Even trading professionals fail and have losses in trading. The volatility of the market is unpredictable and not all analysis is accurate. We can't always rely on professionals because no one could predict the prices accurately with consistently. Applying the basics during confusion would be better than seeking for expert's opinion, especially during this bearish season.
professional traders, expert traders that will not be a guarantee that you will not get a loss, especially when the bearish season comes. but the difference is only in the losses that are obtained if a professional trader the losses that can be obtained will not exceed the specified limit. but a beginner sometimes the losses they get exceed the limit of almost 90%.
and in terms of profit, it is also different because professional traders use detailed analysis and novice traders use analysis as best they can without detailed knowledge.
but it's all down to luck
Basically, skills must be needed in daily trading not only for a professional but they can prevent a very large risk because they have set management in trading and of course a beginner and a professional will be different in acting so this will not be the same even though following some suggestions and the material he was given.
I think trading is not just luck, but they analyze with very precise timing, meaning that every time you enter or sell you will know the time that has been set, even though only a few percent are made in that profit, so skills are very important for professionals and beginners.
