Developer Tools

LeetBacktest Engine

A vectorized, multi-asset back-testing framework written in Rust with Python and TypeScript bindings. Supports tick-level and bar-level simulation, custom slippage models, and deterministic replay. Processes ten years of minute-bar data for a 500-instrument universe in under 90 seconds on commodity hardware.

🧰

Strategy SDK

A batteries-included Python SDK for defining, testing, and deploying trading strategies. Handles signal generation, position sizing, order construction, and execution routing through a declarative API. Write your alpha logic; we handle the plumbing.

🚀

LeetDeploy (Managed Cloud)

One-command deployment of containerized strategies to a managed Kubernetes cluster with built-in monitoring, alerting, and log aggregation. Supports canary rollouts, automatic rollback on drawdown thresholds, and live parameter tuning via a web console or CLI.

🔌

LeetViz Dashboards

Real-time strategy monitoring dashboards built on a lightweight, self-hostable web stack. PnL curves, drawdown heat maps, fill analysis, and factor exposure charts update tick-by-tick with sub-second latency.
