I don't really like how the margin trading page seems to be based around automatically borrowing money , this makes it kind of difficult to buy with my already borrowed funds.

Also the page is no longer showing my 'margin reserved' even though I have a large amount of unused borrowed funds, is this because the 'position maximum period' is under 7 days technically since my loan was filled last night so the loan expires in 6 days 18 hours or something?

I think I left some room for interpretation in my question, so just to be sure: I was talking about funds in the "deposit" or "exchange" wallet of the same person.  Is it still bitfinex that would take the loss then?
