What is Schaff Trend Cycle?

The Schaff Trend Cycle, from Doug Schaff, runs MACD through a double stochastic process. The result is a bounded 0 to 100 oscillator that aims to identify trends faster than MACD.

Schaff Trend Cycle formula

Output	Calculation
Base	EMA(fastLength) − EMA(slowLength)
STC	Double-smoothed stochastic of the base over cycleLength
