Quote from brokerj:
lots of brokerage firms out there
I know what you're saying, but for a regular retail trader with a smallish account, there's nobody that even comes close to IB's commissions. Prior to IB, spreads and commissions must have eaten most small traders alive.
I've got a few complaints with IB, but overall I LOVE them. They have eliminated 95% of the barriers to entry for a small, part time guy like myself.
