Holding Period

Roblox trade hold

Roblox applies a 48-hour holding period after a limited is received in a trade. Limitra calculates this from the exact received timestamp when Roblox exposes it, otherwise from when Limitra first observed the current owner holding the copy.

Limitra continuously scans every tracked limited and records each copy's holder — the timeline above grows as transfers are observed. Entries marked observed came from inventory sightings where Roblox did not expose the exact received date. Trades that happened before tracking began can't be backfilled.
