Just all vanished. But I could try what you suggest, go back to the real ticker, leave it again for the new fake one and choose to delete the real ticker's price history and then come back again and see if it will accept new price info at that point. Gotta go deal with a plumber right now, but I'll give that a try later. Thanks for the suggestion.
