TFX adopts a segregation scheme of customer funds for protection of customers. Under this scheme, each TFX member deposits its customers' margins with TFX, separately from the member's own margin. On this basis, TFX takes custody of each member's customers' margins and the member's proprietary margins separately.

Give-up is a mechanism that a certain financial futures contract is executed by one member and clearing (including handling of margins and profit/loss) of the said contract is undertaken by another member. TFX is the only exchange adopting a give-up mechanism in Japan.

A member who is instructed by a customer to execute a contract is called an executing member, and a member who is instructed by the customer to clear and settle the contract is called a carrying member. By utilizing give-up, a customer can concentrate clearing of its contracts to a specific member, assign execution and clearing functions to the different members respectively, or diversify its positions to multiple members.
