Exchange Background, Interface, and Restrictions
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.
The exchange is regulated, controlled, and supervised by the Spanish financial authorities (including the Comisión Nacional del Mercado de Valores and Ministerio de Economía) and recognized by Swiss and British Supervisory Authorities as an authorized exchange. The CFTC has also authorized the offering of bond, futures, and options contracts in the US by granting the “Part 30 Exemption” to all exchange members.
A separate HF MEFFGate interface is provided by the exchange for public prices (M3.3) and private orders data (T3.3). The MEFF Gateway 7.17.20 or higher connects to the exchange interfaces via 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.
You have two options for connecting to MEFF:
- TTNET™, which is TT’s fully managed hosting solution. TTNET enables traders to quickly and reliably access MEFF and other major exchanges through TT’s proven high-performance global market connectivity solution.
- Your own connectivity, which can be obtained by contacting the exchange’s support desk at Techservices@grupobme.es. Options include direct, indirect, or proximity connections, as well as VPN.
Required Connection Information
Prior to installation, you must complete the following tasks:
- To connect to the HF MEFFGate FIX interface platform, you need to order new market data and order routing sessions directly from the exchange. Send inquiries to the exchange at MEFFTechnicalHelpdesk@grupobme.es. Existing customers will receive new primary and backup IP and port information, and will need to apply the new IP and port credentials to their existing FIX sessions to log in to the HF MEFFGate platform.
MEFF supports FIX sessions on both the old and new platforms running simultaneously. For that reason, it’s possible to run your existing TT MEFF Gateway and TT MEFF Gateway 7.17 in parallel while you transition users to the HF MEFFGate platform.
- Obtain a unique set of public interface connection (M3.3) credentials for the Price Server. This set includes a member ID, user ID, password, primary and backup IP addresses, and port number.
- Obtain a unique set of private interface connection (T3.3) credentials for the Order Server. This set includes a member ID, user ID, password, primary and backup IP addresses, and port number.
Additionally, you must work with the exchange to properly configure the following:
- Member ID Configuration: The exchange configures two types of member IDs: TRADER and MULTI-TRADER. To properly view and manage orders for your membership, you must request that MEFF configures your member IDs to TRADER before attempting to trade on the exchange.
- Account Numbers: When connecting to the exchange with a clearing firm or external account, you may need to request five-character account numbers from the exchange.
- Market Order Filters: You must contact the exchange to configure the following mandatory filters for the production environment:
- Price Filter: The exchange uses this filter to determine the limit price it assigns to market orders.
- Volume Filter: This filter provides additional risk management.
In addition, the person who performs the installation must perform the following tasks:
- From the customer, obtain the connection information used by the Price and Order Servers.
- Identify all sets of trader information.
When configuring membership with the exchange, all customers must confirm the following with the exchange:
- User Transaction Limit
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.
To ensure proper order handling, you must request that MEFF sets the order limit to the highest possible value.
- Price Filter and Volume Filter
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, refer to the following MEFF Circular located at:
The MEFF Gateway offers contracts based on the following products:
- IBEX-35 mini- and standard-size Equity Index Futures and Options
- Spanish and European Single Stock Futures
The exchange may change its listed products at any time. For currently listed products, contact MEFF or visit their website at http://www.meff.es/aspx/Financiero/home.aspx?id=inghttp://www.meff.es/aspx/Financiero/home.aspx?id=ing.
Spanish and European single stock futures are not CFTC-certified, meaning they are unavailable for trading in the United States.
The contract names include the instruments’ expiration date and settlement convention. For example, an August IBEX MINI® (FIEM) contract is listed as: 21AUG11-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.
The following lists the difference between American and European style options:
MEFF offers products in the following classes:
- Equities (Market Data only)
MEFF divides its trading hours into the following market states (all times listed in Central European Time (UTC+1)):
8:30 - 9:00
