My initial estimate of the rally high date is 4-8 days, as early as the 22nd and as late as the 28th. I'll go short starting the 22nd at 38% retracement of the decline. On the NDX that's 2254. Until then I'll post infrequently.
I'll use SP futures 30-minute close .5% below it's 92-unit M/A as a fail-safe on this rally.
