I see you failed to add a trade acceleration trendline, which pretty much is a more vertical trendline you are missing on your drawing and which makes up for that asc. channel. Whenever a commodity/pair have an acceleration trendline, the greater the odds of a break down. This is just what happened to OIL and Aussie.
Your trendline that you added looks to me as a SPEEDLINE. You add a second SPEEDLINE, you get the minimum target one is looking for.
One more thing, I don't see any basis for the desc. channel you have drawn other than the S/Rs involved that could "hold" price for a while.
I observe that you enjoy the EW theory very much. I just recommend that you be very carefull and know exactly what you are doing.
Like I said before, price doesn't always return to "check" back at the broken line.
