Behavioral economists believe that all price changes are influenced by the psychology of traders. Therefore, emotions can be the main driver of prices. Therefore, happiness and excitement, greed, optimism, pessimism, stress, worry, trust, etc. are the most important key factors in currency pricing. On the other hand, in fact**, market sentiment** shows the average of all sentiments at a given moment.
You must have heard what Warren Buffett said: buy when others are afraid and sell when others are greedy. A correct understanding of market sentiments can provide a clearer path for trading.
