Connect to Interactive Brokers with ZagTrader

Who is Interactive Brokers?

Interactive Brokers is one of the world's largest electronic brokers, recognized for technology-driven execution and broad, low-cost access to global markets. The firm provides direct market access to exchanges, electronic communication networks, and other liquidity sources spanning equities, listed options, futures, foreign exchange, bonds, and funds. Its trading infrastructure is built around automation, smart routing, and electronic order handling, which has made it a long-standing choice for institutions, professional traders, and active market participants seeking direct, multi-market reach.

For asset managers, hedge funds, brokers, and proprietary desks, Interactive Brokers is valued less as a single-venue counterparty and more as a global gateway: a single broker relationship that opens access to a very large number of markets and instruments. Reaching that gateway through a stable, well-monitored, certified connection is a practical requirement for any desk routing institutional flow to it, and that is the role ZagTrader is built to fill.

How ZagTrader connects and routes to Interactive Brokers

ZagTrader provides institutional connectivity to Interactive Brokers through FIX sessions and supported API interfaces, established and tested so that order flow, executions, and acknowledgements travel over resilient, monitored links. The same connectivity supports direct market access (DMA) workflows, allowing desks to send orders through Interactive Brokers to the wide range of venues and liquidity it reaches 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 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 and API 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.

The breadth of markets and assets you can access

Interactive Brokers is best known for the sheer breadth of its market access, reaching exchanges and trading venues across the Americas, Europe, the Middle East, and Asia-Pacific from a single broker connection. Routing through it via ZagTrader's multi-asset platform lets a desk reach that breadth of coverage from one consistent workflow rather than maintaining separate tools per product line or per region. The specific instruments, markets, and services available always depend on a client's own agreements and onboarding with the broker.

• Equities — cash equities listed across a wide range of global markets.
• Options — listed equity and index options for hedging and strategy.
• Futures — exchange-traded futures across major derivatives venues.
• Foreign exchange — FX execution for institutional and professional flow.
• Bonds — government and corporate fixed-income instruments.
• Funds and 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 Interactive Brokers all the way through to booking. Fills captured over FIX and confirmed via drop-copy feed straight into the platform's post-trade processing, so that trades, allocations, and positions are kept consistent across multiple markets and currencies 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 many jurisdictions an Interactive Brokers connection can reach.

Why route to Interactive Brokers through ZagTrader

Routing to Interactive Brokers 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 Interactive Brokers alongside other supported brokers and venues, so traders manage their full book in one place and operations work from one consistent set of records — even when the underlying flow spans dozens of global markets.

FIX and API connectivity with drop-copy reconciliation give desks confidence that what was sent, executed, and booked all agree, while smart order routing and pre-trade controls keep execution disciplined. 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 use Interactive Brokers as their gateway to global markets and beyond.

• One multi-asset OMS/EMS for Interactive Brokers and additional brokers and venues.
• FIX, API, and DMA connectivity with drop-copy reconciliation.
• Smart order routing and pre-trade compliance and risk controls.
• Integrated post-trade flow from execution through booking and reporting.
• Scales to more counterparties, asset classes, and global markets without re-platforming.
