Korea Investment Securities said on April 3 it will provide additional open-source code related to the development of its own trading systems using its OpenAPI.

Korea Investment Securities is providing free OpenAPI-based sample code and a backtesting function through GitHub, an open-source platform for developers.

The newly added investment strategy creation function is designed to let users set buy and sell criteria using various technical indicators, including moving averages and momentum.

It also provides basic strategy examples, allowing users with limited development experience to refer to them when building algorithmic trading strategies.

The backtesting function supports checking a strategy’s rate of return, loss periods and asset changes based on past market data.

Users can run strategies using the provided Python code examples and review the stability and characteristics of actual investment strategies.

AI-linked functions have also been strengthened. If users enter conditions in natural language in AI-based development environments such as Claude Code and Cursor, the system can generate them in code form or continue into data retrieval and testing tasks.

Kim Kwan-sik (김관식), head of the Digital Innovation Division at Korea Investment Securities, said, "As interest in algorithmic trading and AI-based development environments grows, we plan to continue expanding related technologies and open source so that anyone can easily and precisely create their own investment strategies."
