The Round Numbers indicator automatically plots horizontal support and resistance lines at psychologically significant round number price levels on trading charts. It identifies three types of levels based on customizable pip intervals: major levels (solid red lines, typically every 100 pips), minor levels (dotted blue lines, typically every 50 pips), and trace levels (sparse white dots, typically every 25 pips). These levels represent price points where traders often place orders, influencing market behavior.

Key features include full customization of pip intervals, colors, and line styles for each level type, ensuring clear chart visibility. The indicator updates dynamically as prices move to maintain relevant support and resistance lines. It is designed to provide a clean, professional appearance without cluttering charts and is compatible with all timeframes and currency pairs. Users can disable any level type by setting its interval to zero.

This tool supports multiple markets including Forex, indices, commodities, cryptocurrencies, and stocks, making it versatile for various trading strategies that rely on psychological price barriers.
