ADX - The Anti-Dollar Index - is an index based on four major safe-haven assets stronger than dollar such as Gold, British Pound, Japanese Yen and Swiss Franc. The combination of these assets measures the force of the dollar against the other popular markets assets and indexes.
The idea behind the creation of this index is to measure with accuracy the force of the dollar and the if the market is in a risk-on or risk-off trend, due the fact that DXY is an outdated dollar index which has the euro as a main component and then delivers a biased and inaccurate balance of dollar strength in the market.
