Justin Gu c9ed57e66d fix: parallel scan pickle bug — pass strategy file path instead of class to child processes 2026-06-11 04:24:09 +08:00
Justin Gu 15cc7680c4 release: v1.9.7 — CLI全量集成（workers/cache/chanlun-level/portfolio/multi-level）+ bugfix 2026-06-11 03:57:48 +08:00
Justin Gu ec8d21b7e2 feat: incremental scanning with mtime-based cache 
- Add cache_file param to SignalScanner for persistent scan cache
- Cache stores {filepath: {mtime, result}} as JSON
- On rescan, skip files with unchanged mtime (reuse cached results)
- Files with changed mtime are rescanned and cache updated
- Add 3 tests: cache reuse, no-cache full scan, cache invalidation

Justin Gu b7e0f17842 feat: concurrent scanning with ProcessPoolExecutor 
- Add workers param to SignalScanner.scan() (default=0 for serial)
- workers=2+ uses ProcessPoolExecutor for parallel .day file processing
- Extract _scan_one_file as top-level function for pickle compatibility
- Results identical between serial and parallel modes
- Add 4 tests with synthetic .day file fixtures

Justin Gu a3d6d93122 feat: strategy screener - scan all stocks by signal, rank by backtest performance (v1.9.2) 
- Add 'screen' CLI command group with 'scan' and 'rank' subcommands
- scan: offline signal scanning from local .day files, zero network IO
- rank: backtest ranking of scanned signals by sharpe/drawdown/etc
- Two-step workflow: scan outputs JSON, rank reads JSON and evaluates
- Support --universe (all/sh/sz/custom file), --sort, --names
- Support pipe mode: scan ... | rank --from - --table
- New module: src/easy_tdx/screen/{scanner,ranker,cli}.py
- 20 unit tests (offline, no network required)
