We do not charge margin-trading fees per se. You can trade with leverage as long as you keep Margin Utilization below 100%.
In case you exceed 100% of the margin, there is a fee equivalent to 100% p.a. on the exceeded value charged daily. To reduce margin utilization, we might close your positions manually. The fee for manual execution in case of a margin call is 90 EUR.
The fees for exceeding the margin are set for each margin call occurred and are charged daily. The fees for the upcoming weekends are charged on the night from Wednesday to Thursday.
