Please read up on how the mathematics of these doubles will grind your account into dirt. The maximum time you can own these is one week

I respectfully disagree. First look at the chart on 2X or 3X short. Ain't pretty is it? Top left to bottom right. But I have made money on these. How? The maximum time you can hold these is hours. maybe a couple of days. I will sometimes buy on Friday afternoon to hold until Monday morning if "news" is expected. So you can hold it . . . like radioactive Kryptonite. Sell it if it starts to tank. But sometimes the market starts to tank and you have to strike quick to get in and quicker to get out.

Yes, but the OP did not seem to me to be that rapid a trader. We agree that holding these for more than a few days, at most, is hazardous.
