DXY (Dollar Index) represents the strength of the dollar against major currency pairs. But it is more than that. Nearly all financial markets are so far dependent on the usdollar directly or indirectly. That means if dollar moves up and down nearly all markets including indices (us500, dow jones etc.) , cryptos (Bitcoin, ethereum etc.), commodities (gold, silver, usoil etc.) will move up and down.
