An e wave is the last of five overlapping waves that make the triangle. They are generally labelled a,b,c,d.e. Capital letters can also be used. At least 2 of the alternating waves are related by the Fibonacci ratio of .618 That refers to waves a and c, waves b and d, or waves c and e. In this triangle wave e is .618 times wave c at 13 1/8.
The a wave went from 14.25 to 12.375(12/7). the b wave went from there to 13.875 on 12/10. The c wave then went to 12.68 on 12/14. The d wave went to 13.87 on 12/15. And the e wave has gone to 13.125. We don't know for sure the e wave has ended. If may have a little further to go, or it very well may have ended today.
