Impact of Market Orders

Market orders are instructions to buy or sell an asset immediately at the best available current price, which directly consumes the liquidity provided by existing limit orders. Because they prioritize speed over price, market orders have the most significant impact on price discovery and slippage.

In thin markets, a large market order can exhaust the available liquidity at the best bid or ask, forcing the execution price to move to the next available levels in the order book. This immediate consumption of liquidity makes market orders a primary driver of short-term volatility and a major source of cost for traders.

Understanding how market orders interact with the order book is fundamental to predicting price movement and managing execution risk in any derivative or crypto asset strategy.
