They seem to work okay when I want to trade in the same direction as the radar I'm holding (because I can use your buy max option), but if I want to buy max in the opposite direction, it essentially freezes up on me as soon as I type "max" as my quantity. I have to backspace the "max" out and leave the quantity blank before it will take me to an advance trader page to make my trade.
The other problem is that this doesn't happen all of the time. It can fix itself and work, but it's very inconsistent. For example, I tried to make trades on 3 stocks about 15 minutes ago and they would not work (it wasn't working last night, either), but I just checked and it seemed to be okay at the moment. I haven't rebooted my computer or closed/reopened my browser in that time, so...???
