Shawn,
Our observation is that the timeframe that really matters intraday for the 20 DMF is the last 30 minutes of trading. It can turn the day MF on a dime. So at this stage you must make a bet that the long exhaustion scenario will develop until the close and that buy programs will be switched off. The price of the bet is the stop you choose.
For full disclosure, I already made the same bet as you entering TZA at 35.66 with a tight stop at 34.87. Be careful at the open tomorrow, Markettells just issued statistics for the day prior to Memorial Day Holiday with a very high percentage of historical occurences closing in the direction of the open. Volume will be low and likely unable to make a big inflection in price after the open. So, respect your stop if it is hit and we open higher tomorrow.
