Swami Stochastics

Swami Stochastics was developed by John Ehlers and Ric Way. It utilizes a series of stochastic values to determine bullish and bearish periods. The indicator will be green when entering a bullish period, red when entering a bearish period. Yellow is displayed when the direction is indeterminate. The user may change the period lengths. This indicator’s definition is further expressed in the raw code given in the calculation below.
