GBP/CAD Add to Sell Trade

I'm already short this pair, and looking to add to it. I know it's been in a wild, savage upward trend, but it has begun to miss daily pivots - with today's being the most recent. It looks like the pair will close today below the daily pivot, and that's bearish for me. If we can then get bearish Knoxville Divergence or a bearish reversal tab, or just a solid break lower (after missing the daily pivot) then I want to add to my sell position.

My target is at least 1.8000.
