This is a momentum, trend, as well as a divergence indicator.
It is similar to CCI, though it is based on a slow and fast EMA in connection to ATR, which
allows to interprete it easily.
Both EMAs and ATR have customisable period.
Further explanation and basic usage can be found in the comment section inside the script.

No tuning required anymore apart the usual lookback periods.
