I solved my own problem...
Im using MT4 and I see that the DXY is this:
USDX = 50.14348112 × EUR/USD^(-0.576) × USD/JPY^(0.136) × GBP/USD^(-0.119) × USD/CAD^(0.091) × USD/SEK^(0.042) × USD/CHF^(0.036)
luckily there is already a script for this...
If anyone knows of the same index live on some website it might help someone in future...
