Hindsight is always crystal clear.
The EWDTer, upon seeing JSL's analysis, the "Not Confirmed" Sign and the development of Subminuette Waves 4)c.c:ai and ii, sold short on Thursday evening or at Friday open.
He had in mind that Subminuette Wave iii should be stronger than wave i and wave iv should be the same size as wave ii (~30,5,10) and he would get out of his position if the Market didn't act as he guessed.
As it turned out, the Market tumbled into wave iii and then rebound as wave iv, in the mean time our EWDTer was sweating measuring the length of wave iv, praying that it did not overshoot his stop. Then the tide turned in his favor, wave v began and showed multiple lower lows. He did not relax then, because ROC decreased confirming that it was wave v which could be shortened. He counted Microwave .i,.ii,.iii,.iv, and v. The Market turned up, he didn't want to be whipsaw into an elongate wave v, so he waited for a higher high, willing to give up some points. The Market continued to unfold Infrawave v:iii, v:iv and v:v. "Which way to go from here?", the Market asked itself.
13,222.4902 1452.1899 2557.1299
Previous waves ii and iv.
13202.2305 shattered
................... 1452.55 2554.8 ?
13116.1504 1441.75 2522.649 ?
Our EWDTer saw that it was closed to JSL's measured move and
the series of previous ii and iv. He didn't want to risk a ~6,-.37
,2.3 points gain with ~140,14,23 points loss equal to Subminuette Wave ii.
So he got out of his short position and switch into wrong position.
Quote from JSL_Capital:
We amateurs have our days too 
11:30 was a good time to close any morning shorts along with capitulating Eurpeans (also 53-55 area coincided with measured first and today's volume indicates it's possible that we bounce to the low-mid 60s area on ES at least. If the A/D doesn't tick up along with price though, we might get another round of sell off in the afternoon, but geez these bulls are buying the dips like crazy!
