International Order book

The IOB enables investors to unlock the potential of some of the world’s fastest growing markets through a single central electronic order book. It offers easy and cost efficient direct access to securities via depositary receipts from over 44 countries, including those in Central and Eastern Europe, Asia and the Middle East.

The market has grown rapidly since its inception in 2001, with Gazprom, Sberbank and Lukoil being amongst the most heavily traded securities on the London Stock Exchange.

With similar order functionality as found on SETS, IOB provides a deep, liquid market. This visible liquidity is supplemented by the potential to obtain price and / or size improvement on execution. This is made possible by the minimum size for hidden orders and the minimum peak of iceberg orders both being set at around US$14,000, encouraging the provision of larger un-displayed orders. Price improvement is further enhanced by the option to automatically update a hidden order to the mid of best visible bid / offer.

Important changes from Monday 10 February 2014:

  • The opening auction will start at 07.50, with the regular trading starting at 08:00 (subject to any random 30 second periods, or price or market order extensions).
  • The Closing Price Crossing session (CPX) will be available until 4pm. The closing auction will still begin at 15:30 and finish at 15:40(subject to any random 30 second periods, or price or market order extensions).
  • Gazprom, Lukoil, Sberbank, Rosneft, Novatek and MMC Norilsk Nickel are moving to the FESE1. The IOB securities which should be included on this tick table will be reviewed every 3 months.

IOB Clearing
In line with SETS and the Turquoise Derivatives IOB service, the IOB benefits from a Central Counterparty (CCP) clearing service around 100 of the most heavily traded securities, ensuring anonymous pre and post trading, along with full counterparty protection. A buyer protection service is available allowing participants to make elections in unsettled, cleared trades during a corporate action. A manual buyer protection election service is operated by LCH.Clearnet for IOB corporate actions. To activate an election in a specific corporate action (currently at no cost) requires the submission of a Buyer Election Notice to LCH.Clearnet. This can be found as Appendix 2D.F of Section 2D at the following link:
