Turquoise trading interface

The interface provides trading access to the securities market based on MTF Turquoise platform, a part of LSE Group.

Module Functions

  • Upload of reference data from a directory.
  • Forwarding and cancellation of orders as well as transmission of trading data in the following modes:

    Turquoise Integrated Order Book (Lit) — a double auction mode with standard execution of orders based on ‘visible quotes’.

    Turquoise Dark Midpoint Order Book (Dark Pool) — a mode, where orders are sent to ‘invisible quotes’ and executed at the same price calculated as an average value between bid and offer. (The mode features the service — Turquoise Block Discovery™ for the matching of undisclosed Block Indications and the innovative mechanism — Turquoise Uncross™ that provides randomized uncrossings which are ideal for larger and less time sensitive of passive orders).

  • Transmission of Level I and Level II market data (the Lit mode) and anonymous trades (Lit and Dark Pool modes).
  • On-exchange order replacement and order cancellation.

Access to MTF Turquoise comprises market data, transaction and Drop Copy connections:

  • The market data connection comprises several data channels with each transmitting data on a specific market segment. Connection is established through the MITCH exchange protocol which is based on UDP and TCP network protocols.
  • The transaction connection serves for order forwarding/cancellation and trade reporting. The connection is established through TCP and FIX network protocols.
  • The Drop Copy connection serves for transmitting data on orders and trades to the QUIK server. The connection is established through TCP and FIX network protocols.
