When the TWSE auctions listed securities pursuant to these Regulations, it may suspend open bidding for the auctioned securities during auction period (except for those tendered by Securities Finance Enterprises to effect settlement or return securities). The volume of auction consignments shall not be subject to the restrictions imposed on regular transaction consignments. The auction transaction price shall not be subject to the fluctuation restrictions imposed on regular transactions. With due consideration, the TWSE may also decide not to set the auction transaction price as the opening or closing price that day. The volume of securities transacted may also be calculated independently of regular transactions.
