Symmetry Explained
Symmetry is simple, compelling and widely overlooked. You simply measure the height of recent moves (upward or downward) and compare them to any current price moves in development. You can make projections on the potential height or depth of the current move. Positions could be taken based, in part, on how the current move compares symmetrically to prior moves. Also, if the symmetry is broken the potential for a lower high or higher low has increased implying trend reversal.
Examples of symmetry can be found in the charts section of this site here and here.
