Reading this window

The projection called for Fast Stochastic %K to fall, while it rose instead. The projection overshot: it called for 1.49 times the distance the market actually travelled. Bar to bar, 64% of the moves ran the same way as the projection, and 20 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 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.
