You can find an armory full of knowledge about the stock market on Youtube, here are my favorite people who have taught me how to trade. I am also not affiliated with them in anyway they just have a wealth of knowledge that will help you learn to trade or become a better trader.

Rayner Teo's videos on technical analysis are broken down step by step and great for beginners. I cant recommend him enough, and suggest that if you are new to the trading world you start here. 

Roensch Capital is a regular poster of stock market news and catalyst who usually makes new videos several times a week.

FrankNez Has great videos on youtube and also his own blog https://franknez.com/ for all things market related.

Brad Finn and In the money have videos that are more about trading options, so if you already know the stock market but you are interested in getting into derivatives this is where I would start.  

There are many others on Youtube that are worth looking into but these are my go to when its time to study up. So watch their videos until you can repeat everything they are saying and then head into the world of trading. We all found ourselves here, interested in the world of finance for one reason or another so make sure that you are equipped with the knowledge to succeed.
