If you hit $0 Avail. funds for trading, your account will go into a margin call and Ameritrade will force you to sell positions or deposit money. I'm going to assume your Account Balance isn't -8.1k because you would have hit a margin call long before your account went negative unless this all happened overnight.
Sadly, these peaceful animals may not survive into the next century. Ape conservationists say time is running out, as there are only about 720 mountain gorillas left in the world, and the majority of gorilla populations are plummeting.
The endangered mountain gorillas (Gorilla beringei beringei) are never and will never will be found in any zoo in the whole world as they canât survive while caged. These apes can only be seen in Africa; Uganda, Democratic Republic of Congo (DRC) and Rwanda.
