Bitfinex - Margin trading - long/short ?

[rolli]

Hy,
When I buy on bitfinex with leverage - is it

-leveraged trading - meaning I buy with borrowed money and price has to go up until I close the position, so I can sell with profit?
or
-the buy is only executed when the position is closed - so price has to go down until i close the position to make profit?

P/L % in Bitfinex shows the actual profit - what does Swap mean - when I buy BTC with borrowed USD, where is there a swap?

Thx

or is it:

-margin buy is executed only "on the books" and when position is closed on the market?
-what does swap mean?
