High/Low Bands   

High/Low Bands consist of triangular moving averages calculated from the underling price, shifted up and down by a fixed percentage and include a median value.

When prices rise above the upper band or fall below the lower band, a change in direction may occur when the price penetrates the band after a small reversal from the opposite direction.

It is used to relative price levels and volatility. It can be combined with price action and other indicators to generate signals and foreshadow significant moves.
