About

Stochastic Oscillator plots where the close sits within the recent high-low range. %K is the raw oscillator; %D is the smoothed version.

Above 80 = overbought, below 20 = oversold.
%K crossing above %D in the oversold zone is the textbook buy.
Raise Length to filter noise, lower it for faster reversals.
