Property Value

If an account goes below it's minimum balance (and Pre-Trade Risk management is enabled) then the account will only be allowed to submit orders that will reduce any positions it has. New positions cannot be opened.

This value is also used to determine the amount of money available for margining (Max. Margin = Balance - MinBalance), so a positive number would reduce the amount of margining available, whereas a negative value increases the amount available (like an bank account overdraft).
