Focusing on system trading of Nikkei 225 mini, I develop automated trading strategies. I have 30 years of experience dealing with the market. I started with commodity futures and have long engaged in discretionary trading, but I realized the difficulty of consistently winning based on my own judgment, so I shifted focus to rule-based automated trading. I know firsthand the strength of executing decided strategies calmly without letting emotions interfere. The most important factor in strategy development is not the win rate but the drawdown. No matter how a strategy is designed, there will always be periods of losses. Therefore, I value honestly conveying test results, including maximum drawdown and markets that are challenging, not just convenient numbers. I will provide products that can be judged by actual validation data, not flashy marketing slogans. Thank you for your continued support.
