The reasons for the difference between the consignment price and transaction price of rebar futures are:

1. When participating in call auction, if the declared buying price is higher than the transaction price generated in call auction, or the declared selling price is lower than the transaction price generated in call auction, the transaction price generated in call auction shall prevail.

2. When participating in continuous bidding, when the declared price of entrusted buying is higher than the lowest declared price of immediate selling in the market, the lowest declared price of immediate selling is taken as the transaction price.

3. When participating in continuous bidding, when the declared price of entrusted selling is lower than the highest declared price of immediate buying in the market, the highest declared price of immediate buying is taken as the transaction price.
