DXY Custom + is a customizable synthetic USD index plugin designed for advanced foreign exchange (FX) analysis. It extends the traditional US Dollar Index (DXY) by including AUDUSD and NZDUSD currency pairs, creating a broader FX-sensitive USD benchmark. Users can fully customize the weights of all basket components to tailor the index to specific trading styles, macroeconomic conditions, and liquidity environments.

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

Key technical features include a persistent synthetic candle cache, improved chart refresh stability, secure local file operations, EMA-based normalized activity volume modeling, forward-fill quality filtering, spread validation, and stale quote protection. The plugin maintains a cross-broker compatible architecture and persistent runtime state for enhanced reload stability.

DXY Custom + focuses exclusively on FX markets, excluding external assets like gold or indices. It is suitable for broad FX-based USD analysis, commodity-currency sentiment monitoring, synthetic DXY-style charting, and strategy-specific index construction. The plugin relies on the quality of the broker’s market data and may require a short initialization period on first use or after parameter changes.
