Aggressor Volume
Aggressor volume represents the volume of trades initiated by market participants who take liquidity from the order book by using market orders. These traders are considered "aggressive" because they do not wait for the price to come to them; instead, they cross the spread to execute their trade immediately.
Tracking aggressor volume is a key component of volume profile analysis, as it reveals which side of the market is currently in control. A sustained increase in buy-side aggressor volume suggests strong upward momentum, while high sell-side aggressor volume indicates bearish sentiment.
This metric is vital for understanding short-term price trends and the effectiveness of support and resistance levels. It provides a clear view of real-time buying and selling pressure.
