Reading this window

The projection called for Average True Range to fall across the window, and it fell. The projection overshot: it called for 1.90 times the distance the market actually travelled. Bar to bar, 62% of the moves ran the same way as the projection, and 26 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.

The two paths were closest at bar 16 (1:37 AM ET), where they sat 0.180831 apart, and furthest at bar 0 (1:22 AM ET) with a gap of 9.66004.

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 BTCUSD activity rather than a single print.
