Even for today, they now have 9978.74, now it's got me wondering if this is a bottom based on the miss of data at the top (Dow 11,000+) and now the miss of data for today (Dow -10,000)... weird stuff my friend... weird stuff...
stockcharts.com is clearly the best charting service... CLEARLY... and most accurate too...
That is odd. If you pull up a close inspection of the chart 1 month of candles or less it seems to show the correct high.
I'm not sure where they are getting their data for those chart but it looks like this will be the last time I use them for any more charts. That kind of information is critical. Especially a 52 week high.
