The USDX made a strong pullback around the level of 100.24 as the Fed Yellen's speech produced that kind of volatility. We can see a test of the 200 SMA on the H1 chart in coming days, because the index can perform a rebound over there towards the resistance zone of 100.24. We should remind that a breakout above it will open the door to the price zone of 101.00. The MACD indicator is at the negative territory.
