EA developer. FX experience since 2014. EA experience since 2018, development experience since 2020. Kindle publication in 2021. Placed 3rd in King of EA 2022 hosted by AvaTrade. Developing for both MT4 and MT5, mainly with a single-position approach. Feeling that no amount of studying leads to results through discretion, I aimed to establish rules from a statistical perspective and learned how to build EAs. From late 2025 to 2026, I finally began to create reasonably solid EAs. Taking this opportunity to return to my初心, I revisited my philosophy and policy, added a vision, and am developing EAs while executing PDCA. ■ Philosophy: To support all people in choosing a life more aligned with their destiny through a sound and honest system ■ Vision: To make EAs an alternative to investment funds ■ EA development policy: ・Backtests are measured for at least 10 years (MT4) ・Historical data use both Dukascopy data from TDS and MT5 real tick data ・MT4 development spread set to an in-house standard ・At least 1,000 trades per EA (target) ・1 signal per position ・Annualized recovery factor of 1.00 or higher (target) ・No martingale or averaging down ・TP/SL placement
