Introducing FLEX-FA

XFA Partners with Genesis Global to Deploy Automated Quoting System for FLEX Options
Innovative new platform demonstrates XFA’s continued commitment
to meet clients’ liquidity needs

Genesis low-code technology delivers XFA solution for highly customized options in two months

CHICAGO and MIAMI – November 15, 2023– X-Change Financial Access (XFA), a division of
Marex and a leading execution broker for exchange-traded derivatives, and Genesis Global, the
low-code application development platform purpose-built for financial markets organizations,
today announced a partnership to automate quoting for flexible exchange options (FLEX
options).

Called FLEX-FA, the new platform streamlines intraday quoting of FLEX options, enhancing the
speed and reach of XFA’s brokerage services. Unlike traditional options, the FLEX market does
not benefit from a continuous quote stream. Therefore, innovations like FLEX-FA, which
standardize and automate request-for-quote (RFQ) processes, benefit end users by increasing
liquidity and promoting best price execution.

FLEX-FA was delivered in two months by Genesis.

“FLEX-FA enables us to provide high levels of service to clients amid dramatic growth in volume
and order complexity in the FLEX option market,” said Andrew Geye, Head of Structured
Products at XFA. “In partnering with Genesis, we have developed a scalable, modern RFQ
solution which improves the price discovery process by enhancing speed, accuracy and
efficiency.”

“Working with innovators like XFA to automate key parts of fixed income markets is a key
strength of Genesis,” said Stephen Murphy, CEO and co-founder of Genesis Global. “Built in
only two months, the FLEX-FA platform demonstrates that trading operations for even the most
bespoke financial products can migrate from spreadsheets and manual processes to modern,
enterprise quality solutions which benefit brokers, market makers and end users, alike.”

Central to FLEX-FA is a Genesis-built FIX message hub and RFQ workflow manager which
enables XFA to electronically distribute RFQs to multiple market makers, who can return quotes
via FIX back to XFA. The system aggregates RFQ responses and customized interfaces, designed
by Genesis, make it easy for XFA to place orders with winning quotes.

“With FLEX-FA, we help our customers reach a broad audience of liquidity providers, regardless
of how complex the order might be. The platform also enables market makers to quote with
confidence and accuracy, which is important in an increasingly active marketplace,” added
Andrew Geye.

FLEX options are index options products that offer the security of an exchange-traded product
while offering the writer and purchaser the ability to negotiate exercise style, expiration date,
strike price and other variables in the option.

Marex, the parent company of XFA, is also a client of Genesis. Marex uses Trade Allocation
Manager, the modular, flexible, cross-asset class middle office solution from Genesis.
