This is a bullish chart of the US dollar futures /DX in a daily timeframe
View attachment 7512
The dollar has broke out of the bullish falling wedge; an uptrending channel and is busting through the 50 ema at the presnet. Notice the run took off shortly after the RSI neared the value of 30 (oversold). There is a bullish cross on the MACD and the histogram is sloping up. First target of real resistance is the pink line coming in near 77.6
Based on this chart alone; I expect some weakness the first part of this week, possibly until Wednesday or Thursday. Then when resistance is hit, I expect a counter reaction, the US dollar to drop, and the Christmas rally to begin. The SPX could trade down to around 1065, but I don't see it going much lower. Of course you know this is just pure guessing, as IMO nobody really knows where the market is really going near term. Trade Carefully.
