Usdcad short continuation

I'm short biased on the daily and today's price action at the top of the trend line gave me the opportunity to take a low risk trade as I was able to tell that the volume came in at the upper tip of the pin bar. I'll be looking for shorts again if prices can rally back up to the source of this down move. I would like see price move in a stair case fashion on the 5 min into the sell zone
