New PRO user here (installed MarketXLS 11/5/2017) Last(Symbol) and Open(Symbol) functions have three variants. No documentation. What is the difference between LAST, LAST1 and LAST2? Same for OPEN. P.S. Documentation on the MarketXLS functions (e.g. calculation basis) and proper function error indication is sorely needed. For function errors, on hf Functions using the quarter, TTM options, if the data does not exist or the server is down. Possibly use the same error reporting as in cars (a published lookup code). Excel based error statements provide very limited clarity on resolving a errors. I have had to query my other sources of company financial data to verify if financial data is available and the data accuracy. The overhead in using MarketXLS is piling up. Hope it gets better. Thank you.
