Overview

A lookback sets how far back pivots are found, and a setting extends earlier Fibonacci sets. Traders can show or hide individual ratios, level values, and a high-low diagonal line, or hide everything. An optional RSI mode calculates RSI from a chosen source and length and plots the oscillator with fixed bands. It is an indicator with no entry, exit, or stop rules.
