fbtf docs

fbtf is a Node-first, ESM-only TypeScript library for deterministic historical backtests and live paper trading runtimes.

Use these docs to understand the runtime model, the public API, and the config-first CLI workflow.

The project stays intentionally small. The goal is not to simulate every possible market behavior or hide the runtime behind a giant framework. The goal is to give you a clean, explicit model that is easy to reason about when strategies get more serious.

Start here

• Getting started
• Core concepts
• Runtime flow
• API overview
• Data and markets
• Results and diagnostics
• Experiments and CLI

Principles

• one runtime model for backtest and paper mode
• deterministic, bar-driven execution
• small root API with explicit subpath utilities
• adapter-based integrations instead of provider lock-in

How to read these docs

• Start with Getting started if you want a concrete first run.
• Read Core concepts and Runtime flow if you want the mental model.
• Use API overview and the reference pages when you already know the shape you need.
• Use Experiments and CLI when you want repeatable local runs driven by config files.
