WTI forming the 4th leg of a terminal

There is some reason to backup the idea that WTI is forming the 4th leg of a terminal pattern:
1. The current drop cannot exceed 55.05, otherwise the idea failed;
2. The minumum drop length is met, yet the time not;
3. After the 4th leg finished, the dotted trendline can be put at a right place;
4. The 5th will be violent, at least the length of the blue rectangle;
5. Wait for chance to close the current short position now and enter a long one next 10 days;
