Yes, TD Ameritrade is turning off access to QT as of 9/1. NOTE: Medved Trader is NOT impacted by this and will continue to work with TD Ameritrade, so you really should switch to that: http://www.medvedtrader.com
As for @JK, though we encourage clients to get a paid subscription, it is not a requirement. You can use MT for free even after the first month as long as you are OK with the restritions: http://www.medvedtrader.com/restrictions
Also, there are ways to get MT free - with TK accounts, or if trading 8+ times per month with Tradier.
