The Active Value Locked (AVL) describes the share of the Uniswap liquiidty that is being actively used to facilitate trades. It helps measure capital efficiency on Uniswap.

The mean AVL is determined by aggregating the amount of liquidity within the price ticks of a specific pool that fall within the designated price range.

This metric presents the total of the AVL for a given fee tier on Uniswap V3. For each traded token-pair Uniswap allows for pools with four different trading fees: 0.01%, 0.05%, 0.3%, 1%.

To improve its accuracy, adjustments have been made by eliminating token reserves that showed signs of token price manipulation.
