（1） Margin system The minimum trading margin of an egg futures contract is 5% of the contract value. The margin for newly opened positions shall be collected as the trading margin at the time of settlement on the previous trading day. The trading margin shall be managed at different levels. As the delivery period of futures contracts approaches and the amount of positions increases, the Exchange will gradually increase the proportion of trading margin.

（3） The position limitation system refers to the maximum amount of a certain contractual speculative position that members or clients can hold according to the provisions of the Exchange and calculated unilaterally. The same customer has opened multiple transaction codes at different futures company members, and the total of all positions on each transaction code shall not exceed the position limit of one customer.
