MDS / DXY
DXY - US Dollar Index
What it measures
The dollar's value against a basket of six currencies. The euro's large weight makes DXY sensitive to EURUSD. It is not an average of all world currencies.
Why traders follow it
Compare DXY with gold over the same time window. A rising DXY often weighs on gold, but the relationship changes. DXY alone does not confirm an XAUUSD trade.
Check the country, period and source. A single value or regime label does not determine a trade's direction.
