Hire a REST API developer to connect your strategies, Python or C# applications and trading platforms to broker and crypto exchange APIs, market data providers and external services — or to build an API for your own trading system.
Custom REST integrations with brokers, exchanges, trading platforms and data providers.
A REST API lets one program ask another to do something over the internet — place an order, return the account balance, send price history. Brokers, crypto exchanges and data providers widely use REST to let trading software connect to their systems.
Our REST API developers build both sides of these connections: external applications in Python or C#, and the components inside trading platforms in each platform’s own language. Every integration is tested on demo or sandbox accounts where the provider offers them, and delivered with source code and full IP ownership.
Connect what you already run, or build what is missing — each integration is designed around the API it works with.
Connect an existing strategy, a Python or C# application, or a new trading bot to a broker or crypto exchange API — place, modify and cancel orders and read the account. A bot built this way can run on a VPS with no trading terminal open.
Link MT4, MT5, NinjaTrader, cTrader and other platforms with external services — Python analytics, models, risk checks, signal services, trade journals and licensing — through the component each platform supports.
Historical prices, quote snapshots, fundamentals and news from data providers, delivered into your strategies, scanners and research tools in the format they need.
An API for your own trading application: control it from a web panel or mobile app, publish signals to other systems, and give team members or subscribers access to its data.
Positions, trades, balances and available P&L figures passed into dashboards, journals and reports — with executions and positions matched across systems so each one shows the same picture.
Fix authentication failures, rejected requests and misread responses, or move an integration to a new API version or a different provider when the old one changes or closes.
Not every integration fits a predefined category. Send the API documentation or its name, what the integration should do, and any existing code — we will tell you what is possible and what it would take.
What your system connects to decides how the integration is built. The examples below are grouped by the route it takes.
Your provider isn’t listed? If it publishes a REST API, it can usually be connected. Send us its name or documentation and we will confirm what is possible.
Three typical projects, each built around a different kind of API.
A strategy runs on a VPS, checks its conditions on a schedule and sends orders straight to the broker’s REST API. No trading terminal is involved.
Before each trade, an Expert Advisor in MT4 or MT5, a NinjaTrader strategy or a cTrader cBot asks an external service to calculate the position size and check exposure across accounts, then trades with the answer.
An application collects trades and positions from several broker APIs throughout the day and keeps one trading journal and dashboard up to date.
A trading integration has to cope with what happens between requests. Which of these apply depends on what the integration does and what the API supports.
Access is renewed automatically where the API supports it. Where the provider requires a new login, the integration detects it and alerts you.
Requests are paced to stay within the limits the broker or exchange sets.
After an order is sent, its status is checked — accepted, rejected or pending — and a rejection is recorded with its reason.
Before a request is repeated, the order’s current status is checked first, so a retry does not add a second order.
After a restart or a lost connection, positions and open orders are reloaded before trading resumes.
REST handles requests. Many providers also push live updates over a separate connection — WebSocket at some, HTTP streaming at others, such as TradeStation. A streaming connection helps when software must react to live prices or order updates; loading history, reporting or licensing usually work with REST alone.
Your software asks and the API answers: place or cancel an order, read positions and balances, load price history.
Prices, fills and account changes pushed to your software the moment they occur, without asking again.

Send the API or platform you want to connect, what the integration should do, and any existing code. For broker APIs, tell us the account type and whether API access is already enabled.
Receive the integration and its connector components, source files included in the scope, and instructions for setup and use. We walk through the specified behaviour and provide technical support under the agreed terms.
REST integrations from a team that builds both trading platform software and the services it connects to.
We build Expert Advisors, NinjaScript and cBots as well as the services they talk to, so both ends of an integration are designed together.
Integrations are checked on demo or sandbox accounts, where the provider offers them, before they trade real funds.
Requirements, deliverables, fixed price and acceptance examples are agreed before development begins.
An NDA is available on request. Source code and full IP ownership are transferred on delivery.
Setup help, configuration explanations and technical answers within the agreed support scope.
Feedback from clients across our custom trading software projects.
Practical answers about broker APIs, platforms, access and connection types.
A REST API lets one program ask another to do something over the internet — place an order, return the account balance, send price history. REST API trading integration connects your strategy, application or trading platform to a broker, exchange or data provider in this way, so the work happens automatically.
Yes, when the broker or exchange offers a trading API that accepts orders directly. The bot then runs on a server or VPS with no terminal open. Some broker interfaces still need their own software to be running, which we confirm before the project is scoped.
Yes. We review your Python or C# code, add the connection to the broker or exchange API, and keep your trading logic as it is. If the application is written in another language, send it and we will assess it.
Yes, through the component each platform supports. MT4 and MT5 connect to external services through an Expert Advisor. NinjaTrader connects through a NinjaScript Add-On in the desktop platform, or through its Trade API where available. cTrader connects through a cBot or through its Open API.
Usually, yes. Many brokers require API access to be enabled, an application to be approved, or a specific account type, and availability can depend on the region. We check the provider’s requirements before quoting.
It depends on the task. REST handles requests — placing orders, reading the account, loading data. A streaming connection adds prices and order updates as they happen, which matters for strategies that react in real time. Providers deliver streams differently, over WebSocket or HTTP streaming, so the choice is made per provider.
Yes. A custom REST API lets you control a trading application from a web panel or mobile app, publish signals to other systems, and give team members or subscribers access to data.
Yes. We find what changed — authentication, request format or the API version itself — and update the integration, or move it to a new provider when the old API is closed.
The API or platform you want to connect, what the integration should do, and any existing code. For broker APIs, also tell us the account type and whether API access is already enabled.
Send the API or platform, what the integration should do, and any existing code. We will review it and outline a practical scope for your REST API project.
