It is always a good time to short the US dollar, as in my last post, USD is looking like the Euro of 3years ago. Now as far as USDCAD , our SW short signal came on July 21st, if you held through the pull back you would be up +430 Pips today. You had a great second entry on August 31st, and it has been straight down. Now do we keep going lower or do we pull back, no one knows, if you do short here, make sure you have a plan, will you hold through a pull back, or take a quick loss and wait for next setup, and what is your plan for taking profits.
Back to your original question, " is it too late" personally I would wait for a new setup
