One row per launch LEDGE has indexed that took zero buys, at least 72 hours after its own launch block: its pair, its creator tax, its age, its sells, and its distinct first-block buyers where that block was itself indexed.
The activity index that feeds this page only began recording curve trades recently. A launch that finished its whole life before that start has no row here at all, and its absence means it was never measured -- it does not mean the launch took a buy. The exact count of launches the index currently holds, and the oldest one among them, is printed above the table on every load.
Buys and sells are counted from indexed curve trades. A row's buy count is always zero -- that is the gate a launch has to meet to appear here at all -- and its sell count is whatever LEDGE indexed regardless. A launch older than the indexed record has a partial count, and its own row says so.
Distinct first-block buyers is absent, never zero, when that launch's own block was never indexed. Zero means the block was read and nobody bought in it.
