A Megaphone at 4-hour chart may signal the bearish breakout and a beginning of a downtrend at the USD\CAD. Price has finish 4 touches at the trend lines of the Megaphone and it is expected to create a partial rotation, reverse and break the support trendline. Megaphone is based on the 1.0400 Support level which is a strong psychological level - once the megaphone is broken we could expect this level to break as well.
