The Mercado Español de Futuros Financieros, or MEFF, was launched November 1989 and is the official Spanish exchange for financial futures and options. The exchange is a subsidiary of Bolsas y Mercados Españoles (BME Group), which is comprised of the Madrid, Barcelona, Bilbao and Valencia stock exchanges, MF Mercados Financieros, Iberclear and BME Consulting.
MEFF’s primary activity is trading, clearing, and settling of futures and options contracts on equity index IBEX 35 contracts. MEFF acts as both the market and the clearing house for derivative products in Spain. The integration of exchange and clearing house facilitates risk management in real time and simplifies the mark-to-market and settlement-at-expiry procedures.
TT® supports the following:
A separate HF MEFFGate interface is provided by the exchange for public prices (M5.0) and private orders data (T5.0). TT® connects to the exchange interfaces via FIX 5.0 SP 2.
FIX API mapping for connection, account, and user fields in Setup is based on FIX 5.0 SP 2.
MEFF operates its matching engine as part of the MEFF S/MART platform's Central Systems, which is maintained in two separate locations (Madrid and Barcelona) for disaster recovery purposes.
Futures and options contracts are registered on Equity Index, Stocks and National Government Bond contracts. The Clearing House receives trades directly from the MEFF Derivatives Trading Platform, and monitors risk and margin of each Clearing Member.
MEFF matches orders based on a price-time priority matching algorithm. This algorithm applies to all the contracts traded on MEFF.
When configuring access to MEFF, confirm the following with exchange:
MEFF configures a per-second order limit on all users. Currently, the exchange sets the maximum limit equal to 300 orders per second on each FIX order session.
Warning: To ensure proper order handling, you must request that MEFF sets the order limit to the highest possible value.
The Price Filter determines the maximum range between possible bid/ask prices and the last traded price. The Volume Filter determines the maximum order size allowable for the member. Failure to establish these filters can result in suspension in trading at the exchange. For guidance on determining and establishing the Price and Volume Filters, contact the exchange at: MEFFTechnicalHelpdesk@grupobme.es.
You can trade the following MEFF products on TT:
Note: The exchange may change its listed products at any time. For currently listed products, contact MEFF.
Contract names include the instrument expiration date and settlement convention. For example, an IBEX MINI® (FIEM) contract is listed as: FIEM 02NOV18-Cash, where “Cash” indicates that the contract is financially, as opposed to physically, settled.
In the TT system, American and European options contracts are displayed with either an “A” (American) or “E” (European) in the options contract name to distinguish between the two options styles. European options may be exercised only at the expiry date of the option, while American options may be exercised at any time before the expiry date.
