Psychology...

The bears are in control for the 1st two days of this formation. However, the high on the 3rd day trades above the close of the previous day. And, a strong upward opening gap appears the last day. Since the last day closes at a new low, then this is the perfect opportunity for shorts to cover their positions. Strong short covering should propel the price upward in the coming days.
