August 2013 occurrences of Hindenburg Omen yield my best guess of the next market crash (based on the 2008 relationship) as Tuesday November 19, 2013.
Hindenburg Omen August 2013 had 5 occurrences between July 31 and August 12 (which is not included). I use a random date of August 9 and add 74 trading days based on the experience from 2008. This comes to the best prediction of a crash on November 25, 2013, about two month from now. (For consistency, if I knew the actual trading dates, I would use the third one (out of five) and begin the count from there). A better guess is the third trading day being Monday August 5th 2013 (rather than August 9, 2013). Therefore, subtracting four trading days would now make the best prediction four trading days earlier or Tuesday November 19, 2013.
