This column is brought to you from Naraku and Kira's "EA Lab." I, who build and run EAs myself, will share daily insights in a relaxed, down-to-earth way—covering how to build EAs, how to interact with AI, how to read backtests, and how to protect capital. I’ll honestly write not only about what went well, but also about the missteps and failures. Support leader Kira also pops in from time to time. From beginners to intermediate users, I hope to provide at least one hint that makes you think, “I’ll give it a try.” ※This column is intended to provide information and is not investment advice. There is a risk of loss in EA operations. Past results do not guarantee future performance.
