Information Systems

OMIClear business model is built over the following that is supported by reliable and robust systems. The main system for its core activities as CCP is called ‘MiClear’.

In terms of market cycle, once the orders are matched (in case of continuous trading or auctions) or once the bilateral trades (OTC deals) are submitted in the connected Market, the resulting deals are registered in OMIClear for clearing and settlement based on a Straight Through Processing (STP) solution.

For further details on the trades registration process and the moment at which OMIClear becomes the Central Counterparty (CCP) of the registered trades click here.

The MiClear system was designed to provide market participants with all necessary clearing and settlement information in an efficient way, on a close-to-real-time basis, allowing for two main access modes:

  • Web-based frontend, that includes all functionalities available to participants;
  • XML API for systems integration.


The MIClear's API is a read-only API, available to all participants, for extracting and integrating clearing data (public and confidential), related to trading activity performed over OMIClear eligible contracts. This API follows the XML Web Services open standard which is platform agnostic and widely deployed.

The information provided by the MiClear system includes current and historical data including:

  • Trades,
  • Net position (intraday and end-of-day),
  • Settlements of P&L during contract trading and delivery periods,
  • Volume fees,
  • Intraday and end-of-day margins,
  • Collateral deposited with the CCP, monthly deposits/withdrawals and applicable interests,
  • Monthly settlement statistics, results on back tests and stress tests.
