A Hidden Pivot support at 1218.70 sits just beneath the all-too-obvious low at 1218.90 recorded on August 18, making it an enticing spot to try bottom-fishing.  It would almost surely be read as a breakdown by most other traders and chartists — and it would be a breakdown, except that we have a logical and precise place to look for the whipsaw to commence. Accordingly, I’ll suggest bidding 1218.70, stop 1218.30, day order. It it fills you’ll be on your own. Alternatively, I’d need to see a print today at 1235.70 before I’d start thinking once again about that not-so-ambitious rally target at 1244.20.  _______ UPDATE (10:37 a.m. EDT): The trade was a small winner, since the futures took a $3.10 bounce overnight off an interim low of 1218.40.  It was an hour later, however, that a final, wicked swoon created a true bottom at 1211.70 that gave way to a powerful $26 (so far) thrust.
