The indicator updates dynamically as new bars close, ensuring levels remain current. It integrates directly on the chart for straightforward visual reference. This tool supports various markets including Forex, cryptocurrencies, stocks, commodities, and indices, and is suitable for trading strategies such as scalping, breakout, and swing trading. By automating the plotting of significant price levels, it aids traders in aligning entries and managing setups with objective higher-timeframe anchors.
