Installation guide
Up and running in minutes
Three dependencies, one command. Here is everything you need before you run your first analysis.
Install Claude Code
trading-OS runs inside Claude Code — Anthropic's official CLI. If you already have it, skip ahead.
npm install -g @anthropic-ai/claude-code
Requires Node.js 18 or later. You can also download the Claude desktop app, which includes Claude Code. A Claude Pro or Max subscription is required to use Claude Code.
Verify
claude --version
Install Python 3
trading-OS uses Python scripts for market data fetching. Python 3.9 or later is required.
Or download the installer from python.org/downloads. Python 3 is often already installed on macOS and Linux.
Verify
python3 --version
Install Just
just is the command runner that exposes every trading-OS entry point as a single short command. It is the only interface you need to learn.
Cargo and pre-built binaries are also available at github.com/casey/just.
Verify
just --version
Install trading-OS
After purchase you will receive an email with a zip file. Unzip it into any directory, open Claude Code there, and you are done.
unzip trading-os.zip -d trading-os cd trading-os claude .
No additional configuration is needed. Free market data via yfinance works out of the box. You can add premium data sources later by editing one line in the config file.
Run your first analysis
Inside Claude Code, type one command. Seven analysts run in parallel, the debate fires, the risk committee weighs in, and you get a clear verdict.
