That’s such a loaded question It really depends on your Trading purpose (day/swing/invest/dividends), how much finances you’re using and how you handle your emotions when red occurs.
I’d suggest writing another post asking that questions in more depth (ie: i want to be a day trader/i want to be a long term investor), and get a pen and paper to hand as you’ll get loads of good advice which you can consider if its any use to you.
write a log of your trading activity, and learn from your mistakes is essential.
Researching your company interest, and keeping up to date with pending news will likely help you to understand how the stock performs with catalyst such as earning, good news, bad news.
finding Trading forums, discords, fb etc, so you are within a trading community i have found useful, as it can be lonely stuck at a desk for most of the day if day trading, and using informative charts such as trading view and finviz are a great help…
I had to stop myself writing an essay, as too much information can also be overwhelming.
All the best
