I currently have a Brokerage account and an IRA with Fidelity. I'm planning on purchasing two Vanguard funds ($75 fee for each fund) and trading securities ($20 a trade). Should I open an account with Vanguard and move everything over? Should I open an account with a discount broker, move my brokerage account and keep my IRA with Fidelity? Should I just keep everything with Fidelity? Thanks for your help.
