## 2026-07-28 v1.0.1

- Added the `spbt_day` notebook for interactive single-day backtest result
  analysis, including SQLite result file selection from the local data
  directory.
- Added selector-pair loading and dense ranking by `mr_score.final`, preserving
  rows with invalid score JSON for inspection.
- Added theoretical return calculation for ranked pairs from
  `trading_instructions`, including reusable helper functions and tests.
- Added a Plotly histogram for visual analysis of total theoretical return by
  pair.
- Moved notebook support code into reusable `scripts/spbt_day.py` helpers.
- Adjusted notebook table outputs to show all relevant rows and reduce
  redundant intermediate displays.
- Added an alphabetically sorted pair selector for individual pair analysis.
- Added selected-pair theoretical execution tables and aligned TheoRet
  calculations with target-delta trade generation.
- Added per-asset `strength` values to selected-pair theoretical execution
  tables.
- Corrected theoretical execution size to use
  `10000 * strength / reference_price`.
- Removed `:USD` quote suffixes from displayed pair names in notebook tables,
  chart hovers, and the pair selector dropdown while preserving full internal
  pair keys for calculations.
- Added `num_trades` to pair TheoRet summaries, counting asset-level theoretical
  trades from effective `TARGET` and `CLOSE` instructions.
- Added sortable interactive grids for the pair TheoRet and selected-pair
  theoretical execution tables.
- Styled interactive dataframe grids with black text on white backgrounds for
  readability across notebook themes.
- Added a selected-pair Plotly chart that overlays theoretical BUY/SELL
  executions on relative 1-minute market close data for both instruments.
- Anchored the selected-pair market chart at trading-day midnight and normalized
  relative prices to each instrument's close at that timestamp.
- Added a `min_pctg_change` threshold for ranked pair TheoRet calculations to
  skip small target-strength changes after a position is acquired.
- Added a notebook input field for the minimum TARGET strength-change threshold.

## 2026-07-25 v0.0.9

  environments.
