Choose your trading mechanisms

For customers wishing to roll their open interest or to utilize calendar spreads as a cleared alterative for FX Swaps, they can use both the CLOB and Block liquidity.

Central limit order book

  • The CLOB provides firm pricing in an all-to-all, anonymous, and credit-agnostic environment.
  • In the context of calendar spreads for the quarterly roll, this provides a unique source of liquidity and price discovery for FX swaps given the firm pricing that is underpinned by ‘hard’ credit.
  • The CLOB also supports customers trading passively via resting orders, enabling customers to avoid paying and to potentially even earn the spread on their positions.
  • Pricing in the CLOB for both outright futures and spreads can be accessed via multiple front-end platforms including CME Direct, Bloomberg, TT, CQG, and Refinitiv.
  • The Bloomberg tickers for EUR FX futures and spreads are: ECA [Curncy] / ECM1ECU1 [Curncy]
  • The minimum price increment for a calendar spread in the CLOB is 0.2 of a pip for EUR, JPY, CAD, and AUD.


  • Block trades are privately negotiated on a relationship basis away from the CLOB .
  • These trades are negotiated on a disclosed basis, enabling large orders to be executed at one single price using an existing OTC relationship and liquidity of chosen counterparts.
  • Over 20 entities are now available for providing block prices in listed FX products.
  • The minimum price increment for blocks in G10 currency pairs is 1/10 of a pip.
