I just created a TD Ameritrade account and downloaded the app, mostly because I want to learn more about stocks. I started with $50 in my account just to open it, but I can just as easily close it if I find out there's really no benefit to having it.
Already have a 401k and another IRA through Vanguard, so I'm not sure there's a need for it, but if I can learn some things using that app, or learn things after buying a few stocks here and there, I'm all for it! It's a cash account, not a retirement account. Thoughts?
