The US dollar index is above critical support levels as it continues to trade sideways waiting for the FOMC rate decision and Fed chairman Janet Yellen's speech.
The price continues to trade inside the upward sloping wedge. It is above the Ichimoku cloud in the 4-hour chart, but has broken below the kijun- and tenkan-sen indicators giving us a bearish signal. A breakout below the cloud and out of the wedge will also be a clear sell signal.
