Block Trades are trades which are executed in a master account, and then later distributed to client accounts using an allocation criterion such as account value or account available cash.  Pro and Enterprise versions licensed to operate at the Pro-4 level support distribution of block trades from a master account to other accounts.  Block trades can be allocated using the Block Trade Distribution function accessible from the Batch Ops submenu:
