Subscribe to our newsletter

QuantHouse continues to build out its qh API Ecosystem with the addition of Jane Street Financial’s systematic internaliser (SI). Through its SI, Jane Street offers liquidity for more than 2,000 single stocks from the Cboe Europe universe, with a focus on small and mid-cap names.

Jane Street adds to SIs already connected into the qh API Ecosystem, including Sun Trading and Virtu Financial, and its SI can be accessed via a single API built and maintained by QuantHouse.

Slawomir Rzeszotko, head of institutional sales and trading, Europe at Jane Street, notes that the qh API Ecosystem link will offer clients seamless and cost-efficient connectivity to the company’s liquidity through the QuantHouse QuantFeed and QuantLink mechanisms. He adds: “As MiFID II has brought in sweeping changes industry-wide, the continued growth in our trading volumes is a testament to the execution quality offered by our SI.”

Reflecting the changes made by MiFID II, Stephane Leroy, co-founder and chief revenue officer at QuantHouse, says: “MiFID II has changed the liquidity landscape dramatically. To make it easier for clients to access this fragmented liquidity, QuantHouse offers simple, easy access through one API to the Jane Street SI, regardless of the trading system or what country that client operates in.”

The QuantHouse API Ecosystem is a global initiative with the objective to provide a framework within which capital markets participants can quickly and easily gain access to multiple trading venues, technologies or applications through standard APIs. It houses buy- and sell-side participants, exchanges, prime brokers, trading venues, hedge funds, market makers and other financial services partners and vendors.
