Leverage means borrowing. If you buy a product with a leverage x2, you can borrow the corresponding amount for which you invest. It doubles your chances of winning, and it doubles possible losses.
Example:
If, for example, you have a leverage factor of 2 (= 200%), you will be able to gain a profit for every hundred kroner invested as if you had invested two hundred kroner. But if the market falls, you also get double losses.
The leverage factor is usually set on a daily basis. It is important to be aware, because it means that the return over time can deviate significantly from the leverage factor multiplied by the underlying return.
Daily adjustment of the exposure is necessary to maintain a fixed daily leverage factor.
NOTE! The risk of leverage is very high. You need to be prepared to lose all your invested money.
