Reading this window

Bar to bar, 69% of the moves ran the same way as the projection, and 19 of the 30 bars finished on the projected side of the opening reading. One window is a single observation, not a pattern; it is published here so the projection and the outcome can be checked against each other.

About Average True Range on a 15-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 15-minute timeframe a 30-bar projection covers 7.5 hours of trading, so the window above describes 7.5 hours of Micro E-mini Nasdaq 100 activity rather than a single print.
