Wall of Sell Orders Manipulation is when a manipulator places a large number of sell orders at a specific price level, creating a virtual 'wall' that prevents the price of an asset from breaking through that level. These huge orders may intimidate other traders who find it difficult to break through that price limit.

However, once the manipulators have purchased enough tokens at the lower price, they withdraw the sell orders, allowing the price to rise quickly. This tactic is often used by market makers and high-frequency traders to accumulate asset chips at low prices.
