SupportResistance is an indicator designed to automatically detect and plot major support and resistance levels on trading charts using swing-based logic. It operates exclusively on the H4 (4-hour) timeframe to identify these key levels, while allowing application on any chart timeframe with the support and resistance levels remaining fixed to H4. The indicator is currently limited to the XAUUSD symbol (gold vs. US dollar) for controlled trial access. Features include highlighting pullbacks and break of structure (BOS) retests, filtering signals with candle confirmation, and improved level clustering through pip-based flattening to reduce duplicate or overlapping lines. It also incorporates a robust object-cleanup system to ensure smooth redrawing and stable performance. An on-chart notice provides information about limitations and upgrade instructions. This tool is intended to assist traders in identifying critical price levels and market structure on the XAUUSD market.
