why I'm short usdjpy medium term, on fundamentals and technicals

Today we got a lot of fundamentals for Japan and the US. Japan's rate policy was unchanged and it remained in -0.10%; United States' leading indicators of Chicago Purchasing Manager's Index and Consumer Confidence disappointed coming out at 50.3 vs 55 consensus and 111.8 vs a consensus of 112.5 respectively. On top of that, US GDP disappointed with a 1.9% vs a 2.2% expected. I want to be clear this is medium term since in the long run the US is one of the strongest economies relative to it's developed peers even with those numbers.
Technically, USDJPY just broke all of it's retracement levels from last couple of weeks and got back into it's long term downward channel, giving enough signals it plans to continue down.

We did in fact go lower since this idea was posted, so the medium term mention seems to be over.We also seem to have reached a bottom, it is still weak but it the uptrend seems to be getting confirmed. Here's what I'm following now, fundamentally long and in between the bottom of the trend lines, looking for the channel to be confirmed to be more conformable with a longer term long.
