    If todayPos.Instrument.InstrumentTypeID <> TYPE_FIXEDINCOME OrElse todayPos.Instrument Is Nothing Then
    Continue For
    End If

    It works so much better if you do the defensive bit before the OrElse...

      Oh wait, that guy forgot another null check:

      If todayPos.Instrument.InstrumentTypeID <> TYPE_FIXEDINCOME OrElse todayPos.Instrument Is Nothing OrElse todayPos Is Nothing Then
      Continue For
      End If

      Hope that helps with the ugly "reference not set to an object" exception you faced. :-\
