Hello Sir!
This AFL, that you are talkikg about, is in 'Indicators' folder in Ami, named 'Volatility (Wilder)'.

The code is simple, and it is based on ATR.

_SECTION_BEGIN("Volatility");
Plot( ATR( Param("Periods", 14, 1, 100 ) ), _DEFAULT_NAME(), ParamColor("Color", ColorCycle ) );
_SECTION_END();
