Forex Programmer — Custom Trading Software Development
Turn your trading idea into working software. BJF’s forex programmers have built 5,000+ custom robots, indicators and scripts since 2005 — from a single indicator to a full automated, latency-sensitive trading system. You describe the strategy; we engineer it, and you own the result.
The BJF forex programming service is bespoke development of automated trading software — robots, custom indicators, scripts, FIX API integrations and full trading systems — built to your exact strategy specification. We have delivered 5,000+ custom projects since 2005 across standard trading platforms, cTrader, JForex and FIX API in C++ and C#. Pricing is by free quote; you keep the intellectual property of the original work, and an NDA is available on request.
What we build
Whatever the degree of complexity, if it can be automated we can build it. Common projects include:
Trading robots & expert advisors
Fully automated systems that execute your strategy — entries, exits, risk management and money management — without a human in the loop.
Custom indicators
Bespoke technical indicators, dashboards and signal tools, from a single custom oscillator to a complete multi-instrument analytics panel.
Scripts & utilities
One-click tools, trade managers, risk calculators, alerting and automation scripts that remove the repetitive parts of your workflow.
FIX API integrations
Low-latency execution and data integrations in C++ and C# for direct market access, bridges and custom connectivity.
Arbitrage & HFT systems
Latency-sensitive, multi-account and high-frequency logic — our home turf, since we build our own arbitrage software.
Fixes, upgrades & migration
Not only new builds — we optimise, extend, debug and migrate existing bots, indicators and scripts to new platforms.
Platforms & technologies
We develop across the platforms and languages serious automated trading actually runs on:
| Platform / technology | Typical use |
|---|---|
| FIX API (C++ / C#) | Direct market access, low-latency execution, custom bridges and connectivity. |
| cTrader | Automated strategies (cBots) and custom indicators on the cTrader platform. |
| JForex (Dukascopy) | Robots, indicators and tools for the JForex environment. |
| Standard trading platforms | Expert advisors, platform scripts and custom indicators via standard platform bridges and APIs. |
| Custom APIs & services | Broker/exchange REST and WebSocket integrations, data pipelines and back-end automation. |
How it works
Send us your idea
Describe the strategy, indicator or tool you want built — in as much or as little detail as you have. Request our NDA first if you’d like your idea protected before you share it.
Get a free quote
We evaluate the coding price and time for free and come back with a clear estimate before you commit to anything.
We build it
Our developers turn your specification into working software, checking in with you as the logic takes shape so it matches your intent.
Delivery & testing
You receive the finished tool, tested against your requirements, ready to run on your platform and account.
Support & refinement
We stand behind what we build — with help getting it running and refining it as your needs evolve.
Your idea, your software
When the work is based on your original idea, the intellectual property is yours. You are commissioning bespoke software, not licensing a shared product — and what we build for you stays yours.
An NDA is available on request before you share anything sensitive, and original work is delivered as your property. Your edge stays your edge.
Why BJF
26 years, 5,000+ projects
Custom trading software since 2005 across thousands of client projects — depth of experience you can’t fake.
Real arbitrage & HFT expertise
We build and run our own arbitrage and HFT tools, so latency, feeds, FIX API and multi-account execution are core skills — not buzzwords.
Any complexity, honestly scoped
From a simple indicator to a full trading system — with a realistic estimate of price and time up front, and no overselling.
Your IP, your NDA
You own original work and can lock it down with an NDA before you share a single detail.
