All Implemented Interfaces:

ChartRenderer

public final class ParabolicSARRenderer
extends BaseRenderer

ParabolicSARRenderer - Parabolic Stop and Reverse

Professional Parabolic SAR renderer for stop-loss and trend reversal points. Displays dots above (downtrend) or below (uptrend) price bars.

This implementation is optimized for Swing painting: all indicator series are cached in primitive arrays and reused. No per-point allocations occur inside drawData(Graphics2D, ChartModel, PlotContext).
