When accepting an order to trade securities listed under the altered-trading-method category, a securities broker shall take full delivery of the funds or securities before making trading quotes.
When an institutional investor or government fund represented by a custodian institution places sell quotes for a single security listed under the altered-trading-method category, within a cumulative amount on the same day of less than NT$50 million, it may be exempted from the provision of the preceding paragraph.
By public announcement of the TWSE, the periodic call auction trading method may be imposed for securities referred to in paragraph 1. In periodic call auction trading, in principle, matching operations will be conducted approximately once every 30 minutes by manually controlled matching terminal, and the matching schedule may then be adjusted depending on the trade activity in response to the public announcement.
The measure of requiring full delivery of funds or securities under paragraph 1 is not applicable to the trading of securities listed under the altered-trading-method category in a default-handling account, call (put) warrant liquidity provider account or call (put) warrant hedging account (excluding accounts whose number begins with 929); also, the measures of paragraphs 1 and 3 are not applicable to after-market odd-lot trades.
