Database coverageEnded histories count.
Ended histories count.
Missing data stays missing.
The broader library contains 680 Binance USDT spot pairs. Each study defines its own eligible universe.
Different questions use different sets
| Research view | Coverage rule |
|---|---|
| Study 01 | Daily top 100 eligible pairs by trailing 30-day quote volume; includes ended histories; excludes tokenized stocks; reused tickers separated. |
| TIA chart search | All 680 stored pair files; 688 separate asset runs; mature, complete 30/60/90-day windows. |
| TIA context | 237 chart/lead-up matches; 111 with usable OI context; zeros or missing archives unavailable. |
| Market map | One dated top-volume universe snapshot; not the full historical catalogue. |
| Coin directory | All 680 histories as searchable rows ›; 118 map/research members have dedicated pages. Dates are specific to each exchange pair. |
What is absent
We do not have every global token, every exchange, centralized-exchange account records, or a complete historical order book. Spot trade counts are not unique people. OI coverage is narrower than price coverage, especially around older or renamed contracts.
Including ended histories reduces survivor selection, but it does not eliminate exchange-listing selection or all missing-data bias. The website is a set of saved snapshots without scheduled nightly refresh.
