2.4. GetPositions
GetPositions method returns an array of "Position" structures. This array corresponds directly to the Positions window in Streamster. Each Position structure in the returned array contains one position with its associated fields as displayed in Streamster. GetPositions returns an array of Position structures which contain only fields available in Streamster - if you wish to retrieve any fields not currently shown in Streamster's Positions window, you have to add them by clicking the Columns button.
Sample - PHP: The following sample retrieves all positions and lists them.
<?php
$api = new SoapClient ("http://127.0.0.1:8018/service.wsdl",
array('features' => SOAP_SINGLE_ELEMENT_ARRAYS));
$r = $api -> GetPositions();
if(property_exists($r, "Position")) {
foreach($r -> Position as $n => $PositionInfo) {
echo "\tPosition " . $n . "\n";
foreach($PositionInfo as $field => $value) {
echo "\t\tField: " . $field . " = " . $value . "\n";
}
}
}
?>
Sample - Visual Basic: The following sample retrieves all positions and lists them.
Dim api As StreamsterApi = New StreamsterApi
Dim ap As Position()
Dim p As Position
ap = api.GetPositions()
For Each p In ap
Console.WriteLine("")
Console.WriteLine("Position:")
Console.WriteLine("PositionID: " & p.PositionID)
Console.WriteLine("Desk: " & p.Desk)
Console.WriteLine("Instrument: " & p.Instrument)
Console.WriteLine("Side: " & p.Side)
Console.WriteLine("OpenPrice: " & p.OpenPrice)
Console.WriteLine("Currency: " & p.Currency)
Console.WriteLine("Quantity: " & p.Quantity)
Console.WriteLine("Points: " & p.Points)
Console.WriteLine("Profit: " & p.Profit)
Console.WriteLine("ExitStopLoss: " & p.ExitStopLoss)
Console.WriteLine("ExitTarget: " & p.ExitTarget)
Console.WriteLine("Entered: " & p.Entered)
Console.WriteLine("Exited: " & p.Exited)
Console.WriteLine("Status: " & p.Status)
Console.WriteLine("Text: " & p.Text)
Console.WriteLine("ClosePrice: " & p.ClosePrice)
Console.WriteLine("Interest: " & p.Interest)
