Latent volume as DS explains it is similar to classic models of static supply and demand curves in microeconomics, where supply is proportional to price while demand is inversely proportional to price. This is where the fundies are trying to buy low and sell high.
I say static because these curves can also shift, in which case the situation is reversed. Price is directly proportional to the SHIFT in the demand curve and indirectly proportional to the SHIFT in the supply curve. This is where the trend followers come in. Panic sellers dump more as price falls, and bandwagon buyers pile on as price rises.
This second phenomenon doesn't seem to be reflected in your model DS, unless it's just supposed to be the red tech orders? |
