Input message queries server for the trading price of a corporation
The input message defined by the above WSDL definition carries a ticker symbol for a publicly-listed
corporation. It has the following form:
<soap:Body
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<tns:TradePriceRequest>
<tns:tickerSymbol>stockTickerSymbol</tns:tickerSymbol>
</tns:TradePriceRequest>
</soap:Body>
Output message provides trading price (if successful) or a status indicator (if not successful)
If the query succeeds (that is, if a share quotation can be obtained for the given ticker symbol), the output
message from the server carries the price per share for the requested corporation. It has the following
form:
<soap:Body
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<tns:TradePrice>
<tns:price>pricePerShare</tns:price>
</tns:TradePrice>
</soap:Body>
If the query fails (for example because there is no known listing for the given ticker symbol), the output
message carries a status indicator. It has the following general form (with whitespace added for clarity):
<soap:Body
xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
