Hello Conrad,
I agree that selling the entire batch would be the way to go (ideally). I was talking in terms of a mechanical hands off approach.
I do, however, disagree with your assertion re: MIA. I do not want to belabor the point (mostly becuase I do not have the time to run any simulations). Let's just say that the buying and selling does not have to be linear and leave it at that for now.
Regards,
Harlan
