We can spot there are three price push-ups starting with 17th Dec afternoon. The first two times can be seen as a temporary double bottom. In terms of each time's shaking fall, it's likely the whale is absorbing the chips. Now the support is still in the previous midpoints(430) meanwhile formed two hammers when it is hit. The next rise should be cross the midpoint of this new range (around 430-445), and better to stand above 445 when it finished the soar.
