The program starts out on the graph screen and 2 accessory windows that show the spread contents.  The graph view screen has 3 areas of importance.  The Graph area shown by the green a, the spread bounds shown by the blue b, and and the toggle area shown by the red c.

    The graph area is where the portfolio spread data is displayed.  At the top left is the value displays of the value indicator planes.  When viewing the option spread model in 3D to find the values you simply have to move the value indicator planes which we’ll talk about later.  The graph itself is given by the strike price, days until opex and the spread value.  

   When the graph or logo first displays it is rotating.  Pressing the space bar toggles this action on and off.  This action works in windowed or fullscreen.

    Any scroll action will zoom the graph in and out, moving the mouse around will move the graph around accordingly.   Double clicking the graph area will toggle from zoom mode to the strike price value indicator plane.  Scrolling the mouse  wheel or track pad will move this indicator plane.  Double click again and now move the Day indicator with scroll.
