Overview

ezTrend Lines identifies pivot highs and pivot lows on the chosen oscillator line using configurable pivot periods and checks up to three pivot points. By identifying these high and low swing points, the script draws trend lines directly across the oscillator values. Users can adjust oscillator lengths, MACD parameters, and pivot point periods to customize trend line sensitivity.

Multi-oscillator support for RSI, CCI, Momentum, OBV, and MACD
Automatic pivot high and pivot low detection on indicator lines
Configurable pivot point periods and historical pivot depth
Customizable MACD parameters and oscillator horizontal levels

Third-party code. ForexR did not write, test or endorse this script, and the summary above was generated automatically from its code and README. Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
