Reading this window

The projection called for Fast Stochastic %K to fall across the window, and it fell. The market travelled further than projected — the projection covered only 0.67 times the realised distance. Bar to bar, 62% of the moves ran the same way as the projection, and 30 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 9 (10:58 PM ET), where they sat 0.239899 apart, and furthest at bar 23 (11:13 PM ET) with a gap of 48.5069. The largest single-bar change in the recorded values came at bar 24 (11:14 PM ET), a move of -60.2448. 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.
