Duh, well, there is that. I got so wrapped around the axle on the unnecessary shortening that I completely missed the symbol typo on a stock I've traded probably at least monthly (and probably view daily) for the last fifteen years.
Poor Appell Petroleum Corp (APPL) went out of business in 2016, probably because nobody could find their stock symbol to invest, since every search engine autocorrects it to AAPL...
