The On Balance Volume USD - Combined indicator consolidates on-balance volume data from six major USD currency pairs—EUR/USD, GBP/USD, AUD/USD, USD/JPY, USD/CHF, and USD/CAD—into a single line. This composite signal reflects the real buying and selling activity of the U.S. dollar across these pairs, providing a clear momentum gauge without the need to monitor multiple charts. The indicator automatically adjusts its readings so that upward movements represent dollar demand and downward movements indicate dollar supply. Users can also customize the indicator by swapping in any USD pair to create a tailored momentum measure. It is designed to help traders identify when large market participants are accumulating or distributing dollars and to detect early signs of breakouts or reversals. Suitable for both short-term news-driven trading and longer-term swing strategies, this tool aims to keep traders focused on true dollar strength in the foreign exchange market.
