From buyers to creators — A classroom for Gold EA development

朝日奈りさ

From "EA is something you buy and use" to "something you make yourself." This series is a serialization for those who want to create a dedicated EA for Gold (XAUUSD) from scratch by themselves. From idea generation, logic design, and MQL5 implementation to backtesting, forward testing, and improvements—this series will have active gold EA developers (Ryū Shōkin, CHAOS_GOLD_LISKOFF_MT5, and Kinmyaku AI developers) explain every step of EA development. Even if you have no coding experience, it's okay. Start by learning "what the EA is doing on the chart," and gradually move toward being able to "create" it. This is not a get-rich-quick story. The core is steady validation and a mindset to avoid overfitting (curve fitting). The specific contents of particular products (such as parameter values) will not be disclosed; instead, we share a universal "way of thinking" that can be applied to any EA. It is practical content for those who buy and use EA as well as those who want to evaluate EA critically.
