Overview

My Fractals evaluates high and low price relationships across surrounding bars according to a configurable period setting. Reversal points are visually highlighted with arrow character markers placed above and below candle bars. Because fractal detection requires confirming future bars, signals are plotted with a negative offset and appear retroactively.
