The Brexit and Janet Yellen's indecision on rates have been digested by the market. Now, the prospect of either a Donald Trump or Hillary Clinton victory in the U.S. election isn't seeming to induce any jitters in the dollar index.
The Brexit has proved more difficult and complex than imagined when Brits went to the polls, and the dramatic drop in the pound was evidence that the market was beginning to understand the consequences of the referendum decision. However, the drop in the pound was not matched by a dramatic rise in the dollar index.
It is inevitable that U.S. interest rates will rise but the timing remains a subject of speculation. But apart from some small, short-term gyrations, there is no substantial impact from Yellen's statements. The real surprise will be when decisiveness overrides indecision but the dollar index chart suggests this is not a high probability in the near future.
As a result, the dollar index will continue to trade within a well-defined trading band. The first key feature on the weekly chart is the support and resistance levels. The support level is near $0.93 and was tested multiple times in 2015 and most recently in May 2016, dipping below but quickly rebounding. This has been a defining support feature since late 2014.
