1. Best advice from someone who's been there done that.I got a solid tip you might not read in a book. No matter how much money you have...be sure your first account is no more $10k...$5k might be even better.
Starting out completely green never having any exposure to financial markets with zero guidance, a $100k account, and big dreams was probably my worst mistake.
2. Instead of books, read some of the old threads, there are a lot of very valuable comments in those old thread.
3. My advice if you day trade is to learn how to take losses. I am an amateur retail just like you, have been practicing paper day trading (real time sim) for over a year now and still not ready to go live.
