ChartOverlay provides you with a transparent (or translucent) window through which you can view a chart displayed by another program and upon which you can draw various studies that interest you.

Because neither the overlay nor the underlying chart program is aware of the other, you can use ChartOverlay anywhere. You can use ChartOverlay with end-of-day or real-time charting programs, web browsers, spreadsheets, PDF files, newsletters and the like.
