Today’s robot gave us a psychological drama during the testing phase. The morning market was a bit fierce, with floating losses once exceeding over ten thousand dollars. To be honest, it was a bit suffocating to watch. But this guy stubbornly turned the situation around before the close, ultimately locking in a profit of over $500, completing a reversal from black to red.

Looking back, this kind of volatility actually validates our original intention when designing the quantitative strategy. We don’t pursue big gains every day, nor do we indulge in the fantasy of getting rich overnight—our core approach is steady, consistent, and accumulative returns. That’s the way to survive long-term. What can really drive people crazy is often this kind of daily, continuous, predictable profit process.

Another feeling is that the robot’s execution ability and psychological quality are indeed unmatched. If a human trader were to operate for more than six hours of intense trading, they would either be mentally exhausted or start making frequent mistakes. But once the strategy is set, this machine can execute step by step without emotional fluctuations or subjective judgment errors. This might be the biggest advantage of quantitative trading—using discipline to conquer human nature.
