100 is the starting point. A reading of 120 means +20% from the first shared close; 80 means −20%. The lines compare performance, not token prices or share ownership.
GeckoTerminal USD closes: SPACEHOOD/SPCX on Uniswap v4 and SPCX/USDG on Uniswap v3. 24H and 7D use hourly candles; 30D uses daily candles. Only shared timestamps are used; unfinished candles are excluded. The provider carries the last close through empty intervals. Gaps in returned data stay visible. Pool prices can differ from other venues.
Period difference = SPACEHOOD return minus SPCX return, in percentage points. It is not a correlation coefficient. Retrieval time is separate from the last completed close.
