re: Setting up automatic investing contributions in trading account

I’ve got a brokerage account set up with Vanguard and have automatic deductions taken out each paycheck. I just invest mine in vanguard’s 500 Index Fund (VFIAX). I’m sure you could set up 3 separate deductions for each fund you want to invest in if it won’t let you do them all on one transaction. I’m a novice when it comes to investing and it was easy enough for me to set up.
