Modern trading platforms operate in highly complex environments. They must connect to liquidity providers via FIX, handle massive volumes of real-time data, process trading requests instantly, and expose management capabilities to traders and administrators through APIs. While REST APIs have become the standard interface for such systems, managing a trading platform backend purely through raw REST APIs presents significant challenges—especially for users without deep technical backgrounds.

The Challenges of Managing a Trading Backend with Raw REST APIs

At first glance, REST APIs appear simple and universal. However, in a real trading platform, backend operations are rarely linear. A single user action—such as placing an order, updating risk limits, or querying positions—may trigger multiple backend processes, validations, and state changes.

For non-technical users, interacting with dozens or even hundreds of REST endpoints can quickly become overwhelming. Each API call requires precise parameters, strict sequencing, and careful error handling. This complexity makes raw REST APIs unsuitable for traders, risk managers, or business operators who want to focus on trading logic rather than low-level system integration.

Asynchronous Complexity in Trading Systems

Trading platforms are inherently asynchronous. Market data updates, order execution reports, margin changes, risk alerts, and account notifications all occur independently and in real time. Traditional REST APIs, which are request-response based, struggle to model this behavior in a clear and intuitive way.

As a result, users often need to combine REST calls with polling mechanisms, state tracking, or custom message-handling logic. This not only increases development effort but also raises the risk of errors, delays, and inconsistent system states—especially for users without professional software engineering experience.

Why Fintechee Introduced FiSDK

Fintechee recognized that a large portion of quantitative traders and platform operators do not come from a traditional software development background. These users need powerful backend access, but they also need simplicity, clarity, and reliability.

To address this gap, Fintechee introduced FiSDK, an API toolkit designed to abstract, simplify, and orchestrate the underlying REST APIs of the Fintechee trading platform. Instead of exposing raw backend complexity, FiSDK repackages core functionality into a clean, JavaScript-based interface that is easier to understand and use.

FiSDK as a Bridge Between Traders, Admins, and the Backend

FiSDK acts as a logical bridge between users and the Fintechee backend. It provides two core interaction patterns:

• Command-style APIs for sending requests, such as configuration changes, queries, or trading-related actions

• Event subscription mechanisms for receiving asynchronous notifications from the server

This design allows traders and administrators to interact with the system in a natural, event-driven way—without worrying about how backend processes are chained or synchronized. Whether managing risk, monitoring positions, or overseeing platform operations, users can focus on what they want to achieve rather than how the backend executes it.

The Key Value Proposition of FiSDK

The core value of FiSDK lies in accessibility without sacrificing power. It enables:

• Simplified backend management for non-technical traders and operators

• Clear handling of asynchronous trading events

• Faster development of custom dashboards and management tools

• Reduced learning curve through plain JavaScript, without complex frameworks

• A unified interface that reflects real trading workflows

By introducing FiSDK, Fintechee makes advanced trading infrastructure usable by a much broader audience, empowering traders, admins, and white-label operators to build, manage, and scale their platforms with confidence.
