1The first thing you have to do is choose an online stock broker.
There are many to choose from like Robinhood, Charles Schwab, Fidelity, and Ameritrade. A lot of online brokers are now offering commission-free trading, which is great! Before, depending on the online stock broker, it used to cost anywhere between $4.95 to $6.95 every time you bought or sold a stock, which added up quickly. So before you select the stock broker, look into the details of the fess that they may charge.
