USDJPY 4h

Almost perfect Double top + divergence was formed on USDJPY which is very well known formation for all TA traders. The key is that this is a psychological level of 150.0 where last year Japanese officials intervened to support JPY. In the last few hours by looking on 4h chart Longs pocketed their profits. Big sell off on the way. Is it because of double top or another intervention to bust up JPY which is wildely expected anyway?
