In forex trading, relying solely on what you see can be a limiting approach that may lead to biased or incomplete analysis. It's important to consider multiple sources of information and perspectives, such as fundamental analysis, technical analysis, market sentiment, and news events, to form a well-rounded view of the market. Additionally, traders should avoid letting their emotions or biases influence their decisions and should base them on objective criteria and risk management strategies. Trading based on what you want can lead to unrealistic expectations, greed, and impulsive behavior, which can result in losses. Therefore, it's important to approach trading with a disciplined and objective mindset, and to continuously learn and adapt to changing market conditions.
