I have worked for many years as a GUI designer at a major electronics manufacturer. I never struggled to make ends meet, but I always had the desire for a richer and freer life. That desire opened the door to unexpected hell. I initially started in FX out of mild curiosity. However, due to a lack of knowledge at the beginning and rushing for results, I experienced significant losses. I tried many products, but I did not achieve the expected results, and I was painfully reminded of how few methods have reproducible results. That failure became a turning point, and I began to study seriously. I worked on design tasks by day and continued validating past charts by night. Leveraging the observational skills, information organization abilities, and pattern recognition I had developed through my career, I analyzed vast amounts of data over several years. What became clear in the process was that the market repeats itself in “waves,” a simple yet certain regularity. Based on this discovery, I began developing signal indicators to objectively grasp the waves of the market. After tens of thousands of trials and refinements, I insisted on a non-repaint design and continued development until it functioned stably even in real trading environments. As a result, I was able to complete a highly reproducible indicator that delivers the same signals under the same conditions no matter who uses it. Using this indicator, my own trading became stable. I recovered the capital I had lost from the profits I accumulated, and gradually began to achieve results stable enough to surpass a salaried employee’s income. Eventually, I left my company and chose to become a full-time trader and run my own business. What struck me through this experience was that “not accidental wins, but trading based on reproducibility and scientific basis is the salvation.” That’s why I want to deliver truly reproducible trading methods to people who are迷い and suffering just as I once was. The arrow signal indicator I developed is by no means a “magic tool that makes you rich easily.” However, because it is an indicator I established through millions of debts, countless failures, and deep despair, I believe I can deliver the real thing to people who are迷い and suffering in FX.
