Data sources and refresh
| Data | Source | Refresh |

| Completed trades across tracked Sleeper leagues | Tracked Sleeper dynasty leagues | Several nights a week; new leagues are added on a rolling basis |
| List prices | Public dynasty value charts | Daily |
| Player rankings, tiers and pick values (Rankings & Tiers) | Stats Guy Fantasy, trade-derived values per league format; tiers, movement and the TE-premium lens are computed here | Daily |

Values shown for a trade are always the prices on the date the trade completed, not today’s, so old trades are judged fairly.
Nothing changes in Sleeper except the actions you trigger yourself: saving a lineup, placing a claim, sending or answering an offer, or an auto-sub you armed.
