SUNE stands for SUN EDISON which was an excellent company from 2005 (or perhaps earlier) judged by its Balance Sheet and P&L data up until and including H1 of 2009, after that excellence tapered off considerably. In order to effectively do backtesting this ticker symbol should be included in my research. SUNE has been delisted since 2017-05-28. Question: Which RIC do I use to retrieve historic data for SUNE? If there is one how could I have found it myself?
