"Spoofy" orders (large orders placed by entities to create a false impression of market demand or supply) can influence the market & create artificial price movements.
Basic supply & demand model:
Price = f(Demand, Supply)
Manipulators (whales) might create an inflated demand 'Demand∗' by placing large buy orders that give the impression of high demand.
Price = f(Demand∗,Supply)
A derivative of this situation might look at the rate of change of price with respect to changes in demand..
