In the data window on the top left corner of the chart the second from the last reading is "%K 15.21" . When that reading exceeds 20.00 we will have a confirmed VXX Buy Signal. That %K is up from 10.89 on Friday, so extrapolating, a market drop of 300+ points should "move the needle" enough to generate the Buy. Stand-by to buy the VXX March 20th $14.00 Call currently at $1.10-1.15.
