I would like to request API functionality to download historical (e.g. daily) equity (portfolio value) data available at the web dashboard so that I can calculate risk-adjusted metrics. It could also be good to embed functions within Quantopian Empyrical into the API in my opinion to analyze stuff like Max. Drawdown, Sortino Ratio, Sharpe Ratio, etc and also demonstrate those metrics at a dashboard in the Web interface along with the balance.
Note: I see that somebody else also requested this in Portfolio History Endpoint
