1. Settlement reserve: generally speaking, the funds paid by member units to the exchange according to fixed standards are prepared in advance for transaction settlement.
Settlement reserve refers to the funds prepared in advance by members in the special settlement account of the exchange for transaction settlement, which is the deposit not occupied by the contract. The minimum balance of the settlement reserve shall be determined by the exchange. The minimum balance of clearing reserve for members of futures companies is RMB 2 million, and the minimum balance of clearing reserve for members of non-futures companies is RMB 500,000. If the balance of the member's settlement reserve fund is greater than zero and lower than the minimum balance of the settlement reserve fund, the exchange will issue a notice of additional margin through the "member service system", and members are prohibited from opening new positions before the margin is replenished; If the balance of the settlement reserve is less than zero, the Exchange will issue the Notice of Additional Margin and the Notice of Compulsory Closing through the Member Service System. If it is not filled before the market opens on the next trading day, the Exchange will force the liquidation of the member according to relevant regulations. Calculation formula of settlement reserve: balance of settlement reserve on the current day = balance of settlement reserve on the previous trading day+trading deposit on the previous trading day-trading deposit on the current day+actual offset amount on the current day-actual offset amount on the previous trading day+current profit and loss+current deposit-current withdrawal-transaction fee+other funds, etc.
Second, the trading Margin is the self-provided funds that investors need to pay when financing to buy securities in the securities market.

The bidding transaction of central grain reserves also needs to pay the corresponding deposit, generally 5 yuan. After the transaction is completed, the deposit is paid to the trading center as a handling fee.
