Although EA trading can bring stable profits, setting up an account to practice your trading instincts during your free time is also a good choice. After all, if a small investment is lost, it's not too painful, and if it earns, it's just pocket money, haha. Why choose a 4-hour chart period? Because the larger the time frame, the better the stability, making it suitable for those who prefer not to constantly monitor their trades. If you're interested in day trading, of course, I'd recommend looking at 1-hour charts.
