This indicator a classic EMA with a smoothed Stochastic oscillating around it, using the EMA as midpoint of the Stochastic oscilator. It can be used as an overlay on your chart using the EMA as support and resistance or as an independent indicator under your chart. You have to trim the width of the Stochastic depending on the value of your asset, so USD/JPY=1 and EUR/USD=300. This is a great trend following and momentum indicator.
