I've used this oscillator for years, even building systems around it. These days I use it when I'm looking for a fast filter. The most similar popular indicator is a very fast RSI. The indicator signals overbought as it passes above 0.7 and oversold as it passes below 0.3. Here we see it combined with. NinjaPriceAction. Members of the site can download this indicator in the files section of the site. I've made a NinjaTrader 8.0 version available there.
