UbuntuandCursor a243edd2d3 docs: 补依赖清单与 README
此前仓库无任何依赖声明。按 AST 扫描全部 import 后按用途切分:
requirements.txt 为核心运行时 8 个包,requirements-dev.txt 追加测试与
research/ 所需。

matplotlib / mplfinance / xgboost / scikit-learn 只出现在 ChanPY.py、
ChanLun_Classifier.py、Find_Trend.py、ChanHeng.py 这四个零引用文件中,
故不纳入清单;ChanPY.py 依赖的外部 chan.py 库本就未安装。

README 记录目录结构、启动方式、库用法、分析流程九步与数据约定,并注明
三处现存问题:web/DEPLOY_GUIDE.md 引用的 6 个部署脚本已在 7f393b9 删除、
web/README.txt 指向不存在的 web/requirements.txt、systemd unit 的端口
8123 与 config.py 默认的 8128 不一致且 gunicorn 未声明。

清单已在全新空 venv 中验证:仅装 requirements.txt 时 57 个模块可导入、
Flask 16 条路由正常;装 dev 清单后测试 24 通过。

UbuntuandCursor 206b27fe72 refactor: 以自实现指标替换 talib 与 technical 依赖
chanlun/indicators/ta.py 接口兼容 talib.abstract,实现代码实际用到的
SMA/MA/EMA/RSI/ATR/MACD/BBANDS;chanlun/pipeline/resample.py 替代
technical.util.resample_to_interval。调用点只改 import,逻辑未动。

暖机长度与平滑种子按 TA-Lib 的约定实现,差一根 K 线就会让下游所有
笔/线段/中枢整体位移。其中 MACD 需特别处理:TA-Lib 让快慢两条 EMA
在同一根 K 线出首值,因而快线的种子取 x[slow-fast:slow] 的均值,而非
从 fastperiod-1 一路递推——两者在百元价位上相差约 0.17。

BBANDS 是有意的分歧:TA-Lib 用 sumsq/n - mean² 求方差,短窗口远离零
时灾难性抵消(timeperiod=2 误差 8.7e-7),本实现用 rolling std,对 50
位精度基准误差为 0。项目实际使用的周期两者一致到 1e-10。

顺带清理 12 个文件中 16 处从未调用的 talib/technical 导入。

验证:9440 组随机对拨;真实 K 线端到端比对 add_indicators 全部 33 个
指标列,NaN 模式一致、MACD 柱符号 100% 相同;屏蔽两个包后 60 个模块
均可导入。新增 test_ta_compat.py 将输出逐 bar 钉在 TA-Lib 上,但该文件
在 TA-Lib 缺失时静默跳过,改动 ta.py 需在装有 TA-Lib 的环境复跑。

# CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
## Project Overview
缠论 (Chan Theory) technical analysis system for Freqtrade. Implements Chan Zhong Shui Chan's theory for crypto/stock trading, including fractal (分型), stroke (笔), segment (线段), pivot/center (中枢), and buy/sell point (买卖点) detection.
## Governance
- Agent 入口:`AGENTS.md`boot 顺序)· `docs/PROJECT_PROFILE.md` · `docs/AGENT_MEMORY.md` · `docs/STATE/CURRENT.md`
- ESS 文档:`docs/ECR/``docs/ENGINEERING_SPEC/``docs/TRACEABILITY.md``docs/CHANGELOG/`
- **正式引擎包**`chanlun/`strategies / web 已用 `from chanlun import ...`
- 根目录 `Chan*.py` / `TF_DF.py` 仍为 **兼容 shim**(旧脚本可用)
- 变更分级:无 ECR 不改 strategies/config;无 ADR 不改缠论算法语义
## Core Architecture
### Chan Theory Engine (`chanlun/`)
```text
chanlun/
core/ # KLU KLC BI SBI SEG ZS BIZS BSP Enum CTime
pipeline/ # orchestrator(ChanLun) + timeframe(TF_DF) + builders/
indicators/ # ChanMACD*
analysis/ # Zone Classifier Pivot Heng PY Find_Trend ...
```
Data processing pipeline (each step feeds the next):
1. **`chanlun.core.ChanKLU`** — Raw K-line unit with TA indicators and pattern recognition
2. **`chanlun.core.ChanKLC`** — Combined K-line: inclusion + fractal; `.next`/`.pre` linked list
3. **`chanlun.core.ChanBI`** — Stroke (笔)
4. **`chanlun.core.ChanSBI`** — Special stroke → SEG
5. **`chanlun.core.ChanSEG`** — Segment (线段)
6. **`chanlun.core.ChanZS`** / **`ChanBIZS`** — Centers (中枢)
7. **`chanlun.core.ChanBSP`** — Buy/Sell points
8. **`chanlun.pipeline.orchestrator.ChanLun`** — Orchestrator
9. **`chanlun.pipeline.timeframe.TF_DF`** — Timeframe facade;实现拆在 `pipeline/builders/`
### Services
- **外部 DATA_SERVICE** — 行情服务(env: `DATA_SERVICE_URL`);本仓库可不含 data_provider 源码
- **`web/`** — Flask UI`create_app()` + `api/` blueprints + `services/`;前端 `static/js/app/`。默认端口见 `web/config.py``FLASK_PORT`,常见 8128
- **`strategies/`** — Freqtrade strategies(本 ECR 不改)
- **`config/`** — Freqtrade configs(本 ECR 不改)
### Data Flow
```
Exchange / DATA_SERVICE → Freqtrade Strategy / web → ChanLun → TF_DF
→ KLU → KLC → BI → SBI → SEG → ZS → BSP
```
## Common Commands
### Freqtrade Trading
```bash
# Live trade
freqtrade trade -c ./user_data/Chan/config/<config>.json --strategy <StrategyName> --strategy-path ./user_data/Chan/strategies
# Backtest
freqtrade backtesting -c ./user_data/Chan/config/<config>.json --strategy <StrategyName> --strategy-path ./user_data/Chan/strategies --timerange=20251008-
# Download data
freqtrade download-data -c ./user_data/Chan/config/<config>.json -t 1m 1h 1d --pairs BTC/USDT:USDT --timerange=20240101-
# Hyperopt
freqtrade hyperopt --hyperopt-loss SharpeHyperOptLossDaily --spaces roi --strategy <StrategyName> --strategy-path ./user_data/Chan/strategies -c ./user_data/Chan/config/<config>.json -e 200 --timerange=20250201-20250901
# Plot
freqtrade plot-dataframe --strategy <StrategyName> --datadir user_data/data/binance -c ./user_data/Chan/config/<config>.json --timerange=20250721-
```
### Data Provider
```bash
# Docker
cd data_provider && docker compose up -d
# Direct
cd data_provider && python main.py
# With custom config
CONFIG_PATH=./config.json python main.py
```
### Web UI
```bash
cd web && python app.py
# or via gunicorn:
gunicorn -w 4 -b 0.0.0.0:8123 app:app
# Deploy scripts:
cd web && ./deploy.sh # standard
cd web && ./deploy_venv.sh # Ubuntu 22.04+ (venv)
```
### Docker (Freqtrade)
```bash
sudo docker compose run --rm chanlun_btc backtesting -c ./user_data/Chan/config/<config>.json --strategy <StrategyName> --strategy-path ./user_data/Chan/strategies --timerange=20250721-
```
## Key Conventions
- All Chan theory classes are prefixed with `Chan` (e.g., `ChanBI`, `ChanZS`)
- Strategies import `ChanLun` and add `sys.path.append(os.path.dirname(os.path.dirname(os.path.abspath(__file__))))` to import from parent
- MACD params: `MACD(26, 52, 9)` by default (slow period 52 instead of standard 26)
- Enums in `ChanEnum.py` use `auto()` values
- `ChanKLC` is a linked-list style data structure with `.next`/`.pre` pointers
- The `TF_DF` class is the primary data container per timeframe
- K-line direction uses `Chan_KLINE_DIR` (UP/DOWN/COMBINE/INCLUDED)
- All text comments/commits are in Chinese

# Chan — 缠论分析引擎
把 OHLCV K 线拆成缠论结构(K 线单元 → 合并 K 线 → 分型 → 笔 → 线段 → 中枢 → 买卖点),
配一个 TradingView Charting Library 的 Web 界面,外加一套验证信号有效性的回测脚本。
标的不限:加密永续(ccxt)与 A 股(akshare)都走同一条分析链路。
```
chanlun/ 缠论引擎,纯 pandas/numpy,无外部指标库依赖
web/ Flask API + 图表界面
research/ 信号有效性验证脚本(step1 ~ step30
data/ 本地 K 线(freqtrade 的 feather 格式)
```
## 安装
需要 Python ≥ 3.11pandas 3.x / numpy 2.x 的要求,不是本项目代码的限制)。
```bash
python -m venv .venv
.venv/bin/pip install -r requirements.txt # 核心运行时,8 个包
.venv/bin/pip install -r requirements-dev.txt # 另加测试与 research/ 所需
```
## 跑 Web
```bash
cd web
../.venv/bin/python app.py # 默认 http://0.0.0.0:8128
```
从仓库根跑 `.venv/bin/python web/app.py` 也可以——Python 会把脚本所在目录放进 `sys.path`
但**不能用 `python -m web.app`**,也不能 `import web.app``web/` 内部是无前缀导入
`import config``from api.analyze import bp`),`-m` 方式下 `sys.path` 里是仓库根而不是
`web/`,会 `ModuleNotFoundError: No module named 'config'`
配置全部走环境变量,见 `web/config.py`
| 变量 | 默认值 | 用途 |
|------|--------|------|
| `FLASK_HOST` / `FLASK_PORT` | `0.0.0.0` / `8128` | 监听地址 |
| `DATA_SERVICE_URL` | `https://provider.jackyu66.com` | 行情 REST 源 |
| `DATA_SERVICE_WS_URL` | `wss://jackyu66.com/ws` | 行情 WebSocket 源 |
| `ASHARE_DP_URL` | `http://103.179.242.166:8000` | A 股数据源 |
| `CHAN_HTTP_PROXY` | 未设置则不走代理 | ccxt / HTTP 代理 |
| `MACD_FACTOR` / `MACD_SMOOTH` | `1` / `1` | MACD 周期倍数,默认 12/26/9 |
主要接口:`GET /api/analyze` 返回某标的某周期的完整缠论结构,`/api/klines/recent`
取最新 K 线,`/api/trend_filter``/api/trend_detail` 做多周期趋势筛选,
`/api/symbols``/api/search_stock``/api/sectors` 等负责标的检索。页面在 `/``/chan_tv`
## 作为库使用
```python
import pandas as pd
from chanlun import TF_DF
# 需要 date/open/high/low/close/volume 六列,date 为 datetime
df = pd.read_feather("data/binance/futures/BTC_USDT_USDT-1h-futures.feather")
tf = TF_DF(df, interval=1, timeframe="1h")
len(tf.klu_list) # K 线单元
len(tf.klc_list) # 合并 K 线(处理包含关系后)
len(tf.bi_list) # 笔
len(tf.seg_list) # 线段
len(tf.zs_list) # 中枢
tf.bi_list[-1].dir # Chan_BI_DIR.DOWN
tf.chanmacd # MACD 结构分析(背驰判定用)
```
**`interval` 的单位是分钟**,对传入的 df 做重采样;`interval=1` 是特例,表示原样使用、
不重采样。所以拿 1h 的 feather 要传 `interval=1`,拿 1m 数据想看 1h 才传 `interval=60`
```python
df1m = pd.read_feather("data/binance/futures/BTC_USDT_USDT-1m-futures.feather")
TF_DF(df1m, interval=5, timeframe="5m")
TF_DF(df1m, interval=60, timeframe="1h")
```
传错不会报错,只会静默给出错误周期的结构——1h 数据配 `interval=4` 相当于按 4 分钟
重采样,结果与 `interval=1` 完全相同。
## 分析流程
`TF_DF.init_TF_DF()` 按顺序做这几步,每步的实现在 `chanlun/pipeline/builders/` 下同名文件:
1. `resample_to_interval` — 重采样(`interval != 1` 时)
2. `add_indicators` — 追加 33 列指标(MACD / BBANDS / EMA / RSI / ATR 等)
3. `cal_kl_data``klu_list` — K 线单元
4. `get_klc_list``klc_list` — 按包含关系合并 K 线,并标记分型
5. `cal_bi_list``bi_list` — 笔
6. `cal_bi_zs_list_pure``bi_zs_list` — 笔中枢
7. `get_seg_list``seg_list` — 线段
8. `get_zs_list` / `get_big_zs_list` — 中枢与大级别中枢
9. `ChanMACD(klu_list)` — MACD 段 / 柱堆结构,供背驰判定
## 数据
`data/<交易所>/futures/<SYMBOL>-<周期>-futures.feather`,即 freqtrade 的下载格式,
`data/binance/futures/BTC_USDT_USDT-1h-futures.feather`
`research/lib/data.py` 负责定位:`BTC/USDT:USDT` + `1h` 会解析到上面这个路径,
找不到本地文件则回落到远端拉取。
## 测试
```bash
.venv/bin/python -m pytest chanlun/tests web/tests -q
```
`chanlun/tests/test_ta_compat.py` 有个**需要注意的陷阱**:它把 `chanlun/indicators/ta.py`
的输出逐 bar 钉在 TA-Lib 上,但 **TA-Lib 不存在时会静默跳过**。也就是说改了 `ta.py`
之后在没装 TA-Lib 的环境里跑,测试会显示通过,其实一项都没验证。改动那个文件时请先装:
```bash
sudo apt-get install -y libta-lib0 ta-lib-dev
.venv/bin/pip install TA-Lib technical
```
## 已知问题
- **`web/DEPLOY_GUIDE.md` 已失效**:它引用的 `deploy_venv.sh``stop_venv.sh`
`status_venv.sh` 等 6 个脚本都在 `7f393b9` 精简提交里删掉了,目前没有部署脚本。
两个 systemd unit 文件(`web/chanlun-web*.service`)仍可参考,但它们用 gunicorn
且写死端口 8123,与 `config.py` 默认的 8128 不一致,gunicorn 也不在依赖清单里。
- **`web/README.txt` 已过时**:它说的 `web/requirements.txt` 不存在,依赖清单在仓库根目录。
- **四个零引用的死文件**`chanlun/analysis/` 下的 `ChanPY.py``ChanLun_Classifier.py`
`Find_Trend.py``ChanHeng.py` 全项目无人引用。`ChanPY.py` 依赖未安装的外部 chan.py 库,
另外三个需要 matplotlib / mplfinance / xgboost / scikit-learn——这些都**不在**依赖清单里,
是有意为之。要用得自行安装。
