Does gold always fall when the dollar rises?

No. The inverse relationship is a tendency, and it breaks down during risk shocks when both the dollar and gold are bought as havens.

What currencies are in the DXY?

Six: the euro, Japanese yen, British pound, Canadian dollar, Swedish krona and Swiss franc, with the euro carrying by far the largest weight.

Is DXY or real yields more important for gold?

Real yields tend to dominate over longer horizons. Which matters more in a given week should be measured, not assumed.

Can I trade gold off the DXY chart alone?

No. It is context for direction and conviction, not an entry signal, and correlation strength varies substantially over time.

WHAT IS THE DXY?

The DXY is the US dollar index, a weighted measure of the dollar against six major currencies dominated by the euro. Because gold is quoted in dollars, dollar strength raises the effective cost of an ounce for non-dollar buyers and softens marginal demand, which is the mechanical basis for the familiar inverse relationship between the DXY and XAUUSD.

The relationship is a tendency rather than a rule. In a genuine risk shock both the dollar and gold can be bid simultaneously as havens, and over longer horizons real yields often dominate dollar moves as the primary driver. The DXY is therefore best used as macro context that raises or lowers conviction on a gold setup, not as a standalone entry signal.
