TVL (Total Value Locked) displays the dollar value of all tokens locked in this pair. The TLV is initially displayed as a value on the left side of the top pair page box, with a percentage indicating its change over the past 24 hours. However, you can look at the TVL of the pair as a graph. To do this, select the Liquidity display mode in the upper right part of the chart. Also, you can switch between chart display modes: by hours (H) and by days (D) for more convenient tracking of TVL changes.
