  1. Normal settlement.
  2. Trade date settlement.
  3. Designated date settlement.
    The settlement of normal settlement trades shall take place 2 business days after the trade date.
    The settlement of trade date settlement trades shall be effected by written agreement of both parties, and settlement shall take place on the trade date.
    The rules regarding the settlement of designated date settlement trades shall be prescribed by the TWSE and reported to and approved by the Competent Authority before implementation.
57-1    The performance of obligations relating to call (put) warrants shall be handled through securities firms that have executed a market usage contract with the TWSE; provided that where the holder or the issuer has entered into the market usage contract with the TWSE, they may process matters on their own.
    Upon receiving a commission referred to in the preceding paragraph, or when requesting performance of obligation on its own behalf, a securities firm shall confirm the related details of the performance of obligation on the next business day, and complete the transfer of the money/certificate before 10 a.m. of the second next business day.

58    The validity of trading orders relating to the automated computer trading system shall be limited to the day on which the order is placed.
    Unless otherwise provided, trading orders for the automated computer trading system may be keyed-in 30 minutes prior to the opening of the market trading by the participating securities brokers or dealers. Such orders shall include the code of the securities firm, serial number of the brokerage order ticket (or serial number of the proprietary trading order), type of order ticket (margin purchase, short sale, securities lending, central depositary, self-custody), account number of the principal (or of the dealer), code of the securities, type of trade (normal, block, odd-lot), price (limit order or market order), volume, sale/purchase, and period of validity (valid on the current day, canceled if not immediately satisfied, or canceled if not all order is immediately satisfied).

In addition, the TWSE shall disclose, on a real-time basis during trading hours, the executed trade prices and volumes, and the prices and volumes of the five highest unexecuted buy orders and five lowest unexecuted sell orders. As to the prices and volumes of other trading orders, however, the TWSE may make appropriate disclosures based on market needs.
    Application of securities firms for changes to the trading orders that are valid on the current day, except in the following circumstances, shall be accomplished by first canceling the original trading order, and then placing new trading orders.
  1. Reduction of the volume in the order; or
  2. Change of the price of a limit order, in which case the time of the order shall be the time of entry of the updated order, unless otherwise provided by the TWSE.

58-2    In principle, the priority for satisfying trading orders are based on price priority and time priority, and the priority for satisfying trading orders shall be based on the following principles:
  1. Price priority principle: higher-priced buy orders shall have priority over lower-priced buy orders. Lower-priced sell orders shall have priority over higher-priced sell orders. Where orders are placed at the same price, priority shall be based on time priority principle.
  2. Time priority principle: For orders placed prior to the opening of the market, priority shall be determined randomly based on computer arrangement. For orders placed after the opening of the market, priority shall be made on the order in which the orders were placed.
58-3    The competitive auction for trading orders shall be divided into call auction and continuous trading. The first matching in the current session shall be done by call auction, and subsequent matching shall be done by continuous trading until a period of time before market closing, during which all the trading quotes shall be accumulated and matched by call auction.
    Trade prices of call auction shall be determined based on the following principles:
  1. Satisfying the maximum trade volume such that buy orders with prices higher than the determined price and sell orders with prices lower than the determined price shall be all satisfied.
  2. Where there are buy and sell orders with prices equal to the determined price, at least one side shall be all satisfied.

    Trade prices of continuous trading shall be determined by each buy order or sell order that is entered based on the following principles:
  1. When the price of a buy order entered is higher than or equal to the minimum price of a sell order previously entered, orders shall be satisfied from the lowest to the highest price of sell order, in that order, until orders are all satisfied or until the price of the buy order currently entered is lower than the price of the unsatisfied sell order.
  2. When the price of a sell order entered is lower than or equal to the maximum price of a buy order previously entered, orders shall be satisfied from the highest to the lowest price of buy order, in that order, until orders are all satisfied or until the price of the sell order currently entered is higher than the price of the unsatisfied buy order.
    The aforesaid auction reference price at market opening of the current trading session shall be determined by the following principles:

    2. If, on the preceding day, the lowest sell order price at the close of market was lower than the auction reference price at the opening of market, use the lowest sell order price.
    3. When neither of the above circumstances applies, use the auction reference price at the opening of market of the preceding business day.

Trading orders entered prior to market opening that are unexecuted shall continue to be matched in the order as originally randomly assigned by the computer. The closing price shall be the price of trades matched upon accumulation of all trading orders over a period of time prior to market closing. Where unexecuted, the closing price shall be the last traded price during the current session.
    Except securities that are newly listed common stocks during the period when no price fluctuation limit is imposed, and securities for which the opening auction reference price is lower than NT$1, during the period from the first matched trade of a security during the current session until the period of time prior to market closing, if any execution price as test-calculated prior to each matching fluctuates beyond 3.5% of the reference price:
  1. If a trading order entered is a limit order and is valid for the current day, except that an order whose execution price as test-calculated is within the price range and shall be satisfied immediately, the TWSE shall at the same time postpone the matching of the security for two minutes, and continue to accept entries, cancellations, and changes of trading orders for that security.

In the absence of a most recent trade price, however, the opening auction price shall be the reference price.
  3. After the first matching for the current session, in the event of a postponement of matching of a security in the first subparagraph, within the five minutes after the conclusion of the postponement period, the trade price of the call auction during the session is the reference price.

    The opening price of a security is the price of the first matched trade for the current session. Trading orders entered prior to market opening that are unexecuted shall continue to be matched in the order as originally randomly assigned by the computer.

Where unexecuted, the closing price shall be the last traded price during the current session.
    Except securities that are newly listed common stocks during the period when no price fluctuation limit is imposed, and securities for which the opening auction reference price is lower than NT$1, during the period from the first matched trade of a security during the current session until the period of time prior to market closing, if any execution price as test-calculated prior to each matching fluctuates beyond 3.5% of the reference price:

  2. After the first five minutes of the first matching for the current session, prior to each matching, a weighted average price is calculated based on the price and volume of all trades for the five-minute period immediately before the entry time of the order. In the absence of a trade price in the five minutes, the most recent trade price shall be used. In the absence of a most recent trade price, however, the opening auction price shall be the reference price.
  3. After the first matching for the current session, in the event of a postponement of matching of a security in the first subparagraph, within the five minutes after the conclusion of the postponement period, the trade price of the call auction during the session is the reference price. In the absence of a trade price during the session, however, the reference price shall be calculated in accordance with the preceding subparagraph.
    If, during the 1 minute prior to market opening or market close for a security, any given computed execution price fluctuates beyond 3.5 percent from the previous computed execution price (if there is no previous computed execution price available 30 minutes before market opening, the fluctuation shall be based on the auction reference price at market opening; if there is no previous calculated execution price available a period of time before market closing, the fluctuation shall be based on the most recent trade price; if there is no most recent trade price available, the fluctuation shall be based on the auction reference price at market opening), the first matched trade for the current session, or the matching at market close, for that security is postponed. For a security for which the first matched trade for the current session is postponed, matching and execution for the security will proceed sequentially after 2 minutes of postponement. For a security for which the matching at market close is postponed, entries, cancellations, and changes of trading orders for that security will continue to be accepted from 1:31 p.m. to 1:33 p.m., and matching and execution will then proceed sequentially at 1:33 p.m. However, this restriction shall not apply to securities for which the opening auction reference price is lower than NT$1, call (put) warrants, or company warrants.

58-4    The TWSE shall stop accepting orders and trades one business day prior to the expiration of the call (put) warrant.
58-5    After the cause of halting of trading of listed securities ceases to exist, trading may be resumed for ordinary trading and for other trading such as odd-lot, after-market fixed-price, block, auction, and ordinary reverse auction trades. But if the cause of the halting of trading ceases to exist during a certain period of time prior to, or after the close of, market trading hours, trading will not in any event be resumed on that day.
58-6    The time of commencement of a halt of trading or resumption of trading of listed securities shall be determined by the time of execution by the TWSE computer.
    During a period of halted trading of listed securities, the TWSE will cease accepting trading orders. However, for any trading order that is unexecuted prior to the halt of trading, the securities firm may apply to cancel or reduce the quantity of the order.
    When the trading of listed securities is resumed during the period from 30 minutes prior to the commencement of market trading hours to a certain period of time prior to the close of market trading hours, the first matching of the securities will be done by call auction a period of time after the resumption of acceptance of trading orders.
Info
58-7    The "period of time" in Article 58-3 and the preceding two articles shall be prescribed by the TWSE and publicly announced for implementation after approval and recordation by the Competent Authority.
Info
58-8    A trading order can either be a limit order or market order:
  1. A limit order is an order for which a principal has set a certain price where the order is satisfied at or below the price in the case of a buy order, or at or above the price in the case of a sell order.
  2. When giving a market order, a principal does not set a certain price and this order may be satisfied within the permitted price range of the security on the day. However, newly listed common stocks during the period when no price fluctuation limit is imposed, securities subject to no fluctuation limit, securities for which extended matching intervals have been implemented under the bylaws or rules of the TWSE, or those otherwise identified by the TWSE shall not be traded as market order.
    Prior to matching a trade, a market order shall have its reference price converted based on the following principles, with the converted price as its order price:
  1. For a buy order, the converted reference price shall be the most recent trade price of the security (or opening auction reference price in the absence of a most recent trade price), maximum limit buy order, or maximum limit sell order, whichever is higher. If the converted reference price is the same as the maximum limit buy order, it shall be matched before a limit order where price priority under Article 58-2 applies.
  2. For a sell order, the converted reference price shall be the most recent trade price of the security (or opening auction reference price in the absence of a most recent trade price), minimum limit buy order, or minimum limit sell order, whichever is lower. If the converted reference price is the same as the minimum limit sell order, it shall be matched before a limit order where price priority under Article 58-2 applies.
    In terms of period of validity of a trading order, the order is either valid on the current day, canceled if not immediately satisfied in one trade, or canceled if not all trade is immediately satisfied in one trade:
  1. "Valid on the current day" describes an order that is valid during the current session if not all order is satisfied in one trade and the remaining unsatisfied volume is not withdrawn.
  2. "Canceled if not immediately satisfied in one trade" describes that when a trading order is entered, if not all order is satisfied in one trade, the remaining unsatisfied volume will be canceled.
  3. "Canceled if not all order is immediately satisfied in one trade" describes that when a trading order is entered, if not all order is satisfied in one trade, all the order shall be canceled.
    A trading order that is a market order, or with period of validity that is canceled if not immediately satisfied in one trade or canceled if not all order is immediately satisfied in one trade may only be entered during the period allowed for continuous trading under Article 58-3. During the period for call auction, the TWSE withdraws trading orders previously entered as market orders that are valid on the current day.
Info
58-9    Securities for which extended matching intervals have been implemented under the bylaws or rules of the TWSE refer to securities which, pursuant to the TWSE Directions for Announcement or Notice of Attention to Trading Information and Dispositions, are subject to disposition or securities under altered trading methods for which periodic call auction is also used.
    The mechanism for disclosing trading information and implementing price stabilization in regard to the securites in the preceding paragraph is as below:
  1. During the period of trading quotes, the TWSE shall disclose on a real-time basis computed execution prices and volumes, and the computed prices and volumes of the five highest unexecuted buy quotes and five lowest unexecuted sell quotes. In addition, the TWSE shall disclose, on a real-time basis during trading hours, executed trade prices and volumes, and the prices and volumes of the five highest unexecuted buy quotes and five lowest unexecuted sell quotes.
  2. During the period from after the first matching of the current trading session until a certain period of time prior to market close, when the upward or downward movement of any trade price during price calculation prior to matching of each trade exceeds 3.5 percent of the previous trade price, the TWSE will immediately postpone matching of the security for a certain perod and continue to accept entries, cancellations, and changes of buy and sell quotes, and after the end of postponement of trade matching proceed with matching and execution for the security sequentially.
  3. The market stabilization mechanism of the one minute prior to market opening or market close is governed by Article 58-3, paragraph 8 mutatis mutandis.
59    When determining the daily price fluctuation limits for competitive auction trading of an initial listing of securities, unless otherwise provided by law, reference price shall be made to the public offering price before the listing date. Where the securities in the initial listing are already traded on the Taipei Exchange, reference shall be made to the closing price on the last trading day before the cessation of its Taipei Exchange trading.Competitive auction trading of the common stocks of a TIB listed company or a TIB primary listed company that is relisted as TWSE listed company or TWSE primary listed company, as applicable, shall refer to the auction reference price at market opening of the current session on the first day of relisting as the basis of price fluctuation limits.
    When a company limited by shares or a foreign company converts its shares to another newly established company or another already TWSE listed or TWSE primary listed existing company under Chapter IV-1, the daily price fluctuation limits for an initial listing of common shares of such newly established company shall be calculated on the basis of the following reference price: the price arrived at by multiplying (the closing price on the last trading day of the common shares of the TWSE or Taipei Exchange listed company or TWSE or Taipei Exchange primary listed company whose converted common shares are anticipated to account for the greatest proportion of the anticipated issued common shares of the newly established company) by (the number of shares required for exchange of one new share);the daily price fluctuation limits for securities other than common shares of the newly established company or the already TWSE listed or TWSE primary listed existing company shall be calculated on the basis of the following reference price: the price arrived at by multiplying (the closing price on the last trading day of the TWSE listed security or Taipei Exchange listed security anticipated to account for the highest proportion of those converted into the security) by (the number of shares [or trading units] required for exchange of one share [or one trading unit] of the new security).
    Where there is no closing price for the last trading day of any TWSE listed security used for the calculation of a reference price under the preceding paragraph, the price determined by the principles set out in Article 58-3, paragraph 4, subparagraph 2 herein shall be used. Where there is no closing price for the last trading day of the Taipei Exchange listed security used for the calculation of reference price referred to in paragraph 1 or 2, the basis price for the opening of trading on the next day, determined in accordance with the provisions of the GreTai Securities Market Rules Governing Securities Trading on the Taipei Exchange, shall be used.
    The daily price fluctuation limits on initial listings of new capital stock, certificates evidencing right to subscribe to new shares, and certificate evidencing payment shall be determined with reference to the closing price of the old shares on the previous business day minus the value difference on rights; provided where the difference on rights cannot be determined, the price fluctuation limit shall be determined with reference to the closing price of the old shares on the previous business day. Where there is no closing price for the old shares on the previous business day, the price determined by the principles set out in Article 58-3, paragraph 4, subparagraph 2 herein shall be used.
Info
59-1    Where trading of the TWSE listed securities of a TWSE listed company has been suspended or halted, unless otherwise provided, the price fluctuation limit of such securities on the first day of resumption of the suspended or halted trading shall be calculated based on the closing price of the last trading day. If there is no closing price for the last trading day, it shall be replaced by the price determined by the principles set out in Article 58-3, paragraph 4, subparagraph 2 herein.
Info
60    The trading orders shall be given in a single trading unit or multiples thereof. The trading unit of stocks shall be 1,000 shares. The trading unit of government bonds and corporate bonds shall be bonds with par value of 100,000 dollars.
    Where a portion of the principal of government bonds and corporate bonds has been paid, the trading unit shall be calculated based on its remaining principal.
61    The price of trading orders for stocks shall be based on one share of stock. The price of trading orders for government bonds and corporate bonds shall be based on bonds with a par value of 100 dollars.
    The trading of bonds shall be interest-free trades, except where the trading order specifies interest or the regulations specifies otherwise.
    The calculation of the interest specified in the preceding paragraph shall be based on the actual number of days between the interest-bearing commencement date and the trade date.
62    The fluctuation unit (tick) of the prices of trading orders shall be determined as follows:
  1. Where the market price of a stock is less than 10 dollars per share, the tick shall be 1 cent, or 5 cents if the price is from 10 dollars to less than 50 dollars, or 10 cents if the price is from 50 dollars to less than 100 dollars, or 50 cents if the price is from 100 dollars to less than 500 dollars, or 1 dollar if the price is from 500 dollars to less than 100 dollars, or 5 dollars if the price is 1,000 dollars or more.
  2. The tick for government bonds and corporate bonds shall be five cents. The tick for convertible bonds shall be 5 cents if the price is less than 150 dollars, or 1 dollar if the price is from 150 dollars to less than 1,000 dollars, or 5 dollars if the price is 1,000 dollars or more.
63    The daily price fluctuation limits of securities, unless otherwise approved by the Competent Authority, shall be 10 percent above and below the auction reference price at market opening of the current trading session for stocks, and 5 percent above and below the auction reference price at market opening of the current trading session for bonds; provided, however, that if the price fluctuation limit is less than the minimum tick size, the minimum tick size shall be the price fluctuation limit, and the price may not fall lower than the minimum tick size.
    For newly TWSE listed common stocks other than those converted from Taipei Exchange listed stocks to TWSE listed stocks, there will be no price fluctuation limit imposed for the 5 trading days beginning from the listing date, and the minimum price shall be one cent.
     Paragraph 1 shall apply mutatis mutandis to price fluctuation limits for trading of the common stocks of a TIB listed company or a TIB primary listed company that are relisted as TWSE common stocks.

67    In the trading of stocks, where a TWSE listed company has set a date for suspension of changes to the shareholders register (i.e. a book closure date) based on the record date for distributing dividends, bonuses or other interests pursuant to paragraph 2 of Article 165 of the Company Act, all settlements conducted after the book closure date shall be ex-dividend and ex-rights; provided that the provisions of this Article shall not apply to a capital increase out of employee compensation.
    The daily price fluctuation limit after the distribution of dividends shall be based on the closing price of the previous day minus the amount of dividends and bonuses that have been distributed.
    The daily price fluctuation limit for the ex-rights date shall be calculated based on the following:
  1. Where a TWSE listed company uses retained earnings or capital surplus to increase capitalization, the calculation of daily price fluctuation limit for the ex-rights date shall be based on the closing price of the previous day minus the value of the distributed stock dividends.
  2. Where a TWSE listed company uses cash capital to issue new stocks, the calculation of daily price fluctuation limit for the ex-rights date shall be handled by one of the following methods:
    1. In case under cash capitalization the issue price of the newly issued stock is lower than the closing price on the day immediately preceding the ex-rights date, the daily price fluctuation limit for the ex-rights date shall be the closing price on the day immediately preceding the ex-rights date for the purpose of determining the maximum high, and the closing price on the day immediately preceding the ex-rights date minus the value of the newly issued cash capitalization stock for the purpose of calculating the maximum low.
    2. In case under cash capitalization the issue price of the newly issued stock is higher than the closing price on the day preceding the ex-rights date, the daily price fluctuation limit on the ex-rights date shall be the closing price on the day immediately preceding the ex-rights date minus the value of the newly issued cash capitalization stock for the purpose of determining the maximum high, and the closing price on the day immediately preceding the ex-rights date for the purpose of calculating the maximum low.
  3. Where a TWSE listed company simultaneously uses retained earnings or capital surplus to increase capitalization, and also uses cash capital to issue new stocks, the daily price fluctuation limit shall be calculated as follows:
    1.
