EA Developer. FX history since 2014. EA history since 2018. Kindle publication in 2021. Won 3rd place at King of EA 2022 hosted by AvaTrade. Having not achieved results despite many years of discretionary trading, I sought to establish rules from a statistical perspective and learned how to create EAs. Also, past experiences of various failures and a habit of verifying information led to successful outcomes; leveraging these, I develop EAs with a clear philosophy and policy. ■ Philosophy: To support all people in choosing a way of life more aligned with their true calling through a healthy and sincere system ■ EA Development Policy: Backtesting measured from before 2007 ／ Use **standard spread for evaluation during measurement ／ Use historical data via TDS ／ More than 1000 trades (with 1 position) ／ 1 signal = 1 position ／ Overall recovery factor (net profit ÷ maximum drawdown) of 10 or more ／ No averaging down or Martingale ／ Implement TP and SL ／ Do not camouflage performance with compounding, multiple positions simultaneously, or gaps in mobile screen history
