(FRAMA) Fractal Adaptive Moving Average

This script plots UP TO 4 FRAMAs (Fractal Adaptive Moving Average), a particularly useful adaptive MA which uses fractal price theory to "adapt" itself, or better, to auto-adjust its parameters. It's quite reactive, but its major strength resides in its ability to filter the noise during lateral price movements, avoiding some false signal provided by more common moving averages.

By default, the script plots the basic FRAMA version, the one firstly developed by John Ehlers, but also provides the possibility to play with the parameters, to obtain a modified FRAMA.
Unfortunately I'm not able to provide web sources about FRAMA here, due to Tradingview policies. So search online if you need more details about FRAMAs.

Please show me your support if you like my scripts. Hope you enjoy them.
