A multi-reversal line touches the bottoms as well as the tops of the price bars. Multi-reversal lines are mostly used as a reference for action/reaction lines but also for future support or resistance in relation with future price projections (See Slide 19):
In Slide 19, look at how multi-reversal lines show support and resistance to future price movement. Multi-reversal lines complement ['kɔmplɪmənt] (доповнює) price targets, since they can be used as reference for future price support and resistance.
Note how all multi-reversal lines are close to the $25 target given by a Fibonacci projection (horizontal line).
The centerline and multi-reversal line are most useful finding targets both price and time related.
