You know, trading strategies are the backbone of how any trader approaches the market. Whether you're into day trading or future trading, a good strategy gives you structure and a framework to make informed decisions.
I agree, that the shared trading strategies of many successful traders help you think how important it was. But the question is why some traders have never been successful even following experts or successful traders. Maybe you are right that it was the backbone of trading but so many factors affect the end result of our trades - emotions and behaviors. Perhaps, these things cause major losses for many traders and even those having deep knowledge of trading but if we have been influenced by our emotions and bad behaviors, we ain't go far but end shortly.
Trading strategies and insights will always be helpful most particularly to novice traders. They need to see and hear it most often so that their motivation to trade and be successful on it will stay high. However, being a trader is not only concern with knowledge and development of skills and strategies, being patient and being in controlled of emotions also contribute a bigger outcome in trading. Without these, trading seems to end up like gambling wherein losses and mistakes will always be inevitable.
