Buy Wall

A “buy wall” occurs when a large limit order at a specific price level is placed to purchase a large amount of an asset. When a buy wall is erected, the result is frequently a tightly held price equilibrium that does not fall below the target price. Buy and sell walls can both be used to manipulate market prices. Buy walls can be used to prop up the price of an asset to make it appear healthier than it is, with the goal of manipulating the behavior of retail investors.
