Hire a C# trading developer for NinjaTrader, cTrader and Quantower strategies, standalone trading bots, broker API integration and focused trading tools — built from your rules.
Platform strategies, standalone bots and practical tools written in C#.
Nordman Algorithms writes C# trading software for traders, prop traders, small funds and trading teams. Our C# trading developers work from trading rules, a written specification or just a plain description — or from existing code that needs finishing or fixing.
The work can live inside a trading platform, in a standalone application, or in the connection between the two. As C# algorithmic trading developers, we build platform strategies, standalone bots and focused tools built for a specific task.
You receive the full C# source and all rights to it when the work is delivered.
C# is the native language of NinjaTrader, cTrader and Quantower. We build strategies, indicators and tools for all three.
NinjaScript is C# running inside NinjaTrader 8, with access to tick data, custom chart drawing and separate add-on windows. Strategies can hand their exits to ATM templates, and add-ons work across the whole platform.
cTrader Algo runs C# cBots and indicators directly inside cTrader, with access to positions, orders and market data on the connected account. Plugins add panels and tools to the platform interface itself.
The Quantower API is used to build C# strategies, indicators and plugins that run inside the platform with the brokers and data feeds connected to it. Plugins can add their own panels to the Quantower workspace.
Standalone bots, broker integrations, focused tools and trade copiers, written by our C# algorithmic trading developers from your rules.
Standalone trading bots and services in C#: your rules turned into signals, position sizing, order handling and risk limits, running on their own outside a trading platform.
C# connected to broker and exchange APIs — Interactive Brokers through TWS or IB Gateway, crypto exchanges over REST and WebSocket — for orders, positions, account data and live prices, with reconnects handled.
Focused programs built for one task, with a simple interface: order entry, trade management, position sizing or account monitoring.
Trades copied or executed across several accounts or brokers, with position size set for each account and open positions checked against every account.
New features, fixes, refactoring and performance work for C# trading code you already have — an interface that freezes on incoming data, updates that fall behind, code that needs splitting into maintainable parts — including projects another developer left unfinished.
Strategies moved between NinjaTrader, cTrader and Quantower — adapted to each platform’s events, data and order handling — or to and from Pine Script, MQL4/5, EasyLanguage or Python, with logic, assumptions and key outputs compared.
Risk rules and account checks in C#: loss and exposure limits, prop firm rules, and alerts when a limit comes close.
C# libraries that connect MetaTrader 4/5 or TradeStation to .NET code — shared calculation modules or data exchange with an external system — with the adapter each platform needs.
We agree the rules, the platform or broker, where the software will run and the acceptance checks with you before any code is written.
Send your trading rules or a description of the tool, the platform or broker you use, and any existing code.
Receive the full C# source, a compiled build where it applies, and setup instructions — plus test results and installation where the project includes them. We walk through the specified behaviour and provide technical support under the agreed terms.
Work with C# trading programmers who build both platform components and the software around them.
We can build the part that runs inside the platform and the external software it works with, so both sides are designed together.
We build and sell our own trade copiers, so executing across several accounts is familiar ground.

An NDA is available on request. Source code and full IP ownership are transferred on delivery.
Setup help, configuration questions and technical answers within the agreed support scope.

Practical answers about C# trading software, platforms and brokers.
NinjaTrader through NinjaScript, cTrader through cTrader Algo, and Quantower. We also build standalone C# programs that connect to brokers such as Interactive Brokers.
It depends on the broker connection. Crypto exchanges and some brokers let a bot connect to their API directly; with the Interactive Brokers TWS API, TWS or IB Gateway has to be running. In both cases the bot trades by your rules without a charting platform.
No. We build focused tools for a specific task — order entry, trade management, position sizing or account monitoring — rather than complete trading platforms.
Yes. We go through the existing code first to see how it is built and what works, agree what is missing, then finish and fix it.
Yes — including between NinjaTrader, cTrader and Quantower. A shared language does not mean a strategy runs unchanged on another platform: events, data and order handling differ, so the logic is adapted. Strategies from Pine Script, MQL4/5, EasyLanguage or Python can be rebuilt in C# too. Logic, assumptions and key outputs are compared, allowing for differences in data and execution.
It depends on your existing code, the libraries you need, whether the tool needs its own interface, and where it will run. NinjaTrader and Quantower work in C#, while cTrader supports both C# and Python; data work and research often suit Python. We suggest one when we see the task.
Yes. You receive the full C# source, a compiled build where it applies, and setup instructions. Source code and full IP ownership are transferred on delivery.

Send your rules or a description of the tool, and the platform or broker you use. We will go through it and suggest the scope and next steps.
