Hi Oliver,
As I thought, the Minimum equity protection has been activated. This shows the account balance is below 888002. You need to make adjustments to Max spread, Minimum equity, and Maximum daily loss. You can set these to zero to get the account trading but you won’t have any protections. If this is a prop firm you can get these protection level requirements from them. If it is a brokerage account then you need to decide what protection levels you are willing to accept.
