### Comment:
I would have assumed that a company named Ameri**trade** would be the broker while TD would have been the bank.

### REPLY:
You’re correct, Ameritrade was a broker and TD was a bank. TD Bank owned a brokerage named TD Waterhouse. TD Bank sold TD Waterhouse to Ameritrade, who then renamed itself to TD Ameritrade to reflect the merger of Ameritrade and TD Waterhouse. 
  
 You can select to have your buying power held in a TD Bank account, and the two companies are affiliated in several ways (branding being the most obvious), but they are still two entirely separate, individual companies.

### END.
