From a technical point of view, on a daily chart, Dollar Index is trading within a bearish channel and is capped by its declining 50-day moving average (in blue). The daily RSI stands within its selling area. Readers may therefore consider the potential for further weakness as long as 92.55 is not broken to the upside. The nearest support would be set at December bottom at 90.50. A second one would be set at March 2018 low at 88.90.
