Reading this window

The projection called for Fast Stochastic %K to rise across the window, and it rose. The market travelled further than projected — the projection covered only 0.51 times the realised distance. Bar to bar, 64% of the moves ran the same way as the projection, and 22 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.

How the window developed

The two paths were closest at bar 4 (12:28 AM ET), where they sat 1.13781 apart, and furthest at bar 28 (12:53 AM ET) with a gap of 48.0124. The largest single-bar change in the recorded values came at bar 27 (12:52 AM ET), a move of +39.9244. The projected and recorded paths crossed at least once inside the window.

About Fast Stochastic %K on a 1-minute chart

The fast Stochastic applies less smoothing than the standard version, so it turns sooner and moves more sharply. 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.
