Ahead of the BoJ rate decision tomorrow, USDJPY sold off heavily today on a somewhat unprovoked move...did someone get wind of the decision early? Either way it has created a bunch of space on the chart and may make it difficult to find level early tomorrow morning.
The BoJ are expected to hold at -0.10% so it may be the press conference that provides the fireworks. This is all likely to happen before London gets underway so be sure to revisit the levels pre-market to set up for any continuation move as we open.
