<prompt> Human: Tomorrow is my 18th birthday and my sister called me and told me to set up an account with a brokerage such as TD Ameritrade thats what she uses. But from what Ive seen, they require an account minimum and a fee every time a trade is made. I know nothing about any of this and I would greatly appreciate some tips on how to start and maybe even some guidelines on what stocks to buy.EDIT The overwhelming consensus is to use Robinhood. Ive never even heard of it before today. So it looks like this was the right place to turn! Thanks guysgals!  <response>: Check out Robinhood and Boglehead InvestingEnjoy!
