Is that the end or is there more to come?
I'm going to take the scattergun approach to this one and note the levels around the various pairs.
USDJPY
Stopped on a dime at the broken descending Jan 3rd thru Jan 27th trendline and just above the old 112.50 level that's seen so much action recently
Gains likely limited to 113.00 then 113.25
EURJPY
120.00 has held firm, give or take a few pips. The early Feb lows are a consideration if we move back down. Look to the 55 wma first in there at 119.72 and around the broken 38.2 fib of the Oct 21st swing up
Next decent support isn't until 118.35/50 area, being a support level and the 50.0 fib of the Oct 21st swing up. We do have the 100 dma at 119.14 so we may see some action there first
The 100 H4 ma at 121.14 has been doing a good job as resistance these last few days. 120.50 and 121.00 will be the immediate resistance levels
GBPJPY
The low 139's to 138.90 is where I'd look for the main support if 139.50 breaks. That level is support as well as the 200 dma
The 55 dma at 142.82is the main resistance point should we retrace all of this move and more. Again, stick to the half and big figures on the way back up
