Seeing this reminds me of the time when quantitative trading was just gaining popularity. Back then, the promotional language was the same: make money while lying down, earn over ten thousand a day, achieve financial freedom. As a result, 95% of people lost their principal, and the remaining 5% are the ones who truly understand strategies, can adjust parameters, and can interpret backtesting data. The core issue is not that the tools are difficult to use, but that most people got the problem wrong from the very beginning. They thought they had bought a money-making tool, but what they actually bought was a leverage that amplifies their judgment.
