An institution-specific seat can open multiple block trading accounts, but the specific number may be limited by exchanges and regulatory agencies. In Chinese mainland exchanges, such as Shanghai Futures Exchange, Dalian Commodity Exchange and Zhengzhou Commodity Exchange, only 1-2 block trading accounts can be opened for an institution-specific seat at most.

Only by opening a 1-2 block trading account can we effectively avoid the cross-influence of funds and risks.
