IB's commission structure is great if you trade frequently, but not for the average "sock money away in index ETFs for retirement" kind of investor.

  How so? Assuming you're buying say $3k of SPY each month, you'll pay $1/month. Why is that not great?

    If you have less than $100k in your account then you must spend at least $10/mo on commissions. If you fail to spend $10/mo then they'll just charge you the difference as an activity fee.

      That's true but I suspect most retirement accounts are worth the $100k.
