- Spread — the difference between the buy price and the sell price, which you already know. You pay it once per trade.
- Commission — a fee to the broker for the trade. Some charge it separately, others hide it in the spread.
- Overnight fee — charged for every night a CFD stays open. It’s as if the broker lends you money and charges interest for it.
An example with made-up numbers; every broker has its own. The overnight fee is 0.02% of the trade. A $1,000 trade with leverage of 10, margin $100. That’s 20 cents a night, $6 a month. Add the spread, say 50 cents, and it’s $6.50 in total. That’s 6.5% of your money, even if the price stood still.
