- Fairness related description:
- Co-Location service description:
-
Servers of Co-Location service users and TWSE matching engine and trading information systems are placed in the same location. Both are connected directly to high speed local area network (LAN) passing through a wide area network (WAN). The result is lower latency and improved transmission efficiency for the trading system. Furthermore, all servers of Co-Location service users are connected to the trading system mainframes by identical distance to ensure equal conditions for all users.
-
All securities firms (head office) and Information Vendors who have signed the "Supply and Use of Trading Information Contract" with TWSE to access market data through direct connection are eligible to apply for the service.
-
TWSE provides space in the data center, including power facilities, fire safety equipment, air conditioned environment, racks, lines, and secure access control, for users to store servers and network equipment necessary to establish direct connections to TWSE matching engine and trading information systems:
- Basic package:
- 100Mbps Standard rack (two types of data center environments with a maximum 4KW or 5KW per rack power supply) and one 100Mbps line for trading and one for market data transmission (with one free 100Mbps backup line each to satisfy the need for trading or market data transmission backup before 2021/01/01).
- 1 Gbps Standard rack (two types of data center environments with a maximum 4KW or 5KW per rack power supply) and one 1 Gbps line for trading and one for market data transmission.
- Users are also welcome to apply for non-standard racks.

The package includes a 4KW or 5KW standard rack plus one 100Mbps line for trading on TWSE or TPEx and one for market data transmission (a total of 4 100Mbps lines for the two markets).
- Value-added services: rack relocation, rack reservation, additional trading or market data lines, links between Co-Location racks and user's dedicated lines with telecommunications company, and application for emergency maintenance access.

-
Yes, the minimum period for access to the services is 3 months.
-
All securities firms are eligible to apply for the service through their head offices. Those operating both proprietary trading and brokerage services should ensure fair treatment for investors so that use of the service for the brokerage services shall not be subordinate to that for proprietary transactions, except for proprietary traders performing quoting obligations.
-
- Racks related description:
-
TWSE provides rack reservation as a value-added service for users to make plans for future development. Furthermore, to protect other users, reservation is subject to a maximum period of 6 months starting on the day when TWSE agrees to the reservation.

-
Space reserved for A/C vents does not have to be deducted, but panels and cable managers take up 1U each. The actual space available is 40U.
-
TWSE offers an early bird plan that waives the rack setup fee for the first rack, but starts charging the regular setup fee on the second rack.
-
TWSE will install 78 racks in early phases of the service.
Assuming 78 securities firms apply for Co-Location at the beginning, TWSE, in the interest of fairness, will provide only one rack to each securities firm, and make more available to those interested when all racks in the second phase are installed.
If more than one large securities firm is interested in leasing multiple racks, TWSE will allocate the remaining racks at the time on a pro rata basis.
-
- Trading and market data lines related description:
-
The 100M lines are Cat6 UTP and not optical fiber lines. The regulations require connections to TWSE go through firewalls.
-
TWSE will make best efforts to make additional lines available for lease.
-
The basic package comes with one 100Mbps line for trading and one for market data transmission included in the application. The lines cannot be replaced all by market data lines, and different service charges cannot be provided.
-
At present, a securities firm may apply for only two TMP trade report lines. A user with risk concerns may consider sharing trade settlement files to combine settlement data from two offices. Both offices can receive the same trade report, effectively achieving line and data backup.
-
TWSE follows the existing fee schedule to charge for the market data lines for securities firms provided by the Co-Location service.
-
We have completed the planning and construction, and will launch the services in the future.
-
The upper limited for each securities firm are 100 FIX Sessions currently.

There are rack PDUs in the racks. They are vertical and not horizontal or taking up space. Users are not allowed to use their own PDUs for safety reasons.
-
The rack PDU provides twenty four 5-20R outlets and six L6-20R outlets. Are they for one PDU or two?The data center is equipped with 2N power supply. The numbers above are for one PDU, one on each side of a 4KW rack.

-
While racks can technically be shared, but additional negotiation will be required. The service hours for different markets will be determined by the competent authorities, and the fee schedules will be established by the exchanges.
-
Racks may be shared between TWSE and TPEx. However, a user's line with the TPEx Co-Location service is not restricted to trading on Over-the-counter market (OTC) only, but can be used to trade emerging stocks and bonds. In other words, all transactions involving TPEx in the future will go through the same line. In addition, in the interest of market segregation and security, TWSE has made plans for separate lines to be used for different markets.
-
TWSE provides rack reservation as a value-added service for users to make plans for future development. Furthermore, to protect other users, reservation is subject to a maximum period of 6 months starting on the day when TWSE agrees to the reservation.
