Further, a total lack of understanding on a trading platforms performance with your "conclusion that because an account balance is updated immediately/quickly that the data must be delayed !!!!

No, I did not say it was because the account data was updated quickly. I said that because you are not paying extra for real time data. Last time I got into this debate with someone, I called thier broker, and they told me that to have REAL TIME streaming chart data, you had to pay a subscription fee. Only streaming *Delayed* data was free.
My broker is the same way. For free, you get streaming data that is delayed for 10 to 15 minutes. For $70.00 you get real time streaming charts. In addition ICE futures charges $65.00 for thier real time chart data which my broker passes along without any markup if I want (and I do want).
For your broker to pay the exchanges for the data feed, AND only charge you $8-11 round turn, will cause him to lose money if you are not a very frequent trader. Brokerages are not in the business to lose money. It makes no logical sense to do that.
