Regarding pre-trade transparency, TDX keeps an order book for all the admitted instruments. The order book includes bid/ask prices, time and volume. The order books can be viewed on the Taurus website www.t-dx.com. The six best bid and ask prices are shown with the corresponding volumes.

Regarding post-trade transparency, all trades executed via TDX will be promptly published on the website www.t-dx.com stating the price, the quantity and the time.

When a transaction is confirmed as “executed” on TDX, it will be conclusive evidence of the relevant two (2) Participants having entered into a valid, legal and binding agreement.

For traditional securities, the delivery and payment of the securities shall be effected in accordance with the market practices and in the case of securities which can be canceled and processed by SIX SIS AG in accordance with their rules.

The supervision of TDX is the responsibility of an independent internal function of Taurus.

Taurus keeps chronological records of all orders and transactions made via the TDX platform.

Taurus uses, where relevant, a market surveillance system to monitor compliance to applicable market conduct rules.

9. Taurus trading book

Taurus may maintain its own trading books, for example to provide liquidity as a market-maker on some market segments.

The Taurus trading team responsible for the Taurus trading books is independent from the Taurus team operating the OTF to ensure that client interests are comprehensively protected when conducting proprietary transactions on the OTF.

If Taurus acts as a market maker, it must disclose in a suitable manner that it uses the OTF to trade against its own book. Furthermore, it must publish details at least once a month, broken down by product category, of the volumes traded via the OTF on its own account. The maximum daily volume of trading on own account must also be published for the previous month by product category.

10. Issuance services

The regulatory requirements allow market making for the purpose of ensuring liquidity in a security on both buy and sell sides and, where appropriate, reducing the bid/ask spread (FINMA Circular 2013/08 Market Conduct Rules, margin no. 32 and FINMA Newsletter no. 52 Trading own equity securities with the purpose of ensuring liquidity under the new provisions on market manipulation).

Issuers whose securities are listed for trading on TDX and who, with the purpose of ensuring liquidity, trade own securities or engage a third party to do so, are allowed to do so as long as they make available liquidity (or tradable volume) that moves with the market trend. In other words, they are not allowed to artificially support their security price or fix their security price against the market trend. For this purpose, an issuer contract is concluded with TDX prior to start such activities. Employees of issuers or third party companies mandated to provide such liquidity must comply with the aforementioned requirements.

11. Liabilities

Taurus assumes no responsibility for the registration of the new shareholder into the shareholders' register of a company.

Taurus is not liable for any damage caused by intent or gross negligence of a Participant, its clients or third parties by acts or omissions. In particular, Taurus is not liable for damages resulting from:

  1. trade interruptions

  2. cancellation of orders due to suspicion of inadmissible market behaviour

  3. availability issues of TDX or other technical problems

  4. incorrect or incomplete data processing or dissemination

  5. invalidation of a trade (e.g., in a mistrade)

  6. special measures taken by TDX under special circumstances or emergency situations

  7. suspension or exclusion of a Participant

  8. incorrect or incomplete data provided and/or published by an issuer

  9. transfer of digital assets to the wrong address, whether internal or external to Taurus, resulting in the partial or total loss of digital assets

  10. hacking of Participants resulting in but not limited to loss of funds or inaccurate orders and transfers. In such a case, Taurus reserves the right to exclude the Participant.

Taurus assumes no liability for claims that go beyond direct damage, such as for example, compensation for indirect damage or consequential damage such as profit losses or additional expenses.

12. Fees

Taurus publishes fees on its website www.t-dx.com.

13. Final provisions
