Market expects the Fed to raise rate between March and July 2015, and the dollar will keep rising as long as the expectation does not change. Once that time frame arrives, dollar index should be around 88 - 89 coincident with the blue resistance line from 1985. Dollar will go lower from there as the Fed cannot actually raise rate because the market already raised the rate for them because of the expectation.
If this script is right, expect rate to keep rising, and expect the ongoing pressure on gold and commodities, until next March-July.
