GMO Strategy Language (GML) is a domain-specific language (DSL) designed for defining gold trading strategies in the Smart Gold Trading Decision Assistant ecosystem. This extension brings full language support, syntax highlighting, and backtesting capabilities directly into VS Code.

Whether you're a beginner writing your first trading rule or an experienced trader building advanced multi-condition strategies, this extension makes the process fast, comfortable, and reliable.
