We are developing analytical tools to read the “ distortions” that are hard to see with just a single currency pair, by analyzing multiple price relationships. The goal is not merely to forecast correctly, but to narrow the market conditions to watch and make it easier to decide which situations to pass on. We shape only what we can genuinely want to use ourselves, after extensive verification. From childhood, I programmed games in BASIC, and after graduating from high school in Japan I moved to the United States alone. At university I studied mathematics and art, and in graduate school I studied architecture, receiving the National Mathematics Award in the field of mathematics. Currently, while working as a business consultant, I have been actively involved in stocks since 2002 and FX since 2012. In the early days I experienced substantial losses, but through that process I deeply felt the importance of the principles of “small losses,” “discipline,” and “verification first.” Since then I have built my own analysis and improvements centered on the ideas of triangular currency parity and risk management. I even fulfilled my long-cherished dream of buying a condominium in Tokyo and designing and completing a full renovation myself. In both work and investment, I value understanding the structure, designing it, and bringing it into shape. The ideas honed in those real-world experiences have been generalized into a more reproducible form in the “Intervention Aftermath” series. Focusing on price distortions, time lags, and short-term convergence phases that are likely to occur after overshoots caused by influences such as HFT and interbank markets, it is designed to enable efficient observation, screening, and judgment of those specific moments only. Chart-monitoring fatigue, impulsive entries, ending only after verification, and not having enough time due to being a part-time trader—these past mistakes and worries have become the starting point for the logic design itself. The development policy has remained consistent: “Only bring to the world tools that I myself genuinely want to use.” Rather than flashy features, the aim is to slightly improve actual decision-making, reduce unnecessary trades, and lead to more convincing buy/sell decisions.
