Hello Austin, welcome to the forum, at 21 and just started trading again, how did your last go at trading go?
I am a buy and hold sort of investor, so I can't probably help with your trading journey, many on the forum are technical traders so use the search function and find some great info.
One thing I have learnt, is there is no sure fired way of winning in the market, it is a case of choosing an investment path that suits your personality.
So in reality a degree in economics doesn't in itself make a trader, the market isn't learnt from a book, it is interpreted from experience because the market is driven by emotional factors and the investor is also.
Just my thoughts.
