This is one of the most important decisions you'll make when learning about the stock market. Day trading involves making multiple trades in a day, while swing trading is when you hold your positions for days or weeks at a time.
When day trading, you'll need to be ready to make decisions quickly, as markets can move in a matter of seconds. It's best to learn about this type of trading by starting with a demo account and then moving to a live account once you're comfortable.
Swing trading allows you to take advantage of longer-term trends and could be a better approach if you don't want to be glued to your computer all day.
