The indicator code is a "literal" translation from MQL4 to MQL5.
In general, the indicator can be used for determining trend on high timeframes (day, week), and for receiving short-term alerts of volatility breakthrough on small timeframes (hour, 4 hours). Intraday traders and small TF fans may also like this indicator.
