Heiken Ashi is good for cleaning up noise but I don't want it to obscure real price action like all the ones I have come across do.
This very simple indicator just puts Heiken Ashi candles off the main chart so you can see the real price action and the Heiken Ashi version of price action at the same time. I find the dual view far more useful than completely replacing real price action with Heiken Ashi smoothing.
