Can someone explain what is a sentiment? How do you define it? or What is a sentiment, and why does i

Short answer: Sentiment = emotion + opinion, bundled together.

Longer answer: It’s how *intense* or *direction* (pos/neg) an attitude is. "Market sentiment" is just whether traders are hype or scared.

And yep, it’s subjective AF. Try VADER Sentiment (free tool) to see how it scores text. Super handy for social media stuff.
