Large buy orders (buy walls) at a specific price level can signal strong support, suggesting that the price may not fall below this point easily. Similarly, large sell orders (sell walls) at higher price levels indicate strong resistance, making it harder for the price to rise. If these large orders are absorbed or moved, it could lead to a breakout or breakdown. For example, if a buy wall is absorbed, it may indicate strong buying pressure, potentially pushing prices higher. Monitoring these order book dynamics helps traders anticipate price movements and key levels of support and resistance.
