This monorepo contains multiple packages for building automated trading bots, including the famous trading-signals library and its documentation website. These packages provide TypeScript implementations of technical indicators, trading strategies, and data transformation utilities for algorithmic trading.
The trading-signals library is tested in production and trusted by hundreds of projects worldwide.
This project uses Lerna for managing the monorepo with independent versioning. Execute npm test to run tests across all packages. Launch an interactive demo with npm run docs.
| Package | Description |
|---|---|
| @typedtrader/exchange | Unified exchange interface providing interoperability across different brokers (e.g., Alpaca). Offers type-safe data transformation utilities and a streamlined API for integrating multiple exchanges and brokers into your trading applications. |
| @typedtrader/messaging | End-to-end encrypted messaging interface for controlling personal trading bots remotely via XMTP protocol. Enables secure command execution and real-time trading bot interaction. |
| trading-signals | Technical indicators (SMA, EMA, RSI, MACD, ...) for algorithmic trading with streaming updates, replace mode, lazy evaluation, and memory efficiency. Can be added to your own trading apps or strategies. |
| trading-signals-docs | Documentation and showcase website built with Next.js, featuring interactive demos and examples of all indicators. See every indicator in action before you code. |
| trading-strategies | Trading strategy implementations that combine technical indicators into actionable advices. Can be used to build your own strategies for backtesting and real-time trading. |
At the foundation, trading-signals provides technical indicators like SMA, EMA, RSI, and Bollinger Bands. The trading-strategies package builds on top of these indicators to form actionable trading advice. @typedtrader/exchange abstracts away broker differences behind a unified interface, so strategies can run against any supported exchange. Finally, @typedtrader/messaging ties it all together into a chatbot that lets you control your trading bot remotely through encrypted messages.
