NaviOpen Source. Indicators. Strategies.

Navi is a Rust-style scripting language for trading charts. Complete pipeline — parser → compiler → VM, with LSP and VS Code support.

Full Pipeline

Complete implementation from parsing to execution — parser, semantic analysis, compiler with optimization passes, and a bar-by-bar virtual machine.

Supports Navi syntax including indicators, strategies, libraries, custom types, enums, methods, and the standard library.

Use from Rust, C/C++, or through the Language Server Protocol. Includes a VS Code extension and a web playground.

Ships with prelude and stdlib implementations — ta, math, str, array, map, matrix, and more — all written in Navi itself.

Full LSP with 20+ capabilities including diagnostics, completions, hover, go-to-definition, rename, semantic tokens, and inlay hints.

Actively developed and open to contributions. Add tests, implement features, or improve diagnostics.
