Article Content

Chapter I General Principles
Article 1     These Regulations are adopted pursuant to Articles 35-4 and 39 of the Taipei Exchange Rules Governing Securities Trading on the TPEx (the "TPEx Trading Rules").
Article 2     A block trade may only be conducted as either a non-paired trade or a paired trade.
    A block trade may not involve margin purchase or short sale.
    The payment settlement of a block trade shall be processed together with other trades made through the automated trade matching system.
Article 3     The underlying of a buy or sell quote placed by a securities firm shall be those securities traded through the TPEx automated trade matching system, and the size, stock type, and dollar amount of a single buy or sell quote shall comply with the following provisions:
  1. The buy or sell size of a block trade of a single security shall be 500 or more trading units. However, if the above quantity is not met but the total dollar amount of a single buy or sell quote is NT$15 million or more, the trade may also be treated as a block trade of a single security.
  2. A block trade of a basket of stocks shall be for five or more different stocks, and the total dollar amount shall be NT$15 million or more.
    If the quoted securities under the preceding paragraph are additional-currency ETF beneficial certificates, the total dollar amount to be quoted shall be converted at the exchange rate posted by the TPEx on the preceding day.
Article 3-1     The quantities of buy or sell quotes for block trades are not required to be single trading units or integral multiples thereof; they may be single shares or integral multiple thereof.
    The permissible price range of a quote for a block trade shall be subject to the provisions regarding price fluctuation limits and tick size set out in the TPEx Trading Rules and other TPEx rules and bylaws.
    The tick size for a quote for a block trade that is within the permissible price range for a quote referred to in the preceding paragraph is 0.01 currency unit.
Article 4     (Deleted)
Chapter II Non-Paired Trades
Article 5     The trading hours for non-paired trades are 9 a.m. to 5 p.m.
    (Paragraph 2 deleted)
    Submission of quotes for non-paired trades is temporarily suspended on all trading days on which no price fluctuation limit is imposed under Article 55, paragraph 4 of the TPEx Trading Rules.
Article 6     The total dollar amount of the buy and sell quotes for non-paired trades placed by a securities firm on a given day shall be subject to the provisions of Article 35, paragraphs 8 to 10 of the TPEx Trading Rules.
    (Paragraph 2 deleted)
    (Paragraph 3 deleted)
Article 7     When a securities broker is engaged to submit a buy or sell quote for a non-paired trade, except where advance collection of funds or securities is otherwise required, the broker may decide at its discretion according to the circumstances whether or not to pre-collect from the principal an appropriate portion or a fixed percentage of such funds or securities.
Article 8     For a non-paired block trade of a single security, the matching priority and trade price for individually placed buy or sell quotes shall be determined in accordance with the following principles:
  1. When a given buy quote is higher than or equal to the lowest previously placed sell quote, it shall be matched and executed against individual sell quotes sequentially from lowest to highest. If multiple sell quotes are identical, they shall be matched and executed sequentially by time priority until all of them are satisfied, or until the given buy quote is lower than any of the unexecuted sell quotes.
  2. When a given sell quote is lower than or equal to the lowest previously placed buy quote, it shall be matched and executed against individual buy quotes sequentially from highest to lowest. If multiple buy quotes are identical, they shall be matched and executed sequentially by time priority until all of them are satisfied, or until the given sell quote is higher than any of the unexecuted buy quotes.
    For a non-paired block trade of a basket of stocks, a given buy (or sell) quote may be matched and executed against previously placed sell (or buy) quotes in order of time priority only after it is verified that the ticker code, unit price, and volume of each stock indicated in the given buy (or sell) quote are consistent with those indicated in the previously placed sell (or buy) quotes.
Article 9     The TPEx will post real-time information on unexecuted quotes for non-paired trades during the trading hours set out in Article 5, paragraph 1.
    Transaction information on non-paired trades will be announced in real time through a system for the posting of trading information.
Chapter III Paired Trades
Article 10     The trading periods for paired trades on the TPEx are 8 a.m. to 8:30 a.m. and 9:00 a.m. to 5 p.m.
    A quote for a paired trade is valid during both trading periods on a given day. Prior to execution, an already placed buy/sell quote for a given paired trade may be canceled during either of the trading periods.
Article 11     (Deleted)
Article 12     Submission of quotes for paired trades is temporarily suspended on all trading days on which no price fluctuation limit is imposed under Article 55, paragraph 4 of the TPEx Trading Rules.
Article 13     The total dollar amount of the buy and sell quotes for paired trades placed by a securities firm on a given day shall be subject to the provisions of Article 35, paragraphs 8 to 10 of the TPEx Trading Rules. If, however, the post-netting dollar amount of the trades of a given pair executed through orders placed by a given securities firm on a given day is zero, the amounts of those trades shall be excluded from the calculation of the aforementioned total dollar amount of the buy and sell quotes.
    (Paragraph 2 deleted)
    (Paragraph 3 deleted)
Article 14     When a securities broker is engaged to submit a buy/sell quote for a paired trade, except where advance collection of funds or securities is otherwise required, the broker may decide at its discretion according to the circumstances whether or not to pre-collect from the principal an appropriate portion or a fixed percentage of such funds or securities.
Article 15     When a securities firm places a buy or sell quote for a paired trade, it shall do so in accordance with the following provisions, and the TPEx shall not match and execute the order until it verifies that the ticker code, unit price, and volume of the security indicated in both of the buy and sell quotes for the paired trade are consistent:
  1. When a single securities firm places both the buy and sell quotes for the same paired trade, it shall first submit a quote indicating the group code, securities firm code, ticker code and unit price of the security, type of quote (buy or sell), and total buy and sell size, and subsequently submit an order ticket indicating the serial number and type of the order ticket, account number of the principal (or dealer), and order volume.
  2. When different securities firms place the buy or sell quotes for the same paired trade, one of the sell-side securities firms shall act as representative and submit a quote indicating the group code, code of each securities firm of both the buy and sell sides, ticker code and unit price of the security, type of quote (purchase or sale), and buy and sell sizes. Subsequently, the sell-side representative securities firm and each of the other securities firms participating in the paired trade shall separately submit an order ticket indicating the serial number and type of the order ticket, account number of the principal (or dealer), and order volume.
    For a paired block trade of a basket of stocks, only one principal's (or dealer's) account number may be submitted for each of the buy and sell quotes, and the TPEx shall not match and execute the order until it verifies that the ticker code, unit price, and volume of each security indicated in both of the buy and sell quotes for the paired trade are consistent.
Article 16     Transaction information on paired trades will be announced in real time through a system for the posting of trading information, but transaction information during pre-opening hours will be announced immediately after market opening.
