Watching your big losses really makes me envious, having money is great. My losses are all due to testing the system, less than 4000 yuan in 5 years. Without a solid profit-generating system as a foundation, I really don't dare to increase my investment. I've tested countless strategies, and none have passed 100 backtests. This system is all my effort, and I don't plan to invest any more funds. Since it has passed my tests, even a few dozen yuan in capital will make me rich. Everything is left to time.
