title: Automatically execute an excel macro on a cell changed by a real-time add-in
body: <p>I have an Excel add-in (Bloomberg) which streams real-time prices into a spreadsheet. I need to add a column which contains the last time a price was updated. I've tried to do this with the worksheet change event, but this doesn't seem to get fired by the changes (I assume something to do with it being a real-time update).</p>
  
  <p>The requirement is the same as the question below, but the solutions do not apply since the events do not fire in this case.</p>
