Operating method:

1. When the trader transfers, rescinds or terminates an electronic trade contract, the Exchange will deduct general expenses that the trader should pay, make a settlement for transaction profit and loss, and return the trader payment for goods or performance bond that the Exchange collects on behalf of the trader.

2. Content and method of settlement by the Exchange for each trader are as follows:

The current day’s account balance = the previous day’s account balance + the current day’s fund inflow - the current day’s fund outflow + the previous day’s performance bond -  the current day’s performance bond + the current day's transfer profit / loss + delivery profit / loss + sales revenue - purchasing expenses - transaction fees - delivery fees ± compensation fees for delayed delivery. Transfer profit / loss = (selling price - buying price) × transferring quantity ÷ 1.17

Delivery profit / loss = ∑ (ordering price of seller- delivery settlement price) × quantity sold ÷ 1.17 + ∑ (delivery settlement price - ordering price of buyer) × purchasing quantity ÷1.17
