I decided that I want to start day trading, do I just start off with like a service like td ameritrade or is there something better? Does it provide software to trade with or do I do it manually via web? Does software provide a way to auto sell once it reaches a certain level? Also if software doesnt provide a way to autosell, is it ok to build a macro that monitors the software's controls for you. I'm lookin to invest a small amount at first, is it better to spread the money over say 5 stocks? I know this is quite high risk to jump into without knowing a whole lot, but it can be done right?
