Common Challenges
We Understand High-Frequency Trading Engineering
Trading systems live and die by microseconds. The challenges we help prop shops, market makers, and quant funds work through.
Latency Budget Across the Stack
Every microsecond between market data ingest and order send matters. Optimizing it requires looking at NIC offload, kernel bypass, lock-free data structures, and CPU pinning together, not in isolation.
Market Data at Line Rate
Full-depth feeds from US equities (SIP, direct feeds), options (OPRA), and futures generate millions of messages per second. Parsing, normalization, and order book reconstruction have to keep pace without dropping packets.
Pre-Trade Risk Without Slowdown
SEC Rule 15c3-5 requires controls on every order, but adding a risk gate naively adds latency. The architectural problem is making the controls run in tens of nanoseconds, not milliseconds.
Backtest-to-Production Drift
Strategy P&L looks great in backtest, then disappoints in production. Closing the gap means replaying real exchange data through the exact production code path, not a Python notebook approximation.
What We Build
High-Frequency Trading Engineering Capabilities
Engineering capabilities for low-latency market data, execution, and pre-trade risk that hold up at line rate.
Low-Latency Trading Engines
C++ and Rust execution engines built around lock-free queues, false-sharing-aware data layouts, and CPU pinning. Targeting tick-to-trade in the low microseconds.
Market Data Infrastructure
Multicast feed handlers for FIX/FAST, ITCH, OUCH, OPRA, and direct exchange feeds. Order book reconstruction, normalization, and tick storage in kdb+ or ClickHouse.
FPGA and Kernel Bypass
Solarflare Onload, ef_vi, DPDK, and FPGA-accelerated parsers for feed handlers and pre-trade risk gates that need to run in hardware-timestamped nanoseconds.
Pre-Trade Risk and Controls
Rule 15c3-5 compliant risk gates: position limits, fat-finger checks, order-rate counters, kill switches, and credit checks built inline without blowing the latency budget.
Strategy Backtesting and Simulation
Event-driven backtest engines that replay full exchange data through the same code path that runs in production, with realistic queue position modeling and slippage from observed fills.
Co-located Deployment and Ops
Deployment at NY4, NY5, LD4, FR2, and equivalent exchange-proximity data centers, with PTP-grade timestamping, hardware latency monitoring, and automated failover.
