Ok, buddy, I sorta see your point. In your example, it seems that mark-to-market works against me (selling chicken); is it some kind of regulation or just a “rule”, like supply and demand?

It seems sort of artificial, or against common sense – that is, the “market” tells me that I should only have available to sell that amount of chickens that history says I can sell, but reality/common sense tells me that you shouldn’t sell chickens in front of a busy, discount chicken restaurant.
