<p>A financial transaction system is accessible by users across a computer network, such as via a web site on the Internet. Each of the users is associated with at least one certain contract that limits their transactions by time, by equity, by number of trades, and by other parameters. Each user can request financial transactions, e.g., place trades, across the computer network while a financial transaction administrative server verifies and limits the transactions made by the user according to the particular at least one contract associated with the user.</p> |
