Industry Expertise
Prop Trading
Proprietary trading operates at the intersection of speed, precision, and risk. Microseconds matter. A single miscalculation in position sizing or risk exposure can wipe out a day's profits in an instant. Lemorange builds the trading platforms, execution engines, and risk management systems that prop trading firms rely on to compete in modern financial markets. Our architectures are optimized for minimal latency, maximum throughput, and the kind of deterministic performance that traders demand. From FIX protocol connectivity to real time P&L dashboards, we deliver systems that give trading desks a genuine technical edge.
Understanding Your Domain
Challenges We Solve
Every industry has unique technical and operational challenges. Here are the ones we address most frequently in prop trading.
Ultra Low Latency Requirements
In proprietary trading, speed is a competitive advantage measured in microseconds. Every layer of the system, from network I/O to order serialization to execution routing, must be optimized to minimize latency.
Market Data Feed Integration
Trading systems must ingest, normalize, and distribute market data from multiple exchanges and data vendors simultaneously. Each feed has its own protocol, format, and reliability characteristics.
Real Time Risk Management
Positions change every millisecond. The risk management system must calculate exposure, margin requirements, and P&L in real time across all instruments and trading desks without introducing latency into the order flow.
FIX Protocol Complexity
The Financial Information eXchange protocol is the standard for electronic trading, but every counterparty implements it slightly differently. Connecting to brokers, exchanges, and prime brokers requires careful adaptation and testing.
System Determinism and Reliability
Trading systems must behave predictably under all conditions. Garbage collection pauses, network jitter, and resource contention can all cause unexpected latency spikes that cost real money.

Our Advantage
Why Choose Lemorange for Prop Trading
Performance Engineering Expertise
We understand the techniques required for genuine low latency systems: lock free data structures, memory pooling, kernel bypass networking, and GC tuning. Our trading systems are measured in microseconds, not milliseconds.
Financial Markets Domain Knowledge
Our team understands market microstructure, order types, execution venues, and the regulatory landscape. We speak the language of trading desks because we have built systems for them.
Co Location Ready Architecture
Our systems are designed and tested for deployment in co location facilities adjacent to major exchanges, where every microsecond of network latency reduction translates to competitive advantage.
End to End Platform Delivery
From market data ingestion through order execution to post trade reporting, we deliver complete trading platforms, not isolated components that need to be stitched together.
