Justin Gu 1e7766754e style: ruff format tests/unit/test_a_share_extensions.py 
修复 GitHub Actions 中 ruff format --check 的格式化失败。
 2026-07-03 01:30:40 +08:00
Justin Gu 133c208510 release: v1.16.3 — 修复 market-stat 全市场涨跌统计家数偏小10倍 
通达信统计指数 880005/880006 的计数类字段返回真实家数的 1/10，
get_market_stat 未做缩放还原，导致 up/down/total/limit_up 等系统性偏小 10 倍。
对 6 个计数字段统一 round(field * 10)，成交额/量/市值不动。
重写 test_get_market_stat_mapping 覆盖还原逻辑。761 单测全绿。

GitHub 155328df8b release: v1.16.2 — 三轮审计质量加固（B6.9→A7.9） 
经三轮代码审计后的综合质量加固版本，覆盖协议核心层、数据正确性、
错误处理、测试真实度与可维护性。761 单测全绿（+58），ruff/mypy 全过。

主要修复：
- 离线 .day 写入原子化（fsync + _repair_tail + 读取校验，CQS 守住）
- 回测止损前视偏差（延迟下一根开盘 + 跳空保护）
- VWAP 权重索引 / bar_time fail-fast / 绩效除零保护
- 闭包绑定 / 路径穿越 / naive datetime 跨时区 / ruff UP038

重构：
- 抽 AsyncHeartbeatMixin 收敛 4 处心跳副本（12→1）
- 统一 _RETRY_DELAYS 退避序列 / scanner 失败可观测性

新增 5 个测试文件 + 公共 API 类型契约，CI 加 Windows 矩阵 +
trusted publishing 签名 + 锁文件。

GitHub bc83ffa4ac fix(tick_charts): 多日分时图 minutes>=1440 报 ValueError (Issue #10) 2026-07-01 16:22:57 +08:00
GitHub 615994ad72 feat(kline): 分钟级K线时间戳可选bar_time对齐Tushare (Discussion #7) 
通达信协议用bar开始时间打时间戳（5min线上午最后一根标11:25、下午第一根标13:00；午休11:30-13:00无bar），而Tushare/同花顺/聚宽用bar结束时间（标11:30/13:05）。新增bar_time参数让用户一键切换，避免自行+5分钟偏移。

- 全部3条K线路径覆盖：A股get_security_bars/get_index_bars、扩展行情get_instrument_bars、MAC get_stock_kline（含同步+异步、get_stock_kline_with_indicators）

- CLI kline新增--bar-time {start,end}选项；Web /bars、/bars/index新增bar_time查询参数

- bar_time=start（默认）保持完全向后兼容；bar_time=end仅对分钟级周期（1/5/15/30/60min）生效，自动按周期时长右移并处理跨小时/跨日边界

- 协议解码层零改动，偏移作为纯展示语义在client层后处理，单一工具函数_apply_bar_time_align_df/_apply_bar_time_align_bars复用于全部路径

- 新增27个单元测试（test_codec_datetime.py偏移逻辑 + test_kline_bar_time.py三路径覆盖），全量700单测通过

- bump 版本号至 1.16.0

Justin Gu 77104a32e3 fix(ci): mypy python_version 3.10 → 3.12 修复 numpy stub 语法错误 
根因：CI 的 mypy job 在 Python 3.13 下运行，安装的 numpy 2.x stub
使用 PEP 695 type 语句（3.12+ 语法），但 pyproject.toml 的
python_version="3.10" 让 mypy 按 3.10 语义解析，报
'Type statement is only supported in Python 3.12 and greater'。

修复：
- python_version 提升到 3.12（CI mypy job 实际跑 3.13，开发目标版本对齐）
- mypy/ruff 同步排除 gitignored 的 exchange_margin.py 本地脚本
- 顺带修复 market.py / test_screen.py 的 ruff format 漂移

Justin Gu f36e2d6a6c feat(screen): v1.15.0 — 强势股排名 + 修复证券类型识别与名称分批查询 
新增：强势股排名（screen strength）
- 全市场按 5/20/60 日涨幅加权合成强势分，纯离线扫描
- 三种预设：steady(稳健)/breakout(妖股)/balanced(均衡)
- CLI: easy-tdx screen strength --preset steady --top 50 --table
- Web API: GET /api/v1/market/strength
- 支持自定义权重、成交额过滤、并发扫描

修复：
- _detect_security_type 代码段不全，ETF/基金/科创板/逆回购被误判为 A 股
- screen strength/rank 名称补齐超 80 只时末尾被丢弃（分批查询）

GitHubandClaude c54071e85e release: v1.14.1 — 高级回测 ExecutionModel 路径 3 个真实数据兼容 Bug 修复 
- datetime 类型分歧（致命）：Trade.datetime 转 int 与 PortfolioTracker 的 Timestamp key 失配，TWAP/VWAP/Limit 路径交易全部静默丢失、权益曲线恒定、收益归零
- volume 列名分歧：回测认 volume 而真实行情为 vol，滑点 volume 恒 0 退化百分比模式，VWAP 退化为等权
- date/datetime 列名分歧：日线返回 date 列引擎要 datetime，run() 入口由 date 派生下游无感兼容
新增 3 个回归测试（均红灯验证）。650 单测通过，backtest 模块 ruff + mypy strict 清洁。

Justin Gu 5fc398255d fix(types): 修复 CI mypy strict + ruff format 失败 
mypy (13 errors → 0):
- portfolio/optimizer: register_optimizer 返回类型改为 Callable 装饰器签名
  (原标注 type[WeightOptimizer] 导致 4 个子类 Too many arguments)
- factor/engine: _datetime_to_int 用 isinstance 收窄替代 object→int 强转
- factor/analysis: 删多余 type:ignore（改由 mypy override 统一处理 scipy）
- backtest/orders, execution: np.sqrt 表达式用 float() 包裹消除 no-any-return
- MyTT.pyi: MACD 签名删除错误的 LOW/HIGH 参数（与 MyTT.py 实际签名对齐）
- pyproject: 新增 scipy mypy override (ignore_missing_imports)

ruff format: 8 个 test 文件格式化

验证: 564 passed, mypy 192 文件零错误, ruff check/format 全绿

Justin Gu be41746aa9 fix(backtest): _find_bar_index 用 to_numpy().argmax() 取真实位置 
idxmax() 返回 index label，后续 iloc[] 按位置取行；当 df.index 非默认
RangeIndex 时 label != position，撮合会取错 K 线。两处分支统一改为位置索引。

Justin Gu 095c88f735 fix(transport): ping 容错 TdxConnectionError，避免单台服务器拖垮测速 
ping_host 仅 except OSError，但握手期 _recv_exact_sock 抛的 TdxConnectionError
继承自 TdxError(Exception) 而非 OSError，逃出捕获后经 ping_all 的 fut.result()
重新抛出，导致非交易时间服务器 accept 后立即 FIN 时整个 easy-tdx ping 崩溃。
- ping_host: except (OSError, TdxConnectionError)，对齐 docstring 返回 None
- ping_all: fut.result() 加 try/except 防御层，单 host 失败只跳过不崩
- 新增 2 例回归测试

Justin Gu 0e74752701 fix(web): validate market/category input — support lowercase, reject invalid with 400 
Root cause: _market_from_str/_market/_category in routers used bare
MarketEnum[key]/Market[key] without .upper() or try/except, so
lowercase or invalid values (sz, ZZZ) threw uncaught KeyError → 500.

Fix: extract shared convert.py with market_from_str/category_from_str
that do .upper() + ValueError on invalid input.  All 4 routers updated.
4 regression tests added for case-insensitive and invalid input.

Justin Gu 92edc189bb feat: realtime event-driven market data push framework 
- Add EventBus for async publish/subscribe market events
- Add MarketEvent dataclass with tick/bar/signal/error types
- Add RealtimeStrategy base class with on_tick/on_bar callbacks
- Add emit_signal() for strategy-to-engine signal publishing
- Support per-symbol and global subscriptions
- API skeleton: transport-level subscription TBD
- Add 10 tests covering events, bus, and strategy
 2026-06-11 02:34:00 +08:00
Justin Gu 9c39ad054d feat: multi-stock portfolio backtest engine 
- Add PortfolioBacktestEngine for shared-capital multi-stock backtesting
- Support equal allocation mode (total_cash / N per stock)
- Individual BacktestEngine per stock with allocated capital
- Aggregate performance via capital-weighted returns
- Add StockData, PortfolioResult data classes
- Add 4 tests: basic run, equal allocation, empty stocks, serialization
 2026-06-11 02:31:43 +08:00
Justin Gu f4dc28c5d2 feat: add append_klines for incremental chanlun analysis 
- Store previous DataFrame in ChanlunAnalyser after process_klines
- Add append_klines(df_new) to concatenate and recompute
- Handles datetime deduplication automatically
- Raises RuntimeError if called before initial process_klines
- Add 2 tests: append + recompute, error without init
 2026-06-11 02:25:42 +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
 2026-06-11 02:17:52 +08:00
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
 2026-06-11 02:09:10 +08:00
Justin Gu af005d9fe4 feat: auto-bridge chanlun analysis into backtest strategies 
- Add chanlun_level param to BacktestEngine constructor
- When set, auto-create ChanlunAnalyser and compute ChanlunResult
- Manual chanlun_result in run() takes priority over auto-compute
- Update Strategy.chanlun type to Any (accepts ChanlunResult or dict)
- Add 2 tests: auto-bridge and manual override priority
 2026-06-11 01:56:59 +08:00
Justin Gu 815b3ddf7c feat: implement stop-loss/take-profit execution in backtest engine 
- Track SL/TP conditions from BUY signals in _generate_signals loop
- Check active conditions against each bar's high/low price range
- Auto-generate SELL signal at trigger price when condition is met
- Modify OrderSimulator to respect signal.price for direct execution
  (previously signal.price was stored but never used in execution)
- SL/TP activates on bar AFTER BUY signal (consistent with next_open)
- Stop-loss checked before take-profit (conservative for holder)
- Add 4 tests: SL trigger, TP trigger, no-trigger, priority over manual sell
 2026-06-11 01:53:11 +08:00
Justin Gu 06b2617ebc fix: CI coverage enforcement, real avg_holding_days, vectorize _datetime_to_int 
- Add --cov and --cov-fail-under=50 to CI pytest command
- Replace hardcoded avg_holding_days=5.0 with FIFO-based calculation
  from actual trade datetime pairs (handles int and Timestamp types)
- Vectorize _datetime_to_int using pd.to_datetime().strftime()
  instead of Python for-loop (~100-200x faster on large arrays)
- Add 3 new test cases: weighted holding days, no datetime fallback,
  only-buys edge case
