Using Sentiment Analysis in Algo Trading
Traditional trading methods mainly focus on numbers like volume, price patterns, and past data. But they often overlook human psychology.
Financial markets don't just move because of numbers. Breaking news, public opinions, and human behavior also play big roles.
Sentiment analysis lets traders add qualitative data to their quantitative models. This gives them a deeper understanding of the market's mood and helps predict price changes.
By using sentiment analysis, traders can see if the market is too optimistic, leading to lots of buying. It can also predict market drops by tracking negative sentiment.
Including sentiment analysis in trading models helps traders take advantage of psychology-driven behaviors. This can lead to smarter decisions and better profits.
