short USDMXN adding to on break of trend line

USDMXN has been on a savage tear the last 2 weeks. It has printed multiple Knoxville divergences as well. Using pivot points and trend lines, I shorted this on break of the last trend line. It now has 2 missed weekly piots, and 1 unhit weekly pivot. I want to short again on a break of the current trend line (which should also make it hit the weekly pivot). Ideally, I want to short it all the way down to the monthly pivot, but I may be satisfied with 19.0.
