FLOX is a modular framework for building trading systems with polyglot strategy bindings and AI-friendly developer tools. Strategies run on one C++ core in Python, Node.js, Codon, or embedded JavaScript. Same strategy code goes from backtest to live without a rewrite step.
Documentation is available at flox-foundation.github.io/flox
Language bindings
| Language | Install | Docs |
|---|---|---|
| Python | pip install flox-py |
reference |
| Node.js | npm install @flox-foundation/flox |
reference |
| Codon | build from source | reference |
| JavaScript (embedded) | bundled with C++ build | reference |
| C API | libflox_capi.so |
reference |
All bindings expose the same strategy API, indicators, order books, backtesting, and data I/O. The C API is the integration point for adding support for any other language.
AI companion
flox-mcp is a Model Context Protocol server that gives AI coding agents (Cursor, Claude Code, Cline) grounded access to the FLOX surface — symbol lookups across bindings, scaffolders, indicator and backtest tools, full-text doc search.
pip install flox-mcp
See the package README for setup and the full tool list.
Connectors
Native exchange connectors (Bybit, Bitget, Hyperliquid, Polymarket) live under connectors/ and build with -DFLOX_BUILD_CONNECTORS=ON. The flag defaults to OFF so a backtest-only or research build doesn't pay the dependency cost. See the connectors README for adapter notes and the optional Polymarket Rust toolchain step.
Build options
The CMake options that gate every optional artefact (bindings, demo, tools, tests, benchmarks, connectors) are catalogued in docs/build/feature-flags.md. Defaults are OFF so a bare cmake -B build produces only the core C++ static library.
