Market Order Fill

Definition ∞ A market order fill occurs when a buy or sell order is executed immediately at the best available price in the market. Unlike limit orders, market orders prioritize speed of execution over a specific price. The entire order is typically filled, though the execution price might differ slightly from the displayed price. This method ensures quick entry or exit from a position.
Context ∞ In cryptocurrency trading, a market order fill is a common execution method for traders seeking immediate action, especially in fast-moving markets. The speed of a market order fill is often a key performance indicator for digital asset exchanges. However, during periods of low liquidity or high volatility, market orders can experience price discrepancies, impacting the final cost for the trader.
