An observed baseline, not a fabricated daily close
The requested window is measured backward from the latest historical observation. The baseline is the most recent observation at or before that target. If the available history is shorter, the earliest observation is used and the shortened coverage is disclosed. The chart retains actual timestamp spacing. This matters when comparing a mature network with a recently covered chain: identical window controls do not guarantee identical available history.
Distinguish momentum from the path taken
Imagine a hypothetical series beginning at $400 million, rising to $600 million, falling to $300 million and finishing at $500 million. The endpoint change is positive 25%, but the observed maximum drawdown is negative 50%, measured from $600 million to $300 million. Both figures are useful. The first summarizes the endpoints; the second reveals a contraction that the endpoint comparison would otherwise conceal.
What could explain a change
Treat the result as a starting point for checking protocol composition, asset prices and changes in coverage. A rise in USD TVL does not by itself identify new deposits, and a decline does not prove withdrawals. Historical endpoint definitions can also differ from current headline totals. Use protocol history to investigate components and compare multiple observation windows before drawing a narrative. The latest historical date and browser receipt time serve different purposes: one dates the measurement, while the other records when this page received it.
