To address the fourth requirement in the IMEX system, you must be able to trade securities from the client Flash movie. The user will enter one or more buy/sell trades into the Flash movie, and then transmit them to the server using an XML element called TRANSACTION . Each TRANSACTION element contains one or more TRADE elements.

<TRANSACTION SESSION="rnr6f7vkj2oe14m7jkkycilb" />
<TRADE ACTION="BUY"
    TYPE="MARKET"
    SYMBOL="RICH"
    QTY="50" />
<TRADE ACTION="SELL"
    TYPE="LIMIT"
    PRICE="50.375"
    SYMBOL="POOR"
    QTY="100" />
</TRANSACTION>

To indicate whether the transaction succeeded or failed, the server replies with one of the following TRANSACTIONREPLY elements:

<TRANSACTIONREPLY STATUS="OK" />

or

<TRANSACTIONREPLY STATUS="FAILED" />
