When is market equilibrium established? What does it indicate?

Market equilibrium can only exist when the demand for a particular product is equal to supply. This indicates that sellers will be able to sell all the products, and all buyers who are ready to buy the product for the amount offered by them will be able to purchase it. It turns out that sellers will get the highest possible profit. If the equilibrium is violated, then either the profit will be smaller, or simply the entire product will not be sold on the market.
