Margin trading
CFD's, futures and Forex are traded against margin. The margin consists of the money on the trading account +/- unrealized profit / loss of open positions. Margin trading lets the trader have positions that are several times bigger than his own capital if he so wants to. This so called leverage makes it possible to make big profits / losses compared to the traders own capital tied to the positions. The margin available to the trader changes when the market prices moves; if the price moves in favour of the trader's position the available margin grows and if the positon goes against the trader the available margin becomes smaller. It is important that the trader has enough margin to cover his positions at all times. In case the trader's available margin falls below the total margin requirment of his open positions, all his positions will be closed automatically at market prices (so called "margin call").
A list of margin requirments is available here.
In the example below, a trader whose starting balance was 10 000 Euros has bought 1000 Nokia CFD's at 12.

What does a long-CFD position mean?
What does roll-over interest mean in Forex?
For positions left open overnight, industry standard “rollover” interest, based on short-term interest rates, is either charged or paid, depending on the direction of the trade vis-à-vis the interest rate differential between the currencies that make up the position.
The positions are automatically rolled over at 5PM EST (New York time).
