LS Securities (078020.KS) has launched the API Investment Strategy Center, an integrated website designed to expand retail access to algorithmic trading (automated rule-based investing). The platform consolidates the brokerage's xingAPI, a Windows-based proprietary professional trading interface, and web-based OpenAPI services in one place. Its ChatGPT-linked generative AI assistant can turn an investor's written strategy into working trading code, while a transaction specification document helps train the system on LS Securities' API structure. To support users with limited coding experience, the center offers sample code in languages including Python, a three-stage beginner guide and simulated trading for testing strategies before real-money deployment. It also provides WebSocket-based real-time quotes and a Strategy Studio for applying technical indicators such as the golden cross and Bollinger Bands. A launch promotion runs through the end of the year, offering commission discounts on domestic stock trades to investors who open accounts remotely and register for OpenAPI.
