Order Aggressiveness

Order aggressiveness measures the degree to which a trader is willing to pay a premium to ensure immediate execution of an order. Highly aggressive orders consume existing liquidity by crossing the spread to trade at the best available ask or bid price.

Conversely, passive orders sit in the order book waiting for a counterparty to initiate the trade. In high-frequency trading and cryptocurrency markets, aggressive orders are primary drivers of price discovery and volatility.

They signal urgency and conviction, often leading to rapid price movement when the order book is thin. Aggressive market orders prioritize speed over price, while aggressive limit orders are placed at or beyond the current best price to ensure a fill.

Understanding this metric helps participants gauge short-term momentum and potential exhaustion in a market trend.
