The VXX Oct 15th $27C which was entered on Sep 17th @ 2.10 has been as high as 6.70 on Sep 20th, but has come all the way back down. What is notable is that VXX has not had enough strength to get out of its week-long horizontal channel. When and if it does adding to or initiating new positions should be considered, but until that trading range is broken to the upside, QQQ puts are the better choice for an extended market decline.
