The decay factor only applies if you hold them overnight. However, intraday, there are also discrepencies depending between 2X, 3X and underlying index.

One more thing. URE closed at 3.43 and a penny move there is a much bigger percentage of the trade than in SRS. Any slippage and commission will be magnified. Also any move is slower to come. If instead of SRS short you took URE long today on the 15 minute, you would have made 1.7% vs. 2.5% (assuming no slippage or commission). Difference would have been larger with slippage and commission.

I see.  Thanks.  I suspect that there are some like me that have to buy URE anyway.  I trade inside a SEP IRA and cannot short.  So when SRS or FAZ trigger short I buy URE or FAS.  Thank God for short ETF's.  I would not have made much money last year without them. 

Why not open an account at IB. If a short triggers and no shares at TS - then do the trade at IB - have it "prepared" to go as the MA's get close. Once the trade occurs - you can place stops if you use stops. You also could get Trade Bullet to execute automatically. I don;t yet use trade bullet but have had no trouble getting short when TS signals the trade. I simply at that moment set my price in IB and let it go. RARELY if the price moves away from the "entry, it will not pick you up so long as you don't have a bunch of time in between the trigger and when you place your IB trade. If you do this - you still have the TS automation. Also, chances are reasonable that if you do not put the $25K at IB to give you day trader status, you probably won't have so many SRS trades that you will get caught in the 3 day (or 4 day - whatever it is) rule. This was the 1st short trade on the 15 min system since June 25.
