Back below 112.50 once again

Does anyone know why 112.50 is being such a pivotal level? The PA around it is quite extraordinary if you ask me.

What's great about the level is that it's giving a great opportunity to trade a break confirmation if you miss or are stopped out by the initial break. The 112.00/10 area remains the next big support point.

This particular move looks yen led as the crosses are slipping too and that's helping to drag the euro down through support at 1.0730, and cable's lost a quick 18 pips too.
