A Sell Wall in the stock market refers to a large number of sell orders for a particular security that have been placed at a certain price level. This creates a "wall" of resistance, as there are more shares being offered for sale than there are buyers willing to purchase them at that price.A sell wall can indicate that there may be a significant amount of downward pressure on the stock's price, as the sellers are willing to accept a lower price than the current market value. However, it should be noted that the presence of a sell wall does not necessarily mean that the stock's price will drop - it could also mean that a large holder of the stock is looking to sell a large position, but is doing so gradually in order to avoid pushing down the stock price.
