For those that has small investment, I highly recommended getting the free trade from Robinhood. It's a app for mobile trading only at the moment, but in early 2018 they will release a web base which you can trade via PC.
UPDATE :Robinhood is now active for PC users
I have personally use it for two years, so far so good. Go here for more details.
