kay-ou

Kay-ou is an independent software publisher whose single public project, SimTradeDesk, targets quantitative traders who want a fully offline workstation for building, back-testing and paper-trading strategies before pushing them live through Chinese brokerage APIs. The tool combines a lightweight desktop shell with an embedded Python runtime, real-time market data bridge, SQLite trade logger and one-click deployment hooks for CTP, Esunny and Tongshi gateways, giving retail algorithm developers a sandbox that never leaves the local machine. Typical workflows include importing tick or minute-bar CSV files, vectorised or event-driven back-tests, visual equity curves, instantaneous forward-walk optimisation and replay-based simulated order matching; once validated, the same codebase is promoted to the broker’s production server without further adaptation. Because the stack is delivered as a portable Windows executable, users can keep strategies, source code and account credentials on an encrypted USB drive, satisfying compliance officers at small prop shops and university trading labs that forbid cloud exposure. SimTradeDesk is available for free on get.nero.com; the site supplies the latest build through the winget repository, supports batch installation alongside other research utilities and always fetches the most recent release signed by the original GitHub maintainer.
