Barter

Barter core is a Rust framework for building high-performance live-trading, paper-trading and back-testing systems.

• Fast: Written in native Rust. Minimal allocations. Data-oriented state management system with direct index lookups.
• Robust: Strongly typed. Thread safe. Extensive test coverage.
• Customisable: Plug and play Strategy and RiskManager components that facilitates most trading strategies (MarketMaking, StatArb, HFT, etc.).
• Scalable: Multithreaded architecture with modular design. Leverages Tokio for I/O. Memory efficient data structures.

Overview

Barter core is a Rust framework for building professional grade live-trading, paper-trading and back-testing systems. The central Engine facilitates executing on many exchanges simultaneously, and offers the flexibility to run most types of trading strategies. It allows turning algorithmic order generation on/off and can action Commands issued from external processes (eg/ CloseAllPositions, OpenOrders, CancelOrders, etc.)

At a high-level, it provides a few major components:

• Engine with plug and play Strategy and RiskManager components.
• Centralised cache friendly EngineState management with O(1) constant lookups using indexed data structures.
• Strategy interfaces for customising Engine behavior (AlgoStrategy, ClosePositionsStrategy, OnDisconnectStrategy, etc.).
• RiskManager interface for defining custom risk logic which checking generated algorithmic orders.
• Event-driven system that allows for Commands to be issued from external processes (eg/ CloseAllPositions, OpenOrders, CancelOrders, etc.), as well as turning algorithmic trading on/off.
• Comprehensive statistics package that provides a summary of key performance metrics (PnL, Sharpe, Sortino, Drawdown, etc.).
