The widest ATR stop over the recent window, upper and lower.
First an ATR stop per candle, then the most extreme of those over the same window. That makes the line quieter than a plain ATR stop.
Worked out by the same code the builder uses, on stored daily candles. Move a setting and the line moves with it. This is what happened, not what will happen.
Exit: Price close crosses below Chande Kroll stop lower.
Quieter also means further away: it gives back more of an open profit before it triggers.
