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
Trend Strength Index plots two lines in a separate pane: a fast smoothed Trend Strength Index line based on the user-defined smoothing length, and a slower 100-period simple moving average baseline. Users can adjust the calculation lookback length and the fast smoothing period to tune responsiveness across different market speeds. The script acts purely as an analytical oscillator without built-in trade signals or alerts.
- Efficiency-based trend strength calculation
- Adjustable lookback length and smoothing period
- Fast simple moving average plot
- 100-period moving average baseline
- Separate pane oscillator display
