Q: Seeing the whole financial chart I display a financial chart which I display with InteractiveTradingChart[]. My problem is that when my financial is displayed, even though I ask for 6 months of data, the chart only shows a subset of that. I can go to the bottom of the chart and enlarge the area of interest manually. How do I tell InteractiveTradingChart[] to display the whole time period I requested?

A: Edit
My initial answer seems to have missed the point, which was about how to call up InteractiveTradingChart[] with its controls initialized to some values other than defaults.
Someone more able than moi may want to examine the output from 
InteractiveTradingChart[{"GOOG", {{2009, 1, 1}, {2009, 12, 31}}}]
FullGraphics[%] // InputForm

and determine whether variables such as plotrangemin can be set by the programmer.

The date range you specify in the command sets the full time period you work with. The actual display is handled by the buttons and slider at the button of the chart.  If you click on the Max setter button, the whole period will be displayed.  If you click on the month button, one month will be displayed.  You may move to other months (than the one currently being displayed) by using the Slider.  Same respective behavior for Week.
By default, the chart does not display the full time period but rather only a part of it.
