The Historical US Dollar Index HMA Indicator is a cTrader tool designed to provide a dynamic measure of the U.S. Dollar's strength. It calculates a custom US Dollar Index by aggregating weighted percentage changes from six major currency pairs: EURUSD, USDJPY, GBPUSD, USDCAD, USDCHF, and USDSEK. Users can adjust the weights to tailor the index according to their market insights.

Key functionalities include the use of dual Hull Moving Averages (short- and long-period) to capture both immediate trends and long-term momentum, and smoothed slope analysis of the long-period Hull MA to identify potential market reversals early. The indicator integrates real-time market data from multiple sources to ensure accurate and current analysis. Parameters such as lookback periods and moving average lengths are customizable, allowing alignment with individual trading styles and strategies.

This indicator supports forex markets through its focus on major USD currency pairs and provides comprehensive trend analysis to assist traders in making informed decisions based on the U.S. Dollar's market behavior.
