Fix the chart view's "1D" date range option OR add a new "today" date range option
Right now when one clicks the [1D] button it will set the graph range to a full day's range, but not to "today's" date range. If one were to want to see how a stock is tracking over the course of today, one would have to drag the graph to a very specific range to have the current stock match the symbol's performance.
To give an example, lets say I'm viewing the YAHOO stock on a chart at noon, and right now the stock is up 0.5% for the day, if I press 1D it will orient the graph to display between yesterday at noon and today at noon and the YAHOO stocks graph will not be ending at 0.5% because it is skewed from yesterday's data.
In summary there should be an option to orient the graph between today's open and today's close.
