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.
In this instance, I will demonstrate a trend shifting trade. I use a customized indicator with RSI and a 21 EMA plotted. When the EMA crosses RSI from below, there is a possible bullish trend shift and vice versa: when the EMA crosses RSI from above, it's a possible bearish trend shift. I only use the cross as a confirmation, I don't blindly rely on it! Please use the Internet to familiarize yourself with RSI and the concept of moving averages (EMA in this case).
