Custom Development for Prop Trading
We build the systems behind your trading edge
Trading Pairs is a boutique development studio that builds custom software for proprietary trading firms. From execution engines to risk dashboards — we ship production systems that traders depend on.
How We Work
We embed with your team, not around it
Our engineers sit alongside your traders and quants. We learn your strategies, your language, and your edge — so the software we build actually fits how you work.

What We Build
Software that performs
under real market pressure
Every line of code is written with latency, reliability, and the trading floor in mind.
⚡
Execution Engines
Low-latency order management and execution systems built for speed-sensitive strategies across equities, futures, and crypto markets.
📊
Risk Dashboards
Real-time risk monitoring and P&L visualization tools that give traders and ops teams instant visibility into portfolio exposure.
🔗
Exchange Integrations
FIX protocol adapters, exchange API connectors, and market data feed handlers built for reliable, high-throughput data flow.
🧪
Backtesting Platforms
Strategy simulation engines with tick-level accuracy, custom factor libraries, and performance analytics frameworks.
🏗️
Infrastructure & DevOps
Co-located server setup, network optimization, CI/CD pipelines, and monitoring tailored for trading system uptime.
🔒
Compliance Tools
Trade surveillance, audit logging, regulatory reporting, and position limit enforcement systems to keep your firm compliant.
"Trading Pairs understood our latency constraints from day one. They shipped our new execution engine in 14 weeks and it's been rock solid since."

Our Approach
We scope it right before building anything
Every engagement starts with discovery. We map your workflows, understand your edge, and architect a solution before writing a line of code.

Our Process
How we take your system
from idea to production
Refined across dozens of engagements with prop firms. Every step minimizes risk and gets reliable software into traders' hands fast.
Discovery & Scoping
We embed with your team — understanding strategies, workflows, pain points, and technical constraints. We map your current systems and find where custom development creates the most leverage.

Architecture & Design
We design the system architecture with latency budgets, failure modes, and scalability baked in from day one. You get a detailed technical design doc before we write a line of code.

Build & Iterate
We ship in 2-week sprints with working software at the end of each cycle. Your team has visibility into every commit, and we demo progress weekly.

Testing & Hardening
Trading systems can't fail quietly. We run load tests, chaos engineering drills, and paper-trading validation under real market conditions.

Our Approach
Principles we build by
01
Domain First
Engineers who understand trading, not just code. Every architect has built systems that run in production at prop firms.
02
Latency-Aware
Performance isn't an afterthought. We profile, benchmark, and optimize throughout — not just in a final tuning pass.
03
Ship to Learn
Working software in front of real users early. We iterate based on actual trading desk feedback — not assumptions.

About Us
A dev studio built for
the trading floor
Founded by engineers who spent years building systems inside prop firms and exchanges. We started this studio because too many trading desks are stuck with generic enterprise software or fragile internal builds.
We're a tight team of senior engineers — no juniors, no outsourcing, no handoffs. Every person on your project has shipped production trading systems before.
Our clients are quantitative trading firms, market makers, and proprietary trading desks who need custom software built by people who understand the domain.
Senior Engineers Only
Every engineer has 8+ years of experience and has built trading systems that run in production.
Domain Expertise
We speak your language. FIX, market microstructure, order types, slippage, circuit breakers — we don't need a glossary.
Founder-Led
A founding partner is on every engagement. You're never handed off to an account manager.
Long-Term Partners
Most clients have been with us 2+ years. We build relationships, not just invoices.
Culture
Small team, big impact
We keep the team lean on purpose. Every engineer is senior, every conversation matters, and every system gets the attention it deserves.
Want to work with us?
We take on a limited number of engagements to maintain quality. Let's see if we're a fit.
