Forex technical analysis: USDJPY buyers have a decision to make…

Can we get and stay above the broken trend line and keep the momentum going. 
The USDJPY was banging against the 100 hour MA for 8 hours today (blue line in the chart below).   ON the downside, a trend line on the hourly chart was also holding support. Something had to give. The price broke to the upside. The price pushed higher (see chart below).
