The 111.00 area was key support on the way down
The surge higher in the USDJPY has the USDJPY approaching a key technical target around the 111.00 area.
That area was defined by the swing low on February 11 at 110.98, the swing low on Feb 24 at 111.03, and the lows on March 17 (see 4-hour chart below). Although the price fell below the level on that date, there were no closes below the 111.00 area. There should be a cause for pause against the level(i.e. some profit taking selling and perhaps outright selling). However, the market price is in the midst of a pretty good trend move higher. As a result, do not ignore a break. The next key target on a break will be the 200 bar MA on the same 4-hour chart at the 111.215 level.
