US Dollar Index: Greenback bulls are alive as 93.20 support is holding on

• US Dollar bulls are forming a base in the 93.21-93.66 area as their objective is to break above the trendline and regain the 94.00 level. 
• US Dollar Index (DXY) has gained about 5% since mid-April and the current move down is seen as a bull flag or pullback for bulls.
• However, a strong bear breakout below 93.21 swing low can invalidate the bull flag theory and lead to a retest of 92.81, 38% Fibonacci retracement (mid-April-late June bull run)
