The aim is the "Holy Grail." Even knowing it is impossible, I deliberately yearn for the Holy Grail and strive to bring the impossible a little closer to possible—so I build logic and tools with that mindset. From childhood I created games with BASIC, and after graduating from a Japanese high school I moved to the United States on my own. I studied mathematics and art in university, and architecture in graduate school, and I was awarded the National Mathematics Chapter in mathematics. Currently, while working as a consultant for a major global IT company, I have been seriously involved in stocks since 2002 and FX since 2012. After early significant losses, I thoroughly adopted the principles of "lose small," "maintain discipline," and "verify first," and by using the triangular currency parity concept and risk management I succeeded in increasing my retirement allowance at my previous foreign company. I purchased a coveted condominium in Tokyo for my family, designed a full renovation myself, and completed it last summer, living with my family. I turned the triad currency parity method that proved effective in practice into a generalizable tool, which is the "Intervention Aftermath" series. By looking for traces of arbitrage intervention left by HFT and interbank activity, I implemented logic that targets only the distorted “aftermath” phase—short phases where after time lag or overshoot, a convergence (gap narrowing) tends to occur. I codified the past mistakes of my former self (mini-Me)—chart monitoring fatigue, jumping in, just verifying and being satisfied, working part-time with no time—into a prescription, and my development policy is to "only release tools that I myself would seriously want to use."
