Recently I have begun looking into ETFs which are Exchange traded funds. They have etfs for short oil, short gold, long oil, long gold, 2x's short oil, 2x short gold, etc.

Basically you can use the power of leverage to take advantage of short term wings in both commodities as well as the markets in general. Of course there is also risk involved.

Just wondering who here day trades these etfs?

Here are some examples:

I've traded them before, there's a lot of money to be made of course & the markets can be predictable if you know how to correctly anaylze news & headlines. I recommend gaining experience trading in another market before diving into ETFs.
