Connect to Jane Street with ZagTrader

Who is Jane Street?

Jane Street is a global proprietary trading firm and one of the most active liquidity providers in modern markets. Founded in 2000 and headquartered in New York, the firm operates across major financial centers worldwide and trades a broad range of instruments using its own capital. It is best known as a market maker, continuously providing two-sided quotes and absorbing flow so that other participants can transact efficiently.

The firm is especially well known for its work in exchange-traded funds (ETFs), where it is a prominent authorized participant and market maker, helping keep ETF prices closely aligned with the value of their underlying baskets. Beyond ETFs, Jane Street is active in equities, listed options, fixed income, and other products across global venues. For asset managers, hedge funds, brokers, and banks, a liquidity provider of this scale is a natural execution counterparty — and reaching it through a stable, monitored connection is a practical requirement for any desk that routes flow to it. That is the role ZagTrader is built to fill.

How ZagTrader connects and routes to Jane Street

ZagTrader provides institutional connectivity to Jane Street through FIX sessions, established and tested so that orders, executions, and acknowledgements travel over resilient, monitored links. The same connectivity supports direct market access (DMA) and request-style workflows, allowing desks to send orders to Jane Street and source its liquidity while retaining full control and visibility on the trading blotter.

Connectivity is delivered as part of ZagTrader's integrated Order Management System (OMS) and Execution Management System (EMS). Traders work from a unified blotter, apply pre-trade compliance and risk checks, and use smart order routing logic to direct orders appropriately before they leave the desk. Drop-copy sessions can provide an independent, real-time stream of execution and order-status messages for reconciliation, surveillance, and risk monitoring. Because order management, execution, routing, and post-trade share one platform, there are no brittle hand-offs between disconnected systems.

• FIX sessions for order entry, execution reports, and acknowledgements.
• Direct market access (DMA) order flow with full blotter visibility.
• Smart order routing managed within the OMS/EMS before orders are sent.
• Drop-copy sessions for independent reconciliation and surveillance.
• Pre-trade compliance and risk checks applied before orders leave the desk.

Liquidity and markets accessible through Jane Street

As a global market maker, Jane Street provides liquidity across a wide range of instruments, with particular depth in ETFs. Routing to it via ZagTrader's multi-asset platform lets a desk tap that liquidity from a single, consistent workflow rather than maintaining separate tools per product line. The firm's ETF franchise is a core strength: as an active authorized participant and market maker, Jane Street helps keep ETF quotes tight and closely tracked to the underlying basket, which supports efficient execution for funds and other ETF-focused flow.

The specific instruments, products, and services available always depend on a client's own agreements and onboarding with the firm. Within that scope, ZagTrader provides the connectivity and routing layer that lets a desk reach Jane Street's quotes alongside its other counterparties and venues.

• ETFs — deep liquidity and tight pricing from a leading ETF market maker and authorized participant.
• Equities — cash equities execution across global markets.
• Listed options — equity and index options for hedging and risk transfer.
• Fixed income — liquidity across eligible debt instruments.
• Other instruments available under the relevant client agreements.

Post-trade, settlement, and reporting

Execution is only the first step in the trade lifecycle, and ZagTrader is built to carry flow routed to Jane Street all the way through to booking. Fills captured over FIX, and confirmed via drop-copy where available, feed straight into the platform's post-trade processing, so that trades, allocations, and positions stay consistent without manual re-keying.

The platform supports trade confirmation and allocation, generation of settlement instructions, and reconciliation against counterparty, custodian, and clearing records. Settlement itself takes place through the relevant market infrastructure and the client's own custody and clearing arrangements; ZagTrader's role is to manage the order and post-trade data flow accurately around that process. Reporting and audit-ready record keeping are produced from the same source of truth that runs from order inception, helping desks meet their internal control and regulatory obligations across the jurisdictions in which they operate.

Why route to Jane Street through ZagTrader

Routing to Jane Street through ZagTrader means consolidating execution, routing, risk, compliance, and post-trade onto one multi-asset front-to-back platform instead of stitching together separate systems for each function. A single OMS/EMS blotter spans Jane Street alongside other supported liquidity providers, brokers, and venues, so traders manage their full book in one place and operations work from one consistent set of records.

FIX connectivity and reconciliation give desks confidence that what was sent, executed, and booked all agree, while smart order routing and pre-trade controls keep execution disciplined. For ETF-heavy and multi-asset flow in particular, reaching a deep liquidity provider through a controlled, monitored connection helps desks execute efficiently. As needs grow, the same platform scales to additional counterparties, asset classes, and markets without re-platforming, making ZagTrader a durable foundation for desks that route institutional flow to Jane Street and beyond.

• One multi-asset OMS/EMS for Jane Street and additional liquidity providers, brokers, and venues.
• FIX and DMA connectivity with drop-copy reconciliation.
• Smart order routing and pre-trade compliance and risk controls.
• Strong fit for ETF and multi-asset flow from a single workflow.
• Scales to more counterparties, asset classes, and markets without re-platforming.
