   For a Leveraged or Inverse ETF of which the component securities of the underlying index are all domestic securities/ Leveraged or Inverse ETN of which the component securities of the underlying index are all domestic securities	The relevant daily price fluctuation limit for the beneficial certificates is 10 percent multiplied by the multiple of the fund.
   Warrants	Limits on call (put) warrants for which the underlying is a domestic single stock or an exchange-traded securities investment trust fund announced by the TWSE shall be calculated as follows: For call warrants Limit-up price = Auction reference price at market opening for the given day + (Limit-up price of the underlying security for the given day –Auction reference price at market opening for the underlying security for the given day) × Exercise ratio Limit-down price = Auction reference price at market opening for the given day - (Auction reference price at market opening for the underlying security for the given day - Limit-down price of the underlying security for the given day) × Exercise ratio For put warrants Limit-up price = Auction reference price at market opening for the given day + (Auction reference price at market opening for the underlying security for the given day – Limit-down price of the underlying security for the given day) × Exercise ratio Limit-down price = Auction reference price at market opening for the given day – (Limit-up price of the underlying security for the given day – Auction reference price at market opening for the underlying security for the given day) × Exercise ratio Fluctuation limits on call (put) basket warrants shall be calculated for each underlying security within the basket using the following formulas: (1) (Limit-up price of each underlying security in the basket for the given day –Auction reference price at market opening for each underlying security for the given day) × Sum of exercise ratios for each underlying security in the basket; and (2) (Auction reference price at market opening for each underlying security for the given day – Limit-down price of each underlying security for the given day) × Sum of the exercise ratios for each underlying security in the basket. The larger of these two figures shall be plugged into the formulas in the preceding sub-paragraph to calculate the daily fluctuation limits. Limits on index call (put) warrants for which the underlying is an index as announced by the TWSE shall be calculated using one of the following two formulas: Limit-up price for call (put) warrants = Auction reference price at market opening for the given day ＋ (Closing index of the underlying index on the previous day × corresponding monetary value per index point × Exercise ratio × 10%). Limit-down price for call (put) warrants ＝Auction reference price at market opening for the given day － (Closing index of the underlying index on the previous day × corresponding monetary value per index point × Exercise ratio × 10%). No price fluctuation limit is imposed on call (put) warrants for which the underlying is an exchange-traded fund with foreign component securities, or an offshore exchange-traded fund, or a foreign security, or a foreign index.
   Preferred Shares with Warrants	Limit-up price = Auction reference price at market opening for the given day *(1+10%) + (Limit-up price of the underlying security for the given day –Auction reference price at market opening for the underlying security for the given day) × Exercise ratio Limit-down price = Auction reference price at market opening for the given day *(1-10%)- (Auction reference price at market opening for the underlying security for the given day - Limit-down price of the underlying security for the given day) × Exercise ratio
   Corporate Bonds with Warrants	Limit-up price = Auction reference price at market opening for the given day *(1+5%) + (Limit-up price of the underlying security for the given day –Auction reference price at market opening for the underlying security for the given day) × Exercise ratio Limit-down price = Auction reference price at market opening for the given day *(1-5%)- (Auction reference price at market opening for the underlying security for the given day - Limit-down price of the underlying security for the given day) × Exercise ratio
   Company Warrants	Limit-up price = Auction reference price at market opening for the given day + (Limit-up price of the underlying security for the given day –Auction reference price at market opening for the underlying security for the given day) × Exercise ratio Limit-down price = Auction reference price at market opening for the given day - (Auction reference price at market opening for the underlying security for the given day - Limit-down price of the underlying security for the given day) × Exercise ratio

5. Orders types:

   New order types such as market order, Immediate or Cancel (IOC), and Fill or Kill (FOK) are available only during the continuous trading sessions. These provide investors with more options when placing orders.

   1. Market orders
      When placing a market order, the investor does not need to specify a certain price, and the order may be settled within the price fluctuation range of the securities of the day.
      1. How to place a market order
         1. Market orders will only be accepted during the continuous trading session, and will not be accepted at the call auction session (opening, closing or when intraday volatility interruption is triggered). When the intraday volatility interruption takes place or during the closing session, all market orders remaining in the order book will be automatically deleted by the TWSE and securities firms will be notified of the deletion.
         2. When placing a market order, the investor does not need to specify a certain price.
         3. Restrictions on market orders:
            1. For securities which are restricted to place at a price lower than the closing price of the previous business day, these are not available for short selling with market orders.
            2. For securities in the first five days of their IPO and those not subject to price fluctuation limits, market orders will not be accepted: The reason is the securities in these two categories are not subject to any price fluctuation limits. For these securities, transactions could take place at any price. In order for the trade price to reach beyond investors’ expectations, there are regulations in place that exclude market orders from trading of these securities.
            3. Securities that the TWSE has listed as disposition securities or listed under the altered-trading-method category: These securities are to be traded by call auction and market orders are not applicable.
      2. Matching rules for market orders
         1. A market order executes at the best available price. If, after the matching, there are market orders remaining in the order book, they will always be listed as the top priority. Even if there are limit orders that are subject to upper and lower price fluctuation limits in the order book, market orders will still be the top priority.
         2. "Prior to matching a trade" subject to a market order, the "reference price shall be converted" based on the following principles, with the converted price as its order price:
            1. In the case of market buy orders, the converted reference price shall be the most recent trade price of the applicable securities (or auction reference price at market open in the absence of a most recent trade price), the highest buy order price in the order book, or the highest sell order price in the order book, whichever is higher.
            2. In the case of market sell orders, the converted reference price shall be the most recent trade price of the applicable securities (or auction reference price at market open in the absence of a most recent trade price), the lowest buy order price in the order book, or the lowest sell order price in the order book, whichever is lower.

      Example: The most recent trade price is TWD100. In the order book, the volume of market sell order was 3, limit sell order at TWD99 was 1, and limit sell order at TWD100 was 1.
      Now there is a new market buy order of volume 3.

      

          Based on the matching principle for continuous trading, transactions are taking place at the price offered by the counterparty in an appropriate order:
      In this example, the market orders remaining in the order book are sold at the converted reference price of TWD99 and the volume of 3. The market orders executed before the limit orders despite that the limit sell orders are offered at the same price of TWD99.
      

      

   2. Immediate or cancel (IOC) order

          An immediate or cancel (IOC) order is an order to buy or sell a security that executes all or part immediately and cancels any unfilled portion of the order. For example, if the volume of an IOC order is 10, and only 5 are available , these 5 will be traded and the other 5 will be automatically cancelled.

      1. An IOC order will be accepted only during the continuous trading session, and this type of order will not remain in the order book. No IOC order will be accepted at opening, closing or when intraday volatility interruption is triggered.
      2. When order prices are being taken into account, an IOC order can be a limit IOC order or a market IOC order.

      Example
      

      

   3. Fill or kill (FOK) order

          A fill or kill (FOK) order is an order for which a transaction is executed immediately and completely or not at all. For example, if the volume of an FOK order is 10, and only 5 are available, all 10 will be cancelled and not traded.

      1. An FOK order may only be accepted during the continuous trading session, and the order will not remain in the order book. No FOK order will be accepted at opening, closing or when intraday volatility interruption is triggered.
      2. When order prices are being taken into account, an FOK order can be a limited FOK order or a market FOK order.

      Example
      

      

   Incorporating the current limit order and Rest of Day (ROD) with the new orders types mentioned above, there are six new order types listed as below.

   	Price	Duration	New	Applicable session
   1	Limit order	ROD		Opening and closing session, continuous trading session, during intra-day volatility interruption
   2	Limit order	IOC	NEW	Continuous trading session
   3	Limit order	FOK	NEW	Continuous trading session
   4	Market order	ROD	NEW	Continuous trading session
   5	Market order	IOC	NEW	Continuous trading session
   6	Market order	FOK	NEW	Continuous trading session

6. Addition of the order price change feature:

   In the current system, an investor who wants to change the order price has to cancel the order and place a new one. After continuous trading is online, a new order feature is added to allow an investor to directly change the order price to reduce the amount of information. Please note, however, when an order price is changed, the order time shall become the time when the price was changed.

   Example: Investor A placed an ROD bid volume one of Share X for a price of TWD100 at 9:01 am. Price of Share A continued to go up. At 9:30 am, Investor A decided to change the price to TWD105 and he did that using the order price change feature, and the order time was also changed from 9:01 am to 9:30 am.

   → The order price change feature basically combines two actions, "cancel an order" and "place a new order", into one. So the order time should naturally be the time when the new order is placed. In other words, the time of the order price change is the time when the order price is changed.

   • Restriction on use of the order price change:
     For securities which are restricted to place at a price lower than the closing price of the previous business day, their price shall not be changed to be lower than closing price of the previous business when short selling.
7. Matching

   All securities listed on the Exchange are traded through Fully Automated Securities Trading (FAST).Investors can place orders in person, by phone or internet. Orders are entered via terminals on securities firms’ premises into TWSE’s main computer and are processed and executed by the trading system using a price-time priority precedence hierarchy. In special cases, listed stocks may be traded through negotiation, auction, tender offer or other means. All Securities are executed on a continuous basis during intraday regular trading sessions, and are matched by call auction at the opening and closing of the regular trading session.

   Matching methods on regular trading period:

   Period	Matching Methods
   Opening session 8:30 - 9:00 (or first matching after 9:02 in case of postponement of securities market open)	Call auction
   Intraday trading session 9:00 - 13:25	Continuous trading
   Intraday Volatility Interruption	Call auction
   13:25 - 13:30 (or 13:33 in case of postponement of securities market close)	Call auction

   Order Types:Limit order, Market order, Rest of day(ROD), Immediate or Cancel(IOC), and Fill or Kill(FOK) are available during the continuous trading sessions. However, investors could only place Limit ROD during call auction session. In order to limit extreme price fluctuation, intra-day volatility interruption is in place. Whenever the trading system detects that the potential execution price of a specific stock will fall out of a specified range (+/-3.5%) as compared to the weighted average traded price over the preceding five minutes (reference price), matching for that stock is postponed for two minutes. The suspended stock will resume trading with a call auction, then return to continuous trading.
   1. How the measures are implemented:
      1. 9:00-9:05：The basis is the opening price generated by call auction, or auction reference price at market opening in the absence of an opening price for the first matching.
      2. After 9:05：The weighted average price is calculated based on transactions taking place in the five minutes before an order (only trade prices of continuous trading are being considered, not the opening price generated by call auction). If there is no trade price during the five minutes, the basis is the most recent trade price, or auction reference price at market opening in the absence of a recent trade price.
      3. Volatility Interruption measures：For individual stocks, starting the first matching after 9:00 am, if the intraday volatility interruption measures are triggered, during the first five minutes after the intraday volatility interruption, the basis shall be the trade price of the call auction, or the most recent trade price in the absence of trade price of the call auction, for that intraday volatility interruption session. After the five minutes, calculation of rolling weight average prices will resume.

      Example: The stock has an opening price of TWD100 at 9:00 am. At 9:01 am, has a trade price at TWD100 of volume 1; at 9:02 am, has a trade price at TWD101 of volume 4; at 9:03 am, has a trade price at TWD102 of volume 5. If the potential trade price at 9:05:01 am is TWD105:

      • Because 9:05:01 am is past the five minutes after the first matching, the reference price is the "weighted average price for the first five minutes". The reference price is the weighted average price, taking into account all trade prices and number of transacted volume between 9:00.01 am ~9:05:01 am, which is TWD101.4 (TWD100*1+ TWD101*4 + TWD102*5) ÷ (1 + 4 + 5). Compared with the price, the potential trade price TWD105 exceeds by 3.5%, which triggers intraday volatility interruption when matching is suspended until 9:07:01 am. At 9:07:01 am, orders are matched by call auction. After that, continuous trading resumes.
      • At 9:07:01 am, if based on the result of call auction matching the trade price is TWD104, the reference price for the next five minutes (until 9:12:01 am) will be TWD104. After 9:12:01 am, calculation of the 5-minute weighted average price resumes.
   2. Intraday Volatility Interruption for various types of orders

      Investors can add limit ROD orders during intra-day volatility interruption. However, market order, IOC, and FOK are not accepted. After continuous trading, types of orders increase and each order may have multiple trade prices. With the characteristics of orders being considered, only limit rest of day (ROD) orders may trigger intraday volatility interruption. For all other orders, if prices exceed the range, it could partially be traded within the range, and partially be automatically canceled because of a price exceeding the range.

   When the intra-day volatility interruption is triggered, the matching system will automatically delete existing market orders. During the intra-day volatility, trading information will be disclosed every five seconds, same as the opening and closing session.
   
   

   Limit ROD order - Example
   If the reference price is TWD100 and the maximum and minimum prices that trigger intraday volatility interruption are TWD103.5 and TWD96.5, and the new ROD bid is at TWD105 with volume 10:

   

   After intraday volatility interruption is triggered, matching is postponed for two minutes and then the trade is matched by call auction.
   (What an order book looks like when intraday volatility interruption are triggered)

   

   
   

   Market ROD order - Example
   If the reference price is TWD100 and the maximum and minimum prices that trigger intraday volatility interruption are TWD103.5 and TWD96.5, and the new ROD market order would like to bid with volume 10:

   

   Intraday volatility interruption will not be triggered. The remaining market orders will automatically be canceled.
   (What an order book looks like after the transaction.)

   

   
   

   IOC order - Example
   If the reference price is TWD100 and the maximum and minimum prices that trigger intraday volatility interruption are TWD103.5 and TWD96.5, and the new IOC bid is at TWD105 of volume 10:

   

   Intraday volatility interruption will not be triggered. The remaining IOC orders will automatically be canceled.
   (What an order book looks like after the transaction.)

   

   
   

   FOK order - Example
   If the reference price is TWD100 and the maximum and minimum prices that trigger intraday volatility interruption are TWD103.5 and TWD96.5, and the new FOK bid is at TWD105 of volume 5:

   

   Intraday volatility interruption will not be triggered. The FOK order will automatically be canceled.
   (What the order book looks like.)

   

   
   Exceptions to circumstances when intraday volatility interruption is not triggered
   1. First matching after 9:00 am.
   2. Securities with the auction reference price at market open lower than TWD1: For these securities, when their price goes up or down for one or two tick sizes, the price fluctuation exceeds 3.5%. To avoid frequent triggering of intraday volatility interruption that would reduce matching efficiency, the intraday volatility interruption does not apply to these securities.
   3. Call (put) warrants: Because of the characteristics of these commodities, their daily price fluctuation limits are calculated based on the maximum price fluctuation of their underlying securities and may be at multiples of price fluctuation limits. Given the characteristics in the trading of these commodities, the intraday volatility interruption is not applicable.
   4. For IPO securities in the first five trading days when they are not subject to daily price fluctuation limits: In order to allow IPO common shares to have a price that fully reflects their reasonable value and to meet the market demand, IPO common shares, not including OTC shares that become listed at the exchange or other securities that are not common shares, in the first five trading days after the IPO, there are no daily price fluctuation limits and therefore these intraday volatility interruptions will not be triggered during this period of time.
8. Real-time trading information disclosure

   Trading price, volume, best 5 bid/ask price and volume are disclosed on a “real time” basis, and a “5-second snapshot” is also provided. This allows market participants to make an informed judgment when placing orders. This information can be accessed at:

   https://mis.twse.com.tw/stock/index.jsp?lang=en_us
9. Information Disclosure before Market Opening and Closing Summary

   Taiwan Stock Exchange (hereinafter TWSE) and Taipei Exchange (hereinafter TPEX) will disclose simulated transaction prices, simulated trading volumes, simulated best five bid/ask prices, and simulated bid/ask volumes for investors’ reference in making orders before market opening (08:30-09:00) and during the last five minutes before market closing (13:25-13:30).

   If in the last 1 minute before market opening (08:59-09:00) or closing(13:29-13:30), there is a volatile change of a securities reference price that reaches a specific rate simulated by the order-matching system, market opening will be temporarily suspended 2 minutes for those individual stocks.

   During suspension, investors’ new limit ROD orders, cancellations and revision requests will continue to be accepted and information of simulated transaction prices, simulated trading volumes, and simulated best five reported bid/ask prices and volumes will continually be disclosed to provide investors with an opportunity to consider adding, cancelling or altering an order of a stock with high price volatility before market opening.

2. Warrant Trading

1. Matching
   Orders for warrants are executed either through call auction or through continuous trading.
2. Applicable Time
   1. Orders are executed on a continuous basis during intraday regular trading sessions.
   2. Orders are still matched by call auction at the opening and closing of the regular trading session.
   3. Warrants are subject to trading by call auction as a result of dispositional measures or full cash settlement requirement during regular trading sessions, following the prescribed cycle time frame (e.g. every 5, 10, or 30 minutes).
3. Principles of Continuous Trading
   1. Principles for Determining Execution Prices
      

      In continuous trading, buy and sell orders are executed on an order-by-order basis. The execution price is determined according to the following principles:

      1. If a bid quote is placed at a price higher than or equal to the lowest price of unexecuted ask quotes, the bid quote will be executed against one or more of these ask quotes, in ascending order of ask price, until the bid quote is completely satisfied, or until the price of the bid quote is lower than the price of unexecuted ask quotes.
         Please see Figure 1.1 for an illustrative example.
         Figure 1.1

         

         
         
      2. If an ask quote is placed at a price lower than or equal to the highest price of unexecuted bid quotes, the ask quote will be executed against one or more of these bid quotes, in descending order of bid price, until the ask quote is completely satisfied, or until price of the ask quote is higher than the prices of unexecuted bid quotes. Please see Figure 1.2 for an illustrative example.
         Figure 1.2

         

         
         
   2. Principles for order execution priority
      Orders is matched and executed sequentially based on the principles of price priority and time priority.
      1. Principle of price priority: Bid quotes with higher prices take precedence over those with lower prices, and ask quotes with lower prices take precedence over those with higher prices. If two or more quotes are placed at the same price, order execution will be determined according to the principle of time priority.
      2. Principle of time priority: Quotes placed before market opening take precedence over those placed after market opening. Quotes placed before market opening are sequenced randomly by computer, while those placed after market opening is determined by time they are placed.
         
4. Intra-day Volatility Interruption
   To allow the trading prices of warrants to move in line with the prices of underlyings, no intra-day volatility interruption will be taken for warrants.
5. Disclosure of information on the prices and volumes of executed and unexecuted bid and ask quotes
   1. The execution prices and volumes are disclosed in real time when orders are matched. A further disclosure is made after the final matching, indicating the prices and volumes of the five highest unexecuted bid quotes and five lowest unexecuted ask quotes.
   2. Take an example from the matching status given in Figure 1.1. After the buy order is executed, three separate, real-time disclosures are made on the execution prices and volumes, namely NT$103.00/10 lots for the first matching, NT$103.50/20 lots for the second matching, and NT$104.00/20 lots for the third matching. At the time of the third disclosure, a further disclosure is made simultaneously, disclosing the prices and volumes of five best unexecuted bid and ask quotes, which in this case are, respectively, NT$102.50/10 lots, NT$102.00/20 lots, NT$101.50/30 lots, and NT$101.00/40 lots for unexecuted bid quotes, and NT$104.00/10 lots, NT$104.50/40 lots, and NT$105.00/50 lots for unexecuted ask quotes. The information disclosure is shown in Figure 1.3. Figure 1.3

      

      
      
   3. Take another example from the matching status given in Figure 1.2. After the sell order is executed, three separate, real-time disclosures are made on the execution prices and volumes, namely NT$103.00/10 lots for the first matching, NT$102.50/20 lots for the second matching, and NT$102.00/20 lots for the third matching. At the time of the third disclosure, a further disclosure is made simultaneously, disclosing the prices and volumes of five best unexecuted bid and ask quotes, which in this case are, respectively, NT$102.00/10 lots, NT$101.50/40 lots, NT$101.00/50 lots for unexecuted bid quotes, and NT$103.50/10 lots, NT$104.00/20 lots, NT$104.50/30 lots, NT$105.00/40 lots for unexecuted ask quotes. The disclosure information is shown in Figure 1.4. Figure 1.4

      

      
      
6. The system of continuous trading for warrants was implemented on 28 June 2010.

4.Intraday odd lot trading

1. Background

   To make the Taiwan Stock Exchange more accessible to the public and to better satisfy investors' trading needs, Taiwan Stock Exchange Corporation (“TWSE”) has amended the “Taiwan Stock Exchange Corporation Regulations Governing Odd-lot Trading of Listed Securities” with the approval of the Financial Supervisory Commission (“FSC”). The regulations were released to the securities firms on February 26, 2020. Investors will be able to do intraday odd lot trading starting on October 26, 2020. The existing after-hours odd lot trading system will remain unchanged.

2. Introduction

   Item	Description
   Quote time	9 am to 1:30 pm To keep odd lot trading from interfering with the opening for regular trading, securities firms will start entering quotes into the exchange at 9 am, and the first call auction will be executed at 9:10 am.
   Call auction	The first call auction is executed at 9:10 am, followed by periodic call auctions in 1-minute intervals. Order execution priority: 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 the time priority principle. Time priority principle: For orders placed before the first call auction, priority shall be determined randomly by the computer system. For orders placed after the first call auction, priority shall be determined by the order in which the orders are entered.
   Quote range and fluctuation	Same as regular trading on every business day (9 am to 1:30 pm on the day; limited to 10% above or below the reference price on the day) Given there are no price fluctuation limits for newly listed stocks on the first five days of listing, there will be no price fluctuation limits for odd lot quotes in the same period.
   Order placement	To avoid trade disputes arising from clerical error at securities firms, order placement and confirmation of odd lot trades must be conducted electronically, except where the principal is a professional institutional investor.
   Order type	Day orders only
   Closing and order removal	Outstanding intraday odd lot orders will not be carried forward to the after-hours odd lot session.
   Disclosure	Market data: Following each match after the first call auction, market information including the trading price and volume and the best five bid/ask prices and volumes will be disclosed to the public. Simulated market information during the session: The first disclosure will be executed at 9:00:10 am, followed by simulated matching in 5-second intervals until 1:30 pm. Simulated trading prices and volumes, and the best five bid/ask prices and volumes will be disclosed.
   Intra-day volatility interruption system	In order to prevent trading prices from exceeding investors' expectations as a result of drastic price volatility, except for newly listed securities not yet subject to price fluctuation limits and securities for which the reference price is lower than NT$1, price stabilization measures will be in place for intraday odd lot trading from the first successful match to a certain interval before the quote time ends (1:25 pm). If the potential execution price before matching rises or falls by over 3.5% in comparison with the last trading price, the TWSE will instantly delay the current matching by two minutes and continue to accept key-in, cancellation and changes of buy/sell orders within the delayed matching period, and then match orders sequentially after the current delayed matching period comes to an end. The price stabilization measures delay matching, and disclose to investors simulated matching trading prices and volumes and the best five bid/ask prices and volumes in 10-second intervals.

11.Suspending and Resuming Trading of Securities

For the purposes of reducing information asymmetry and protecting the rights and interests of investors, a trading mechanism for the suspension and resumption of securities is in place within the centralized market of the TWSE. The trading mechanism is subdivided into two types, as summarized below:

A. Suspending and Resuming Trading of TDR

Starting from October 3, 2011, when a special cause exists for a secondary listed company, such as stock price sensitive information pending announcement or the occurrence of a material event, by the securities exchange or securities market on which are listed securities represented by Taiwan Depositary Receipts, of the halting of trading thereof, the TWSE may announce halting of trading of the company's Taiwan Depositary Receipts and the relevant call (put) warrant. Upon an announcement by the securities exchange or securities market on which the securities represented by the Taiwan Depositary Receipts, of the resumption of trading thereof, the TWSE may announce the resumption of trading of the company, provided that the specific instance of halting of trading did not result in any material violation of TWSE rules in connection with material information, necessitating suspension of trading of the Taiwan Depositary Receipts.

B. Suspending and Resuming Trading during Information Assessment Period

Starting from January 15, 2016, where a listed company plans to publicly disclose or convene a board of directors meeting for a material information before 5:00 p.m. on a business day, it shall apply to the TWSE for a trading suspension. The company can apply for trading resumption after a full disclosure or explanation of the relevant information has been made. In addition, if the listed company discovers media reports or other information that may significantly affects shareholders' equity or securities prices, yet is unable to make a complete explanation on the same day, it should also apply to the TWSE for a trading suspension. If the listed company is unable to make a complete explanation and did not apply for a trading suspension on the day of the discovery, TWSE may take the initiative to suspend the securities dealings of the listed company if necessary, and resume the trading after the relevant information is fully disclosed.

Suspending and Resuming Trading of TDR

1. Applicable Securities
   Taiwan Depositary Receipts (TDRs) and call (put) warrants of which the underlying securities are TDRs and foreign securities.
2. Applicable Trading: the following types of trading could be suspended and resumed:
   1. Regular trading.
   2. Applicable Trading: the following types of trading could be suspended and resumed:
   3. Securities borrowing and lending trading: newly borrowed securities and provision of collateral.
3. Time to suspend/resume trading
   1. Trading Suspension
      A trading suspension could be implemented anytime before 5:00 p.m. Given that when a trading suspension is in effect, in addition to regular trading (trading from 8:30 a.m. to 1:30 p.m.), other types of trading are also suspended, the time period that a trading suspension may be implemented would accommodate the trading session for each different type of trading. Among all types of trading, the longest trading session is that for block trading (from 8:00a.m. to 8:30 a.m. and from 9:00 a.m. to 5:00 p.m.). As such, a suspension of trading could be implemented anytime before 5:00 p.m.
      For example, if the trading session is suspended at 9:30 a.m., regular trading and block trading are suspended. If the trading session is suspended at 2:10 p.m., block trading, odd-lot trading and after-market fixed-price trading are suspended.
   2. Trading Resumption
      
      1. The resumption of trading could be implemented by 12:50 p.m. If the trading of the underlying securities is suspended due to pending announcement of sensitive stock price information, the trading could be resumed by 12:50 p.m., when the reason for trading suspension no longer exists due to full announcement of such information.
      2. No trading may be resumed after 12:50 p.m. even if the reason for suspending trading no longer exists. This restriction is mainly to avoid not having sufficient time to accept investors' orders again after regular trading is resumed.
      3. Special management
         If the TDRs are placed in disposition securities or subject to an altered trading method and periodic trading, the first matching following resumption of trading will be done at the matching time originally set. An example of altered trading method and periodic trading: If the trading session is resumed at 9:50 a.m., although 30 minutes after the investors placed orders is 10:20 a.m., as the securities should be matched at the matching time originally set (matching time is every thirty minutes starting from 9:00 a.m., which is 9:30 a.m., 10:00 a.m. 10:30 a.m., etc), the first matching time would actually be 10:30 a.m..
4. Method for Suspending Trading
   
   1. The time of trading suspension shall be as announced by the TWSE.
   2. After trading suspension, no orders may be accepted and all matching shall cease in all of the abovementioned types of trading.
   3. Unexecuted orders placed by a securities firm before suspension of trading are effective on the date they are placed. After the trading suspension, the unexecuted orders may be cancelled or the volume of the unexecuted orders may be reduced, and new orders may not be placed.
5. Method for Resuming Trading
   The time of trading resumption shall be as announced by the TWSE.
   
   1. Regular Trading
      Upon the resumption of trading, the TWSE will first accept orders entered by securities firms. The first matching will be conducted 30 minutes thereafter through call auction. Call (put) warrants will be matched by continuous trading after the call auction.

      

   2. Other Types of Trading and Borrowing of Securities
      Following resumption of trading, orders may be entered by securities firms and matched in accordance with the original rules. For example, block trade is resumed at 11:30 a.m. on the date of the order, the order will be accepted and matched immediately.
6. Auction Reference Price at Market Opening
   The auction reference price at market opening of TDRs and call (put) warrants on the business day after the suspension of trading shall be subject to Paragraph 2, Article 58-3 of the Operating Rules for the TWSE. When trading is suspended during regular trading hours and has not been resumed, if there is no trade price prior to the trading suspension, the auction reference price at market opening on the following business day will be: (1) the highest buy order's price, if on the day when trading is suspended, the highest buy order's price at the close of market was higher than the auction reference price at market opening that day; (2) the lowest sell order's price, if on the day when trading is suspended, the lowest sell order's price at the close of market was lower than the auction reference price at market opening that day; or (3) the auction reference price at market opening of the following business day, if neither (1) nor (2) applies.
