Hello Jaspersoft Community, I am a new user of Jaspersoft and I am trying to create variables that can help me analyze financial data. For example, how can I go about recreating the Sharpe ratio calculation given a set of historical data and a daily PL (or cumulative) of a set of trades? (RORPortfolio - RORRisk Free) / STDPortfolio. If I am unable to do this, I can imagine a function doing this separately and passing it in, but how/where would I enact this function? I am trying to find detailed documentation for how to use Jaspersoft but I have been unable to find what I am looking for. Help would be greatly appreciated. Thank you in advance!
