Your observations are correct. No signal group or individual trader can generate signals with 100% accuracy, and it's important to use caution when following signals or trading based on someone else's recommendations.

It's also true that even if a signal provider has a high win rate, it's important to consider all of their signals and not just pick and choose based on a few recent results. Trading requires a long-term strategy and approach, and it's important to remain consistent in your trading approach even if you experience a few losses.

Analyzing charts and finding opportunities to enter trades can be a good approach for traders who have the time and skills to do so. However, it's important to note that trading requires a significant amount of research, analysis, and discipline to be successful. It's important to have a solid understanding of technical analysis and risk management principles, and to be prepared for potential losses.

Ultimately, the most successful traders are those who have a well-defined strategy and approach, and who are able to remain disciplined and consistent in their trading activities
