Bar to bar, 62% of the moves ran the same way as the projection, and 27 of the 30 bars finished on the projected side of the opening reading.

About Average True Range on a 1-minute chart

Average True Range measures how much ground a market covers per bar. It describes volatility, not direction, so a rising ATR means wider bars rather than higher prices. On the 1-minute timeframe a 30-bar projection covers 30 minutes of trading, so the window above describes 30 minutes of Micro E-mini Nasdaq 100 activity rather than a single print.
