Dear developers,
Real-time quotes for the ruble (RUB) can currently not be obtained in the market. However an exchange rate is determined once a day by Commerzbank's foreign exchange trading department. As a result there are significant settlement risks. The conversion of the amount set out in your order may therefore possibly not be punctual or at a market rate. Hence there is a risk that, in the worst case, the exchange rate could be zero in which case you would suffer a total loss. Commerzbank accepts no liability in this regard and for any damage resulting therefrom (with the exception of damages resulting directly from willful or grossly negligent conduct).
Thank you for your understanding.
Your Commerzbank Support-Team
