So this is one of the oldest patterns in the book (which I learned from an old binary trader) called the 3 Point Reversal. Essentially, It's just a weak or bottom. In this situation, the buy signal is when the price action crosses the "B" price level in the direction that would constitute a reversal.
In this case, the price has crossed the B level with strength, and now its a safe time to get in after the profit taking and consolidation. I'm going long as soon as the markets open today. This also matches with the overall strength of the dollar right now.
