One row per underlying; contracts inside the filter are stored together (one row per contract per day). The filter is set when adding and can only be widened by adding data again. Few underlyings, so no search, filters or pagination.

Annotations: Dataset detail is a full page (no drawer); clicking a dataset name on Data (02) opens it, the breadcrumb Data goes back. Sample: Equity · US · Daily, the largest dataset (308 symbols). ① Header: dataset name (Asset class · Market · Resolution) and its Status (02 ⑨). ② Stats: Symbols, Range, Bars, Size in DuckDB, default Source, Last updated, Auto-update, Available timeframes. ③ Auto-update Switch, off by default; same setting as the list. Source can be changed under Edit (02 ⑪). ④ Available timeframes: what backtests can use from this dataset, built from its resolution (Daily: 1d, 1w; an Hour dataset shows 1h · 2h · 4h; Minute shows 1m · 5m · 15m · 30m). ⑤ Actions: Update now (new bars up to today), Fill n gaps (refetches only the missing ranges of all symbols; disabled when there are none), + Add symbols (opens Add data with Source, Asset class, Market and Resolution fixed), Remove dataset (text, error colour; confirmation, variant). ⑥ Coverage: one aggregate bar for the whole dataset over its range: green = every symbol has data, orange = a gap where one or more symbols are missing (drawn at least 5 px wide), labelled with how many symbols are missing; hover shows dates and count (shown on the first). Symbols listed later (SNOW, ARM) count as covered from their first bar. Gaps also come from ranges skipped when adding data (02b ⑧). ⑦ Symbols table, sorted by Gaps (descending) here; every column sorts (MUI TableSortLabel). ⑧ Search by symbol and filter chips All / With gaps with counts. ⑨ Checkbox column with select-all in the header (indeterminate when some are checked); with rows checked a selection bar shows n selected with Fill gaps and Remove (removes those symbols from the dataset after a confirmation). Pagination 50 rows per page (1–50 of 308). ⑩ Row expand (▾): that symbol's own coverage bar and its gap list with exact dates, plus Fill gaps for BA. ⑪ Option datasets (variant) list underlyings instead, with the filter used (≤ 60 DTE · ±20% of spot) and rows; the rest of the page is the same. ⑫ Remove: Cancel / Remove (contained, error colour); the data is deleted and a Snackbar confirms. Bots and strategies are not changed; a later backtest that needs the data shows Missing data (02 ⑬).
