Built for quantitative rigour

Most backtesting tools operate at L1. StratLabs goes deeper — simulating the full market microstructure so your results are actually meaningful.

📊
Level 3 order book simulation
Replay full order book depth with realistic fill logic. Understand exactly where your orders execute — not just what the mid-price was.
⚡
Slippage & market impact
Model realistic slippage as a function of order size, spread, and available liquidity. No more optimistic fills that vanish in live trading.
🔗
Multi-venue execution
Simulate order routing across multiple exchanges simultaneously. Account for latency, fee tiers, and cross-venue liquidity aggregation.
📈
Strategy analytics
Comprehensive performance reporting — Sharpe, Sortino, drawdown analysis, turnover, and execution cost breakdown per trade.
🛠
Python & C++ API
Native SDKs for Python and C++. Define strategies programmatically with full access to the simulation environment at every tick.
🔒
Institutional grade
Deterministic, reproducible results. Audit trails on every backtest run. Built for teams who treat strategy research as an engineering discipline.
⏳ In development

The engine is being built

StratLabs is currently in active development. We're building something that doesn't cut corners on execution realism. When it's ready, it'll be worth the wait.
