Reading this window

The projection called for Fast Stochastic %K to fall across the window, and it fell. The projection overshot: it called for 1.69 times the distance the market actually travelled. Bar to bar, 69% of the moves ran the same way as the projection, and 23 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 20 (5:46 PM ET), where they sat 2.02424 apart, and furthest at bar 0 (5:27 PM ET) with a gap of 73.3032.

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.
