Nautilus Trader is a production-grade, Rust-native trading engine designed for multi-asset, multi-venue trading systems. It features a deterministic event-driven architecture that enables research-to-live parity, allowing strategies to be developed, backtested, and deployed live with consistent behavior. The system comprises a core Rust engine with Python bindings for strategy development, modular adapters for over 20 exchanges (including Binance, Coinbase, Kraken, and DeFi platforms), and infrastructure for backtesting, live trading, risk management, and analysis. Key components include a CLI tool for system management, a LiveNode for production trading, and a BacktestNode for historical strategy evaluation. The architecture emphasizes modularity, with separate crates for model, core, execution, trading, risk, analysis, persistence, serialization, and exchange-specific adapters, all communicating via an actor-based message bus.
This repository is a production-oriented Go client library for the Binance cryptocurrency exchange, covering spot, margin, USDS-M futures, coin-margined delivery futures, options, portfolio margin, and related products. The code in v2/ exposes fluent builder-style services for REST endpoints and WebSocket streams, with clients such as NewClient, NewFuturesClient, NewDeliveryClient, NewOptionsClient, and portfolio-specific clients. The library is consumed by trading bots and exchange-integration applications; it is not a data analysis or research project, though it provides market-data access primitives for klines, tickers, order books, funding rates, and historical trades.
OsEngine is a comprehensive, multi-exchange algorithmic trading platform for desktop (WPF/WinForms hybrid). It provides data downloading (OsData), backtesting (OsTester), walk-forward optimization (OsOptimizer), and live trading (OsTrader) with support for 30+ exchange connectors (MOEX, Binance, Bybit, OKX, Interactive Brokers, etc.). The platform includes a built-in technical indicator library (100+ indicators), a trading robot framework with attribute-based registration, and an MCP (Model Context Protocol) API for external AI/automation control. The architecture is modular: separate executables for different modes, a common server abstraction layer, and a consistent parameter system for bots and indicators. While the codebase is large and well-organized, it suffers from significant duplication across exchange connector entity classes and some copy-paste logic in trading robots. The UI mixes WPF and Windows Forms, and some patterns are legacy. Overall, it is a production-grade algorithmic trading platform with strong engineering practices and a rich feature set.
Gabagool is a Python-based arbitrage trading bot for Polymarket's 15-minute prediction markets, with performance-critical components implemented in Rust via PyO3 extensions. The bot implements the 'Gabagool arbitrage' strategy: buying both YES and NO shares when their combined cost is less than $1.00 to guarantee profit regardless of market outcome. The architecture features a modular design separating concerns into API clients (Gamma and CLOB), trading strategy, position tracking, risk management, and persistence layers. Key components include a thread-local HTTP session manager to prevent connection pool issues, a SQLite-based persistence layer for trade and position data, and a thread-safe position tracker with expiration mechanisms. The system supports multiple operational modes including live trading, paper trading simulation, and backtesting against historical data. Recent development activity shows active maintenance with ongoing Rust integration for performance optimization.
