# A 股 ETF 自适应网格策略
策略目录为 `py-client/strategy/etf`,入口名称 `etf`,独立配置为
`py-client/etc/etf.yaml`。每只 ETF 总持仓上限 10 手1000 份),默认每次买入 1 手。
这是常见均值回归与波动率网格方法的工程组合,尚未完成历史收益回测。
## 方法分析
| 方法 | 优点 | 局限 | 本策略选择 |
| --- | --- | --- | --- |
| 固定价差网格 | 简单直观 | 不适应不同价格与波动率 | ATR 动态格距,设置百分比下限 |
| 均线回归 | 提供相对高低位置 | 单边下跌中均线会滞后 | MA60 作中轴,设置仓位上限 |
| BOLL 低吸 | 用价格分布寻找相对低位 | 触及下轨不代表跌势结束 | 下轨仅启动观察,反弹后再买 |
| 回撤止盈 | 上涨时跟随峰值 | 不能保证最高价退出 | 复用现有 GridTrailingTracker |
ATR 反映波动幅度不判断方向BOLL 为均线加减标准差倍数。定义参考
[Fidelity ATR](https://www.fidelity.com/learning-center/trading-investing/technical-analysis/technical-indicator-guide/atr)
及 [Fidelity BOLL](https://www.fidelity.com/learning-center/trading-investing/technical-analysis/technical-indicator-guide/bollinger-bands)。
默认参数是可调整的起点,不代表已经优化或保证收益。
## 指标与网格
历史日线直接读取 `http://go.apinb.com/a/get_daily?code=<证券代码>`,使用响应
`details` 中的 `ts_code / trade_date / open / high / low / close`。校验 `code=0`
证券归属、日期和 OHLC 后,按日期排序,排除当天及未来数据,再取最近 120 根。
每个标的每天计算一次并缓存,至少需要 60 根ATR 周期为 60 时至少需要 61 根。
接口样本未声明复权口径,策略使用接口原始价格,不自行假定或执行前复权。
- `M = 最近60根收盘价平均值`,固定 MA60。
- `TR = max(最高-最低, abs(最高-前收盘), abs(最低-前收盘))`
- ATR 默认 14 日:前 14 个 TR 平均作初值,后续按
`ATR = (前ATR × 13 + 当日TR) / 14` 进行 Wilder 平滑。
- BOLL 默认 20 日、2 倍总体标准差:`中轨=MA20``上下轨=MA20 ± 2σ`
- 格距 `G = max(ATR × atr_multiplier, M × min_grid_pct / 100, 0.001)`
向上取整至 0.001 元。均线作中轴ATR 决定每格宽度。
重复日期、非正数或非有限价格、价格关系异常、日线不足均不交易。
最后日线超过 15 个自然日也不交易;该检查只排除明显过期,不能替代交易所日历。
接口数据应更新至上一交易日。获取失败的标的每 5 分钟重试。
## 买入规则
1. 首仓在 `现价 <= min(BOLL下轨, M-G)` 时开始观察,不直接买入。
2. 复用 `DipWatch` 防接飞刀:下跌刷新低点,从低点反弹默认 0.61% 后触发;
观察默认 600 秒过期重置。反弹可站回下轨上方,但不能超过 MA60。
3. 加仓还须满足 `现价 <= 上次实际买入成交均价-G`,防止同价位连续补满。
初次接管已有仓位时,券商成本作为初始加仓基准。
4. 每次买入 `buy_hands × 100` 份;若买后超过 `max_hands × 100`,整笔跳过,
不临时缩量。配置强制 `1 <= buy_hands <= max_hands <= 10`
5. 买入预算为券商可用资金减账户现金安全线,再减所有本地待确认买单。
限价金额加预估佣金占用预算,多标的串行扣减。
示例MA60=4.00、G=0.05、下轨=3.90,价格进入 3.90 以下才观察;低点 3.88
反弹至 3.904 时超过 0.61%,可以提交固定手数。如果实际均价为 3.904
下一笔最高买价为 3.854,同时仍须满足低位触发和反弹确认。
## 止盈规则
1. `现价 >= max(BOLL上轨, M+G, 成本+G)`,且满足 `min_profit_pct`
预估价差收益大于买卖两侧佣金,才启动高位跟踪。
2. 启动时冻结格距。盈利格编号为 `floor((现价-成本)/冻结格距)`,复用
`GridTrailingTracker` 记录最高格;进入更高格更新峰值,跌回较低格时止盈。
这是跌破峰值格边界,不是从最高价回撤完整一个 ATR。
3. 启动后,即使回落到 BOLL 上轨或启动价以下,也继续判断回撤;卖出时仍须满足
最低利润和费用门槛。止盈启动后暂停补仓,不同时发买卖单。
4. **固定手数用于买入;止盈卖出当前全部可用整手份额**,数量为
`min(持仓, 券商可卖数量)` 向下取整到 100 份。零股暂不处理。
5. T+1 当天不可卖时继续记录峰值,翌日按券商 `can_use_volume` 判断。
清仓、实际成交改变仓位、外部数量或成本变化后重建基准;部分卖出后剩余仓位
重新等待高位启动,不把旧峰值带入新仓。
交易单位、0.001 元报价精度及股票 ETF 的 T+1 参考
[上交所 ETF 常见问题](https://www.sse.com.cn/assortment/fund/etf/question/)。
本策略没有自动止损单边下跌可能满仓后长期持有10 手上限只限制数量。
佣金参数按券商实际情况调整。费用门槛是估算,不逐笔归集历史买入最低佣金;
若券商持仓成本已含费用,该估算会偏保守。
## 委托、持仓与持久化
- 管理 `codes` 白名单内的已有持仓;`excluded_codes` 优先排除。配置外证券不买卖。
-`ETF-BUY-*` / `ETF-SELL-*` 为本地编号,标签 `etf`,当前价按 0.001 元
精度提交限价。复用 OrderBook只自动撤销超时 120 秒的 ETF 前缀委托。
- 同标的全账户买卖在途、未知委托状态或在途份额都会阻止新单。
行情缺少 `timetag`、不是当天或超过默认 90 秒,也不交易。
- 下单前原子保存意图HTTP 成功、超时或失败均不会自动解除锁。
必须收到终态53/54/56/57并且券商持仓与累计成交量相符才能继续。
部分成交按实际数量核对,买入必须取得实际成交均价才推进下一格。
- 状态位于 `{qmt_data_dir}/etf/{账户SHA256}/state.json`,保存实际买入基准、
止盈峰值、冻结格距和未确认委托;重启恢复,损坏不静默覆盖。
- 同一 ETF 不适合同时由人工或其他策略频繁交易。在途期间外部改变持仓,会暂停核对。
若跨日后柜台不再返回未确认订单,则持续暂停该标的,需要核对历史订单与持仓后
人工处理状态,不按超时自动重发。有未确认委托的标的不能直接从配置移除。
## 启用
1. 修改 `etc/etf.yaml` 的标的及参数。示例仅示范格式,请选择实际交易的 A 股股票 ETF
代码形态检查不验证基金投资范围。
2. 主机对应的账户 YAML 设置:
```yaml
strategy: etf
etf_config_path: etf.yaml
enable_auto_ipo: false
```
路径相对账户配置目录,也支持绝对路径;不填默认 `etc/etf.yaml`。
`account_id`、`min_cash_ratio` 继续生效。公共校验仍要求 `buy_value`、
`grid_step_pct` 为正,但 ETF 不用它们计算数量或格距。
关闭 IPO 是此处示例选择ETF 决策不依赖 IPO 或远端股票信号。
3. 无需修改 QMT 服务端或 `sdk/`。历史接口适配完全位于 `strategy/etf/data.py`
实时行情、持仓和交易继续使用已有 QMT SDK。
4. 确认外部接口提供配置 ETF 的足量、最新日线。HTTP 错误、业务失败、空列表、
证券代码不一致或数据异常都会跳过该标的,不改用其他证券数据。
2026-09-17 联通验证中,股票样本 `600584.SH` 成功返回 200 条,示例 ETF
`510300.SH` 返回 404需要数据服务覆盖实际配置的 ETF 后才能正常运行。
5. 按现有方式运行 `python main.py`。每 30 秒执行午休暂停15:00 退出。
本次新增不会自动切换已有实盘账户,也没有进行实盘委托。
## 离线验证
在 `py-client` 中运行:
```powershell
python -m unittest discover -s tests -p test_etf.py -v
python -m unittest discover -s tests -v
```
覆盖指标、未收盘日线排除、反弹确认、固定手数、限仓、资金共享、部分成交、拒单、
快照延迟、T+1、重启防重、峰值恢复、状态损坏、外部日线接口与异常响应。
离线行为验证不等同于历史收益回测或实盘联调。
