How to get existing positions from the Broker ?

[ash29]

I am trying to see which function I should use to get my existing positions (for a particular symbol) from the Broker.

Here's a snippet of my code:

var symbol = getSymbol();
debugPrintln("This is the symbol " + symbol);
var position = new SBPosition(getSymbol());
debugPrintln("This is the position variable " + position.Size);

The position always returns as 0. Now I do not know the construction method for SBPosition (not given in any guide/help file).

Could someone who has success is getting their existing position quantity from the broker please post that snippet of code ?

Also if there is any code that directly links to interactive brokers to place 'buy' and 'sell' orders, please post that example ?
