Fundamentally speaking, there is a chance that USD could be dropping lower if this month's CPI prints a lower number than the previous month's number. Furthermore, combined with CAD fundamentals that starting to align with Oil price fluctuation provide a quite stable CAD outlook.
In terms of technical perspective, a big rejection candle that is present on top of the marking area provides a signal that a continuation to the downside is quite possible.
In conclusion, as long as the price did not move higher and close higher than the high of the rejection candle, a short position is preferable.
