I've been thinking of opening a ROTH IRA account for a while now and finally did it on Wednesday.
Motif Investing is the broker that I opened my IRA account. The minimum opening account balance is only $300.
It is a good broker where you are allowed to purchase up to 30 stocks one time at a price of $9.
I went with them because of this great pricing. It allowed me to diversify my portfolio at a very cheap price.
