drawShapeAbsolute( barIndex, yValue, shape, url, color, Flags [, tagID] )
The drawShapeAbsolute function allows you to draw shape objects at any location on your chart. Any shape object created with drawShapeAbsolute will remain at its designated relative offset from the most current bar. So, a shape object drawn with drawShapeAbsolute at a bar index of -10 will always remain 10 bars back from the most current bar.
