Rules like “no trading on Fridays” or “never buy more than a set amount at once” become a rule file. It compares them with your trade history and sorts each trade into followed, broken, or can’t tell. Before placing an order, you can also ask, “Does this buy break my rules?” When you’re in a hurry, it skips the AI and runs only the rule engine, answering within 0.5 seconds.
Code makes every decision, and the AI explains the results in words. It does not judge whether a rule is good or bad. When a trade breaks a rule, it does not say “don’t buy.” It only states that the trade conflicts with a rule you set.
It is a Codex plugin I built for the KakaoPay Securities task in the 2026 AX Talent War. The 223 is the scope of the code tests. It has nothing to do with real investment results.
