In the Trading Agreement, available here: https://www.dukascopy.com/swiss/docs/ban ... in-use.pdf
there's a clause:

3. Client’s Obligations
3.1. The Client shall be obliged:
....
(ii) to compensate Dukascopy Europe for any and all fees, taxes, losses, expenses, disbursements and commissions incurred by Dukascopy Europe in connection with the performance by Dukascopy Europe of its duties under these Conditions;

Could anyone comment on that? Can anyone explain in layman's terms what it is the Client obliged to pay besides whatever listed in https://www.dukascopy.com/swiss/docs/ban ... ariffs.pdf ?

(The above links and quotations relate to the Dukascopy Europe agreement, but the Swiss Dukascopy agreement has the same clause).

Well, I understand that trading implies risks, and if, say, a position is closed with loss, then the loss is the Client's; it's ultimately the Client who is losing. But what other expenses may the Client have to cover besides that?

If anyone from the legal department read this forum, could you please shed some light on the issue?

Did anyone actually have to cover any expenses, besides his/her own direct losses or whatever listed in the Tariffs.pdf (like volume commissions)?
