What negative balance protection means in practice
In fast markets, prices can gap through your stop-out level, leaving an account with a balance below zero. Without protection, a broker may pursue the client for the shortfall. With negative balance protection, the broker resets the account to zero and absorbs the excess loss. Protection may be a regulatory requirement in some jurisdictions, a discretionary broker policy in others, or absent entirely. It may also apply only to retail clients and not to professional or wholesale clients, and it can exclude certain account types or circumstances. These distinctions matter, so read the exact wording rather than relying on a summary.
- Protection typically caps losses at your deposited funds, but wording and scope vary by broker and entity.
- Some regimes mandate protection for retail clients only; professional clients may be excluded.
- Discretionary policies can be changed or withdrawn, unlike regulatory requirements.
- Stop-out mechanics and margin calls are separate from negative balance protection and should be checked independently.
