An enhancement of the Carbon WAM Market Cycle indicator that includes an additional Carbon WAM with a different period on the same plot. The goal is to highlight the relationship between volatility and market cycles over two different periods - 3 and 21 seem to be a good combination.
The short period WAM provides an early warning for a trend change, and the long period WAM stays in bullish or bearish mode for most of the trend.
A possible system to use with this indicator is look for crossovers between the short period and long period WAMs and zero crossings on the individual WAMs.
