应该随时可以改吧，帮你顶顶

实在是太笨了，来请教一下。我在fidelity里开了个roth IRA的帐户，选的是每个月放钱的那种，这样的话，我能每个月自己买fund或stock吗/还是要等这一年放满了才能买/而且我能再自己转点钱进去放到去年的名额上吗？谢谢！

Answers to both are yes.

Last year's limit is $4000.

You can open up an account online.  I opened one not long ago (not ROTH IRA though).

Here is the link to open up an account from Fidelity:
