV", {"Oct. 29, 2020", "Nov. 1, 2020"}];
Head@ge
(* TemporalData *)

geList = Normal@ge
(*
{{DateObject[{2020, 10, 29, 0, 0, 0.}, "Instant", "Gregorian", -6.], 
 {Quantity[7.659999847412109, "USDollars"], 
   Quantity[7.739999771118164, "USDollars"], 
   Quantity[7.309999942779541, "USDollars"], 
   Quantity[7.369999885559082, "USDollars"],
   122645696}}, 
 {DateObject[{2020, 10, 30, 0, 0, 0.}, "Instant",  "Gregorian", -6.], 
  {Quantity[7.340000152587891, "USDollars"], 
   Quantity[7.539999961853027, "USDollars"], 
   Quantity[7.289999961853027, "USDollars"], 
   Quantity[7.420000076293945, "USDollars"],
   102480596}}}
*)

Convert from List to TimeSeries

geTS = TimeSeries@geList

TradingChart@geTS

Convert the Bloomberg data into a list like geList then generate a TimeSeries from it.

I was able to get this into the interactive trading chart by formatting the data at each iteration for the time series in the parameterized format of InteractiveTradingChart.

You don't need to go from a TimeSeries object to a TradingChart[ Normal[ TimeSeries[..] ]] since both TradingChart and InteractiveTradingChartChart accept TimeSeries objects with values of dimension 5, ie OHLCV. Eg

In[108]:= FinancialData["GE","OHLCV",{"Oct. 29, 2019","Nov. 1, 2020"}]
Out[108]= TimeSeries[Time: 29 Oct 2019 to 30 Oct 2020 Data points: 255  \[SpanFromLeft]]
In[109]:= InteractiveTradingChart[%]
