I'm not sure I know how to answer all of your questions, but this might help.
ETF's in general require extra fee's to pay the people who create and manage them, in the example above this would be the Proshares people. Leveraged ETF's require higher fee's because the amount of time and energy people need to put into them is higher. This extra time is because they involve derivatives that need to be swapped out or managed daily. This is one of the reasons they are typically for day trading. The other reason is because if you can go up 2x faster, you can also go down 2x faster.

In your example, a lot can happen in 6 months and if 10% is your goal there are less volotile ways to go about trying to get it. Expense ratio is what it cost the fund to manage the ETF. Its like a business expense of the fund. There are unique expenses with ETF's that you obviously already know about, but I couldnt tell you specifically what they are. If you want to know how much you'll make you gotta know what those are and factor them in. Also, each fund is different.

$10,000 bought.
Falls to $8800
$10000 - $8800= $1200 loss
$1200 + $14 commission = $1214
$10000 - $1214 = $8786 Left in your Account, less whatever fees unique to the ETF you traded.

For the other one its a thousand dollar gain minus fourteen bucks and the ETF fee's, whatever they may be.

HungryWallet, the calculation that you post is not what I was looking for. what I wanted to know is the missing part of the equation that you have there, the "fees unique to the ETF you traded"!
let me be more clear, I need to know how to calculate those cost and what information I exactly need to calculate them, as I mentioned the brokerage says UCO is Subject to Higher Maintenance 22%, what does it mean 22% of what? does number of days that you keep this ETF has effect on fees or it does not matter if I sell it today or 6 month later? if it does matter then what numbers should I have and what formula I have to use for that?

let me make my question even more simpler! assume that I had closed my eyes and bought 10 unit of an ETF "Foo" with 2X leverage for 1$ each and I have no idea what it is I only know that price of the ticket "Foo" at the buying time was 1$, then I keep it for 6 month and the ticket "Foo" price now (after 6 month) is 2$ (let's say brokerage commission is 1$ for each trade)
so I paid 10+1$ to buy then I would have 20-1$ after sell, so gain would be 8$ if there were no fees but obviously there are and I need to know how much will be deducted from that 8$ (I am not talking about tax, I meant just fees) I mean what numbers are involve in this that I have to ask or figure out for "Foo" itself or brokerage disclosure.
