I think it may be a formatting issue or something. I found an old thread with a similar complaint, but the solution offered doesn't help me. When i refer to a cell for the "start" and "end" dates using the "GetIntervals" method, and those cells have the dates i want in them and are in some excel date format, it seems to just ignore the date requests, and give me results in the requested interval counting backwards from now. When i spell out the dates in YYYY-MM-DD format in quotes within the function itself, it returns "no data retrieved" i have attached the file for your reference. As a further question, a few days ago during a live demo you showed me a way to call historical OHLCV data between two specific time, but the "GetIntervals" method only takes start and end dates, not start and end times. can you tell me what you used to do that. i believe the syntax involved the "^" symbol. I've also noticed a similar issue with the "Custom Dates" option in the MarketXLS tab. when choosing to get data on a minutely basis, it responds 'NoneType' object has no attribute '__getitem__' or "no data" or something like that.
