as practical matter if the price of execution really bothers you then never put a market order with this type of brokers and account
He's just trolling. The post topic is "Anyone having trouble at Ameritrade today?", about which he has nothing to add. I doubt he even has an account.
Quotes froze for a bit even after closing and reopning the site. Luckily the trades I had were thourgh IB and was just using ToS for the charting but this has happened very rarely no matter how frustrating it was today.
i use thinkorswim for charting only and it froze up twice today in the morning. So decided to call it quits today and wait till its fixed completely for tomorrows event
