Request Portfolio Updates

Note here that the IB API associates 3 callbacks with reqAccountUpdates()

However, TWS.Events.PORTFOLIOUPDATE is linked only to EWrapper:updatePortfolio() callback.

For events associated with updateAccountValue() see TWSAccountUpdatesExample.

% request account updates [*USE YOUR IB ACCOUNT NUMBER HERE*]
session.eClientSocket.reqAccountUpdates(true,'DU207406');

Process PortfolioUpdate events

Print out updates to the screen
