I have to believe AMTD has a number of elite traders that get special attention. Maybe streamers & command centers for traders that make several trades a day. At one time I got special attention for 3 accounts with large deposits- was # 3 on the profit list with AMTD. But when they got so many MM and doing machine (trade triggers) trading I backed off.
Rarely does a company shot themselves for no reason. CocaCola was one and they quickly recanted their New Coke mistake. AMTD stock headed down from the last day of Streamer Suite. Lots of traders thinking about leaving. Ameritrade has no clue what they have done and for what?
