I think the problem is going deeper than that. It looks like they have no historical prices for anything on the 15th at the moment. Check out this chart: https://finance.yahoo.com/chart/FB#eyJtdWx0aUNvbG9yTGluZSI6ZmFsc2UsImJvbGxpbmdlclVwcGVyQ29sb3IiOiIjZTIwMDgxIiwiYm9sbGluZ2VyTG93ZXJDb2xvciI6IiM5NTUyZmYiLCJtZmlMaW5lQ29sb3IiOiIjNDVlM2ZmIiwibWFjZERpdmVyZ2VuY2VDb2xvciI6IiNmZjdiMTIiLCJtYWNkTWFjZENvbG9yIjoiIzc4N2Q4MiIsIm1hY2RTaWduYWxDb2xvciI6IiMwMDAwMDAiLCJyc2lMaW5lQ29sb3IiOiIjZmZiNzAwIiwic3RvY2hLTGluZUNvbG9yIjoiI2ZmYjcwMCIsInN0b2NoRExpbmVDb2xvciI6IiM0NWUzZmYiLCJyYW5nZSI6IjFtbyIsImFsbG93Q2hhcnRTdGFja2luZyI6dHJ1ZX0%3D If you set the time interval for 5 days, the chart will show data for the 15th, presumedly that's their realtime data. If you change the interval to 1 month, the chart goes straight from the 12th to the 16th, it completely bypasses the 15th. I think there's realtime data, but no historical data. I have been using their services for a couple years and never seen anything like this. I think it's a bug in their system, but it's hard to say what's going on exactly.
