Abstract: The present invention provides an apparatus and method of determining and displaying trading trends for an investment underlying one or more options wherein an opening value and a closing value for the underlying investment for two or more time intervals is obtained. An opening value trend using a market trend indicator and the opening values for the investment is calculated, and a closing value trend using the market trend indicator and the closing values for the underlying investment is calculated. A visual indicator comparing the opening value trend to the closing value trend for the underlying investment is then displayed. This method may be incorporated into a computer program embodied in a computer readable medium using code segments to accomplish the method described above.
