Show general information about ToTV workflows

The DSB has extended its service to assist with the process of identifying those ISINs that Traded on a Trading Venue (ToTV) and underlying Traded on a Trading Venue (uToTV) by providing ToTV/uToTV indicators. This was requested by the industry via the Product Committee and broader consultation.

In the event of the UK leaving the EU without an implementation period: following the FCA statement published on 1st February 2019, that the FCA will be replacing the ESMA FIRDS Reference Data system for the UK, the DSB will be adding support for FCA FIRDS contingent on the FCA going live on 1st April 2019. Details are available in the notification published here.

This service is available in both UAT and production. Please refer here for the listed issues regarding the ToTV Service.

The DSB is using FIRDS* data for the initial implementation of ToTV. As trades and quotes that occur on a trading venue and are submitted to ESMA, are then made available to public the next day by ESMA. The DSB will collate the FIRDS data and derive the ToTV/uToTV indicators and make the data available via all the existing connectivity methods to the DSB:

  • GUI
  • File Download
  • ReST API
  • FIX API

In addition to the ToTV/uToTV indicators, the DSB will provide other ESMA sourced data:

  • complete FIRDS Reference Data record for OTC and non-OTC instruments
  • complete FIRDS Transparency Data record for non-equity instruments, including:
  • Liquidity Flag
  • Pre-Trade Large in Scale (LIS) Threshold
  • Pre-Trade Size Specific to The Instrument (SSTI)
  • Post-Trade Large in Scale (LIS) Threshold
  • Post-Trade Size Specific to The Instrument (SSTI)

* Financial Instruments Reference Data System by ESMA

 

DSB ToTV/uToTV flag explained

 

The DSB’s core service is to provide ISINs for OTC derivatives.  Additionally, the DSB provides a service extension to assist with the process of identifying those ISINs that are Traded on a Trading Venue (ToTV) and those that have an underlying instrument that is Traded on a Trading Venue (uToTV). Also included is ESMA sourced data including reference and transparency data.

General information:

  • The DSB has implemented its ToTV/ uToTV service for all instruments not in scope of the ESMA opinion on OTC Derivatives traded on a trading venue (Ref. ESMA70-156-117), including implementation for cash products and ETDs
  • The goal of the current implementation model is to allow users to integrate with the service immediately, so that the future extension of the service to OTC Derivatives that are in scope of the above mentioned ESMA ToTV opinion can be seamless
  • The DSB ToTV and uToTV indicators, as well as the other ESMA sourced data are available alongside the ISIN in a separate JSON file. Users have access to the DSB’s ToTV/ uToTV service via the web-interface, the file download process and on a programmatic basis (via FIX and ReST)
  • The DSB should not to be treated as a golden source of ToTV or uToTV data and should be one input into a multi-factor determination by each user
  • The DSB makes available all records published to FIRDS for reference data purposes alongside accompanying transparency reporting information
  • Users are requested to read the DSB ToTV Current Operating Model specification document which provides detailed information on the scope and application of the DSB’s ToTV and uToTV flag setting process. The document also provides answers to a broad range of user queries
  • All DSB ToTV and uToTV flags are set to “false” unless deemed to be “true” based on the ruleset in the table published below


The DSB applies the following rules to OTC Derivative instruments where the ISIN reported to FIRDS was issued by the DSB:

  • For instruments within the scope of the ESMA opinion published in May 2017, the DSB ToTV flag is set to False pending further clarification from ESMA about the specific attributes that determine ToTV
  • The DSB uToTV flag is set to True if one or more of the underlying instruments are non-OTC derivatives and at least one of which has been reported to FIRDS by a DSB recognized RM/ MTF/ OTF
  • The DSB uToTV flag remains set to False in any of the following scenarios: the underlying is an OTC derivative; the underlying ISIN has not been reported to FIRDS by a DSB recognized RM/ MTF/ OTF, the underlying instrument is an index or reference rate, an LEI underlying is an LEI, the underlying instrument is a basket containing non-ISIN values


The DSB applies the following rules to non-DSB ISINs i.e. mainly non-OTC Derivative instruments:

  • The DSB ToTV flag is set to True where the instrument was reported to FIRDS by a DSB recognized RM/ MTF/ OTF
  • The DSB uToTV flag is set to True where one or more of the non-OTC derivative underlying ISINs haму been reported to FIRDS by a DSB recognized RM/ MTF/ OTF
  • The DSB uToTV flag is set to False in all other scenarios
