DXY Custom Symbol is a customizable synthetic USD index plugin that enables users to construct a flexible USD basket based on the traditional six-component DXY structure. It allows direct adjustment of individual currency weights through input parameters, supporting personalized market analysis and strategy-specific index construction. The symbol functions like a standard chart within the Custom Symbols section, compatible with indicators, templates, drawing tools, and chart workflows.

Key technical features include a low-latency synthetic pricing engine, persistent synthetic candle caching, stable historical candle reconstruction, and built-in synthetic tick volume generation. The model supports volume-based indicators such as VWAP and Volume Profile, along with standard technical analysis tools. It handles both direct and inverted currency components and maintains cross-broker compatibility with persistent runtime state for improved reload stability.

This plugin is designed for custom USD basket analysis, synthetic DXY-style charting, macro-driven USD evaluation, and volume-based technical workflows. It focuses solely on the classic DXY currency basket without extended components like AUD, NZD, or gold, ensuring a lightweight yet fully customizable framework. The symbol’s accuracy depends on the quality of the broker’s underlying market data and may require an initialization period for synthetic history and cache preparation.
