A Swing High is a "peak" identified within a series of bars or within an indicator or oscillator. A Swing High consists of two "legs", and starts with an initial up leg which is then followed by a down leg. A leg is defined as two or more bars going in any one direction. For example, when two or more consecutive bars produce higher (bar) highs and higher (bar) lows. In this instance, the smallest possible up leg would have developed. Inversely, to have a down leg you need no fewer than two bars showing lower (bar) highs and lower (bar) lows. When an up leg is followed by a down leg, the "peak" that is created is considered a Swing High.
