BUX guarantees that you cannot lose more money than the total amount that you invest by taking two precautionary measures:
1) We will close your position the moment you have lost 100% of your invested amount. This is also referred to as a "guaranteed stop-loss".
2) We are “Ring Fencing” a certain amount (see: What is the Ring Fenced amount?). This is still an amount in Cash, but if you have open positions it will be reserved to pay for possible closing Fee and/or Financing Fee.
We do this to make sure that your account will never go into negative and therefore we will never require you to deposit more money to cover for losses. Let us know if you have any questions about this by sending us a chat message or mailing us at email@example.com
