All notable changes to this project are documented in this file.
|
|
|
|
## Unreleased
|
|
|
|
No unreleased changes yet.
|
|
|
|
## 2026-07-30 v1.0.4
|
|
|
|
- Updated notebook and Panel analysis for the SP Quant result database schema,
|
|
including explicit `trading_instructions` columns for action, assets,
|
|
scaled disequilibrium, and beta.
|
|
- Changed selected-pair market charts to read from the `market` table and kept
|
|
legacy packed instruction JSON support for older result databases.
|
|
- Added `scaled_disequilibrium` and `beta` to selected-pair theoretical
|
|
execution displays.
|
|
- Improved VS Code notebook usability with the `jupyter_bokeh` dependency,
|
|
direct Plotly figure rendering, and a dropdown Analyze control for individual
|
|
pair selection.
|
|
- Made the Panel app use the dark theme by default and reduced the sidebar
|
|
width from 430 px to 215 px with responsive sidebar controls.
|
|
- Expanded tests and notebook verification coverage for the new database schema
|
|
and Panel layout defaults.
|
|
|
|
## 2026-07-29 v1.0.3
|
|
|
|
- Removed invalid fixed sizing mode from Panel Tabulator grids to avoid Bokeh
|
|
layout warnings while preserving compact table layout.
|
|
- Changed the Panel Calculate action to refresh the result-file list before
|
|
loading data and removed the standalone Panel Refresh button.
|
|
|
|
## 2026-07-29 v1.0.2
|
|
|
|
- Added a Panel application for single-day SPBT result analysis with result-file
|
|
selection, minimum TARGET-change input, pair TheoRet table, pair selector,
|
|
selected-pair execution table, and market/trade chart.
|
|
- Added a launcher script for the Panel application.
|
|
- Changed notebook and Panel pair analysis to use per-row Analyze actions from
|
|
the Pair TheoRet grid, deferring selected-pair calculations until clicked.
|
|
- Adjusted Panel sizing so key controls use compact widths and Pair TheoRet uses
|
|
content width with vertical scrolling instead of full-width paginated layout.
|
|
- Added a FastListTemplate shell to the Panel application for sidebar controls
|
|
and configurable app color accents.
|
|
- Made Plotly chart panes use all available horizontal space.
|
|
|
|
## 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.
|
|
|
|

|
|

|
|
- Updated ignore rules for local data, generated results, caches, and local
|
|
environments.
|
|
- Documented unreleased changelog handling and release push behavior.
|
|
