Yes, funds also have call auctions. The trading principles of call auctions are the same as stocks. In collective pricing, the computer transaction processing system sorts all declarations according to the principles of price priority and time priority. When matching transactions, the following principles are followed:

1. Maximum trading volume.

2. Buy orders higher than the benchmark price and sell orders lower than the benchmark price are all satisfied (transactions are completed).

3. One of the buyers and sellers with the same price as the base price declares that all are satisfied (the transaction is completed).

At the same time, investors can receive declarations or cancel declarations from 9:15 to 9:20, and investors can receive declarations from 9:20 to 9:25, but cannot cancel declarations.
