The MESA Adaptive Moving Average (MAMA) adapts to price movement in an entirely new and unique way. The adapation is based on the rate change of phase as measured by the Hilbert Transform Discriminator I have previously described. The advantage of this method of adaptation is that it features a fast attack average and a slow decay average so that composite average rapidly ratchets behind price changes and holds the average value until the next ratchet occurs.
An interesting set of indicators result if the MAMA is applied to the first MAMA line to produce a Following Adaptive Moving Average (FAMA). By using an alpha in FAMA that is half the value of the alpha in MAMA, the FAMA has steps in time synchronization with MAMA, but the vertical movement is not as great. As a result, MAMA and FAMA do not cross unless there has been a major change in market direction. This suggests an adaptive moving average crossover system that is virtually free of whipsaw trades.

nice work , nicolas , very good.
Hi.
When I import MAMA the blue and red lines appear twice on my chart. Any way of getting only one line of each to appear?
thanks
You have certainly apply the indicator twice on the price chart. If you want to hide one of the curve, you can set its Style to “invisible”.
Buongiorno Nicolas,
come faccio a trasformare questo interessantissimo indicatore in uno screener long/short?
Grazie,
Fabrizio

A great job Nicolas, thanks. A question about averages, what period is the fast average and what period is the slow average? thank you
This Indicator is very useful if the Risk number is altered to suit the time frame, volume or tick count. If combined with the PRC ASC Trend, also adjusted to suit, then some good results can be had. Thank you
how are you applying it to asc trend
error displaying, code must end with RETURN. Any idea hot to fix it?
