Trying USD/CAD long once again

I was stopped out of my last attempt at going long USD/CAD. Price has dropped another 700 pips since then, reaching another level of support so I'm giving it another shot.

Entry: 1.2550
Target: 1.32
Stop loss: two daily closes below 1.2450

On the daily chart below, note that price is sitting on another confluence of good support. I'll exit on two daily closes below the lowest trendline.
Zooming in to the chart above, you can see a clear 5-wave decline. This indicates that the larger trend is down, and after a brief rally, there could be continuation to the downside. However, note that wave 5 is an ending diagonal. This tells me we'll see an explosive rally soon.
