🟦 USD.D = U.S. Dollar Dominance
It’s a relative strength chart that shows how the U.S. Dollar (USD) is performing compared to other asset classes, such as:
Stocks (e.g., SPX500)
Commodities (e.g., Gold, Oil)
Cryptocurrencies
Bonds
It's not a currency pair, but a dominance metric—similar in concept to BTC.D (Bitcoin Dominance) in crypto markets.
