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.
