drawShapeRelative( barIndex, yValue, shape, url, color, Flags [, tagID] )
The drawShapeRelative function allows you to draw shape objects at any location on your chart. Any shape object created with drawShapeRelative will 'stick' to the location where it was originally anchored. So, a shape object originally created at a bar index of -10 will be at a bar index of -20 after 10 new bars come in.
