DXY Classic Symbol is a synthetic USD index plugin designed for use within cTrader. It replicates the traditional U.S. Dollar Index (DXY) by employing the original six currency components—EUR (57.6%), JPY (13.6%), GBP (11.9%), CAD (9.1%), SEK (4.2%), and CHF (3.6%)—with fixed institutional-style weights. This deterministic, non-customizable structure provides a clean and familiar benchmark for analyzing U.S. Dollar strength.

The symbol operates as a standard chart under the Custom Symbols section, supporting all typical charting features such as indicators, templates, drawing tools, and workflows. It includes a low-latency synthetic pricing engine, stable historical candle reconstruction, and synthetic tick volume generation compatible with volume-based indicators like VWAP and Volume Profile.

Technical features include a persistent synthetic candle cache, improved chart refresh stability, forward-fill quality filtering, spread validation, and stale quote protection. The plugin is cross-broker compatible and maintains persistent runtime state to enhance reload stability.

Use cases focus on traditional DXY-style charting, macro-driven USD analysis, institutional USD benchmark tracking, and technical analysis workflows. The symbol depends on the broker’s underlying market data quality and may require a brief initialization period on first launch.
