Connect to Lime Brokerage with ZagTrader

Who is Lime Brokerage?

Lime Brokerage, also known as Lime Trading, is a US broker that has built its reputation on speed and execution performance. Rather than positioning itself as a full-service generalist, Lime is best known for high-performance, low-latency direct market access designed for active traders, professional trading firms, and quantitative and systematic strategies that are sensitive to execution quality and latency. Its technology-led model — fast order entry, low-latency connectivity, and infrastructure tuned for high message rates — has made it a recognized name among traders who measure their edge in microseconds and fill quality.

For hedge funds, proprietary trading firms, and active professional desks, Lime is valued as an execution-focused gateway to US markets where latency and reliability matter. Reaching that kind of execution capability through a stable, well-monitored, certified connection — without giving up pre-trade control, risk checks, and a consolidated view of the book — is a practical requirement for any institutional desk routing flow to it, and that is the role ZagTrader is built to fill.

How ZagTrader connects and routes to Lime Brokerage

ZagTrader provides institutional connectivity to Lime Brokerage 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 low-latency direct market access workflows, letting desks send orders through Lime to the markets 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, desks can pursue low-latency execution through Lime without sacrificing the controls and consolidated records that institutional trading demands.

• FIX and API sessions for order entry, execution reports, and acknowledgements.
• Low-latency direct market access 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.

Low-latency execution for active and quantitative trading

Lime's distinguishing characteristic is execution performance, and ZagTrader is designed to let desks take advantage of that while keeping institutional discipline in place. For active, high-volume, and systematic strategies, the combination is straightforward: orders are generated and risk-checked within ZagTrader's OMS/EMS, then routed over FIX or API to Lime for fast, low-latency execution, with fills and status flowing back to the same blotter in real time.

This matters most for traders who care about how an order is handled, not just whether it is filled. Pre-trade risk limits and compliance rules are applied before orders are sent, smart order routing decisions are made within the platform, and every execution is captured and reconciled centrally. The specific markets, order types, and execution services available always depend on a client's own agreements and onboarding with Lime; ZagTrader's role is to make that low-latency access usable from a controlled, consolidated, multi-asset workflow.

• Low-latency execution access suited to active and systematic strategies.
• Pre-trade risk limits and compliance applied before orders are routed.
• Smart order routing decisions handled within the OMS/EMS.
• Real-time fills and order status captured on a single consolidated blotter.
• Execution services available subject to the client's own agreements with Lime.

Post-trade, settlement, and reporting

Fast execution still has to be booked accurately, and ZagTrader is built to carry flow routed to Lime Brokerage all the way through to settlement. 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 without manual re-keying — even at the high message rates that active and systematic trading can generate.

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 US 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.

Why route to Lime Brokerage through ZagTrader

Routing to Lime Brokerage through ZagTrader means pairing Lime's low-latency execution with a multi-asset front-to-back platform that handles routing, risk, compliance, and post-trade — instead of bolting a fast execution pipe onto a patchwork of disconnected systems. A single OMS/EMS blotter spans Lime alongside other supported brokers and venues, so traders manage their full book in one place and operations work from one consistent set of records.

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 even fast, high-volume 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 active and quantitative desks that use Lime for low-latency execution.

• One multi-asset OMS/EMS for Lime and additional brokers and venues.
• FIX, API, and low-latency DMA connectivity with drop-copy reconciliation.
• Pre-trade compliance and risk controls around fast, high-volume execution.
• Integrated post-trade flow from execution through booking and reporting.
• Scales to more counterparties, asset classes, and markets without re-platforming.
