Reading this window

Bar to bar, 62% 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.

About Fast Stochastic %K on a 59-minute chart

The fast Stochastic applies less smoothing than the standard version, so it turns sooner and moves more sharply. On the 59-minute timeframe a 30-bar projection covers 29.5 hours of trading, so the window above describes 29.5 hours of Micro E-mini Nasdaq 100 activity rather than a single print.
