ATR Normalized Relative Strength

ATR Normalized Relative Strength measures how strongly the current chart symbol is moving relative to a chosen comparison symbol after adjusting both for their own volatility. It divides each symbol’s price by its 14-period ATR, then plots the ratio of those two normalized values. Readings above 1 indicate the chart symbol is outperforming the comparison symbol on an ATR-normalized basis, while readings below 1 indicate underperformance.
