A simple indicator to make the cycle structure of markets more obvious.
The green bands and the blue bands indicate market sentiment. A new swing upwards in prices begins when the green band bottoms and begins to move up. A weakening of the market begins when the green band tops and begins top move down. The blue band mirrors the green band and provides balance to the chart so that relative volatility can be observed by judging the sizes of the areas enclosed by the green and blue bands.
