Since it was set up in 1989, MEFF has been developing and fine-tuning its proprietary system. This system has helped to make the Spanish options and futures exchange one of the most secure and efficient anywhere in the world. This system is a complete front-to-back system, as MEFF has provided its members with several types of terminals that enable integral control over the entire derivative cycle (orders, cross operations, assignments and transfers, exercise instructions, filters, risk control, daily settlement at the security holder level, etc.)

The architecture is open and adapts with the evolving needs of the exchange and clearing house that it supports. This has enabled its implementation in other markets.
