I found something strange with the Dow Jones chart for Friday on Fidelity. When a chart is plotted by time, there should only be one point right? But this chart on Fidelity has 2 points for about an hour or so. Finding this amusing, I looked at Yahoo! finance chart for Dow Jones. There is something strange even there. The graph stopped at around 3pm EDT. Not sure what happened. Did the market close early on that day? Whatever the case may be, the chart on Fidelity looked funny.
