What problem does it solve? Setting up the Futu OpenD gateway and matching Python SDK involves manual downloads, platform-specific installers, version checks, and dependency conflicts. This Skill automates the entire setup so users can connect to the Futu OpenAPI without manual installation steps. ## Core Features & Use Cases - Cross-platform automated installation: Detects the operating system (Windows, macOS, CentOS, Ubuntu), downloads the correct GUI installer, and runs platform-specific install scripts. - Version detection and upgrade: Compares the locally installed OpenD version against the latest release, skips redundant installs, and verifies downloaded package versions before installing. - SDK and dependency management: Automatically installs or upgrades the futu-api Python SDK plus backtrader, matplotlib, pandas, and numpy for backtesting workflows. - Use Case: A quant developer on a new Mac asks to set up the Futu API environment; the Skill downloads the latest OpenD DMG, installs the GUI app, upgrades futu-api, and installs analysis libraries in one flow. ## Quick Start Install Futu OpenD and upgrade the futu-api SDK on my machine, downloading the installer to my desktop.
