There is something broken when shorter term interest rates go higher while the currency falls, and when it is the worlds largest economy it kinda matters. It means the US paper debt is not that attractive due to elevated inflation risks. 

It looks like 2018 is repeating 1985-1988 gold trend, good accumulation along the 600 week simple moving average (SMA) which is then followed by a $100 spike in the gold price. This would push the 2018 gold price to near $1,500. 

With Trump positioning him self to do well in the mid terms, tariff talk, lower dollar, higher wages, more manufacturing, higher inflation risk (Wall street inflation is moving to Main street inflation) you can expect the current gold trend trend to continue. Add to this the unknown from the petro-dollar shake up from the Chinese Yaun/oil/gold contract go live at the end of March 2018.
