[amibroker] IB controller question

[wei_laser]

Hi, 

 I am new here. Just trying IB controller, but how come everytime when place 
the order out to my paper acount, it places several times? I just tried the 
sample from IB controller 1.3.0 read me:

ibc = GetTradingInterface("IB");
if( ibc.IsConnected() ) // check if connection to IB was successfull
{
   OrderID=ibc.PlaceOrder("MSFT", "BUY", 100, "MKT", 0, 0, "DAY", True ); // 
} 

Could anybody help? Thanks.
