Alternatively, when the MAMA crosses below the FAMA a sell signal is given.The MESA Adaptive Moving Average is a technical trend-following indicator which adapts to price movement “based on the rate change of phase as measured by the Hilbert Transform Discriminator”. This method of adaptation features a fast and a slow moving average so that the composite moving average swiftly responds to price changes and holds the average value until the next bar’s close. The Averages act as support and resistance areas and the price will tend to react to them. This makes pullbacks to the MAMA and FAMA suitable with-trend entry areas.  As with most technical indicators, the MAMA is best used in conjuction with additional signals.

RSI can be used to help spot overbought or oversold conditions. An RSI reading over 70 would be considered overbought, and a reading under 30 would indicate oversold conditions. A level of 50 would indicate neutral market momentum. The 14-day RSI is currently sitting at 70.58, the 7-day is at 81.57, and the 3-day is spotted at 91.26.
