Any order for trade value (including commissions)exceeding the cash available in Client's Payment Source Account is subject to rejection. Notwithstanding theabove, if Client places an order with Zero Hash to purchase digital assets for trade value (includingcommissions) in excess of the cash available in Client's Payment Source Account and such order is not
