It is strange that no one mentions the destination of the order when you discuss the commision carges?
I have an account at E*trade, PreferredTrade, closed one at IB recently, and in the works to opening ThinkorSwim account.
But the one thing I have learned is that the commission charges are based on where the order is sent and how many trades you make. e.g. PT offers different commish charges.
PT offers a $9.75 flat rate (or a $15.00 trade anywhere you want). But the catch is your order is routed to a market making firm (NITE). PT surely receives pmt for this.
If you are a hyper active trader I believe you can get .01/share at most firms. Usually this means more than 100 trades/mo. or higher (some 500!) for some firms.
Other firms route to ISLD whenever they can because ISLD pays for adding liqudity and makes the broker look good with instant modifies and cancels. Any firms that charges more than $10 for ISLD trades is robing you. In my IB account I noticed I was always popping into the ISLD book.
When your order goes to ARCA it is routed outside of ARCA and ARCA has to pay for fees and direct links, so you order costs more.
The bottom line is you should know where your order is going and what you are paying for.
For destination ECNs it should be cheap.
For MM is should be very cheap.
For ECNs with full features and smart routing it should be more.
Plus, now there is AMEX Nasdaq on monday morning Aug 12. Will your trades be able to execute there if AMEX is at the NBBO?
