Market sentiment analysis is the process of evaluating the overall attitude of traders towards a particular currency pair. It involves analyzing various indicators such as news, economic data, and social media activity to determine whether the market is bullish or bearish. Traders use this analysis to make informed decisions on whether to buy or sell a currency pair. However, it's important to note that market sentiment is not always accurate and can change rapidly, so traders should use it in conjunction with other analysis tools to make informed trading decisions.
