Self-introduction: I work for a communications software company. When I was in junior high school, I encountered software development (programming; initially BASIC) and was struck by it. Software is something that, once taught, can continue to do things for you without ever making mistakes, forever in your place—that seemed so reassuring to me! At university I studied parallel computing and numerical simulation, and after joining a company I gained experience mainly in system design, as well as in software engineering, project management, performance evaluation, and quality assurance. Indicator development: In FX, I’m not good at sticking to charts, so I began developing indicators and signal tools from the perspective of making chart checking as easy, quick, and reliable as possible, in order to recognize the trading environment easily and accurately, which started my efforts to organize my investment setup. The indicators I am listing are ones I personally feel “I can’t live without,” and I would like to publish those. → I started listing them from September 2023. The number of items listed is still small, but I plan to keep adding more!
