General Members more

General Members will be authorised investment firms or credit institutions looking to provide liquidity onto the LMAX order book.

Becoming a member

The process of becoming a General Member on the LMAX MTF consists of two phases: an Integration phase and a Legal & Regulatory phase. During the Integration phase the firm’s ability to connect to LMAX MTF is confirmed. Subsequently during the Legal & Regulatory phase the firm's applicability for membership will be assessed based on the criteria set forth in the LMAX Rulebook, and based on your company’s suitability and appropriateness for trading on LMAX MTF. You will need to complete and sign the application form and also sign the required legal documentation.

Integration may continue in parallel with the Legal & Regulatory phase.

By way of illustration, General Members should expect the following steps in the application process:

  • Applicant firm should firstly assess the FIX API specification to ensure they can connect in line with LMAX MTF connectivity provisions.
  • Applicant firm should review and complete the Application Form to enable a test login to be created. At this stage, the log in and arrangements for testing of the applicant firm’s data into the LMAX MTF test environment will be confirmed.
  • Once testing is complete, the applicant firm should complete the Members’ on-boarding pack (including the Member Agreement and Information Licence Agreement) in full and return to LMAX Limited for assessment. Integration and testing may continue through this process.
  • Upon Membership approval, the applicant firm will be notified of the account details and an appropriate timetable will be drawn up for on-boarding.
