Market forces determine the direction of free markets and prices for goods and services, including who can get the resources and who will provide the resources.
The main forces that drive markets are supply and demand.
Efficient markets will find a balance between demand and supply naturally without any intervention. It is also known as ‘invisible hand’.
No matter the selling price of a good and service is set higher or lower than the equilibrium price, or the market changed, the market forces will push the selling price back to the equilibrium level (market clearing price) and clear the market.
