Brokers commit a wide variery of fraud and schemes, other than those mentioned specifically   on this site:

  Other types of fraud that are more rare include Illegal Accounts. A broker is not permitted to place customer's check or money intended for transactions involving securities into his own account, regardless of the amount of money or the length of time involved. Mishandling customer funds, such as money intended for insurance product or putting the money into the broker's personal account, is a serious violation and could result in prosecution by state or federal criminal agencies.

  Brokers also may not create ficticious, park money in another person's account or create false accounts in a misleading fashion.

If a broker tells a client to buy or sell a security based on a insider information (information not publicly available), the broker may have committed securities fraud. Your broker could be liable for any losses you have sustained due to insider information.

If you believe you have been victimized by some type of investor or broker fraud, you should consult a legal expert.
