Dubai Down Day: Buy TNA

Usual DISCLAIMER. The day was marred by the developments in Dubai and by increased margin requirements for leveraged ETFs. Two TNA Buy Signals flashed at the end of the abbreviated trading day: R FACTOR BUY TNA and TZA ABSORPTION EMV BUY TNA. Absorption is reviewed in Williams's excellent book on volume: http://www.esnips.com/doc/8ebeca88-7efa-49ea-841c-86e27f212b55/The-Undeclared-Secrets-That-Drive-Stock-Market#
The latter signal's formula is =AND(FD273>1.15,EY273100,EY273<(FA273+0.67*(EZ273-FA273)),EY273>(FA273+0.33*(EZ273-FA273)),FS273>0). Modifications include TZA daily ease of movement (FS), TZA candlevolume EMV (GO), and TZA daily volume/prior day volume ratio (FD).
