On June 24 2015 there was a USD rally after the uncertainty with Greece and the EUR zone. One of the most prominent moves was on USDCAD. As we were getting ready for the Asian session, the pair showed exhaustion signs on the hourly chart. There was also a longer term resistance right around that area, which further confirmed that the pair was about the go south.
Three bars with huge bearish wicks appeared on June 19 2015 after a rally. This signified that the pair had hit a strong rejection/resistance area. I shorted aggressively for this being a very strong short signal. Took quick 6-7 pips but the trade was good for a lot more. However, there was definitely a cluster to the left (not shown on screenshot) and I had to be conservative with the T/P.
As always, trades like this one require a lot of experience and a good ECN broker.
