This indicator plots the Schaff Trend Cycle in a separate pane. It subtracts a slow exponential moving average from a fast one, applies a stochastic cycle twice, and smooths each result to form a 0–100 oscillator. Line color follows the slope, or the upper and

Overview
The moving average type can be SMA, EMA or WMA, momentum can be smoothed, and three color themes are available. The increment, smoothing, number of rows plotted and the normalization lookback are adjustable. Bars can optionally be painted, and a waves option changes the row spacing.
- Heat map of up to 28 momentum rows
- SMA, EMA or WMA selection
- Three color themes
- Adjustable normalization lookback
- Optional bar painting
