First things first, the VXX stochastic Buy looks likely to trigger on the close. However a recovery of today's 400 point decline in the DJIA could forestall the trade for another day, or longer. The DJIA has already come back 125 points off of its low. But stranger things have happened in this robot controlled trading environment. VXX gapped higher to $19.04 after the Open and has backed off to $18.45 as the morning's low. It is currently at 18.70, about mid-way between the two levels. A break above 19.10 will be the trigger to buy VXX calls, Dec 20th $19C (should be 1.50 or less). If VXX $19.04 holds, there is no trade today.
