The "Money Link Express" Super-short-term service is the financing service to automatically purchase and repurchase super-short-term financing products through signing financing agreements. You can designate a current account in the present service area as a "Money Link Express" account, and setup a "Starting Purchase Amount of the Account" and a "Starting Repurchase Balance of the Account"; and ICBC will pre-setup the "Difference of Trade Levels" (indicating the lowest amounts for a single purchase and repurchase transaction) for you. When the available funds balance in the "Money Link Express" account is higher than the sum of "Starting Purchase Amount of the Account" and the "Difference of Trade Levels", surpassed part automatically purchases new financing products according to the integer-time of the "Difference of Trade Levels". When the available funds balance in the "Money Link Express" account is lower than the difference of "Starting Repurchase Balance of the Account" and the "Difference of Trade Levels", the lowered part automatically repurchases new financing products according to the integer-time of the "Difference of Trade Levels" to let the funds of the account back to "Starting Repurchase Balance of the Account".
