Timeseries pricing on Datascope do not support " Market Capitalization" , hence historical data cannot be extracted.(eg. 1year)
However, you can calculate this value by extracting closing prices for a given period from timeseries/price history and multiply by Total Shares - Outstanding(from composite Template).
Thank you for answering! To clarify, does it mean it is possible to extract history of shares amount? I suppose the shares amount changes over time, so to calculate Market Cap for 1 year back from now, I'd need the closing price for that day and shares amount for that day, right?
