Following people's signals in forex trading can be a useful strategy for beginners or those who lack the expertise or time to analyze the market themselves. However, relying solely on signals without understanding the underlying market dynamics and developing one's trading skills can be risky and unsustainable in the long run. It's important to have a basic understanding of technical and fundamental analysis and to use signals as a complementary tool rather than a primary source of information. Additionally, traders should be aware of the risks associated with signal providers, such as false signals, market manipulation, or unethical practices. Ultimately, to achieve sustainable success in forex trading, traders need to develop their own trading style, risk management strategies, and continuously improve their knowledge and skills.
