参数细节、返回值结构和已知陷阱。
---
## 1. 初始化与配置
### 配置来源(优先级从高到低)
1. **环境变量**
| 变量 | 默认 | 说明 |
|------|------|------|
| `BIGQMT_ACCOUNT_ID` | — | 资金账号 |
| `BIGQMT_REDIS_HOST` | `127.0.0.1` | Redis 地址 |
| `BIGQMT_REDIS_PORT` | `6379` | Redis 端口 |
| `BIGQMT_REDIS_DB` | `5` | Redis DB |
| `BIGQMT_REDIS_PASSWORD` | — | Redis 密码 |
| `BIGQMT_RPC_TRANSPORT` | `redis` | 传输方式 redis/zmq |
| `BIGQMT_RPC_TIMEOUT_SECONDS` | `6.0` | RPC 超时 |
2. **配置文件** `bigqmt_signal_trader_client_config.py`(在 PYTHONPATH 中,gitignored
3. **备选配置文件** `bigqmt_signal_trader_local_config.py`
### Python 初始化
```python
from bigqmt_signal_trader.xtquant_compat import StockAccount, configure, xt_trader, xtdata
configure() # 从配置/环境变量初始化
acc = StockAccount(xt_trader.client.account_id, "STOCK")
```
---
## 2. 行情数据 API
### 2.1 get_full_tick — 实时五档盘口
```python
xtdata.get_full_tick(code_list)
```
- **参数**: `code_list: list[str]`,如 `["000001.SZ", "600000.SH"]`;也支持整市场 `["SH"]`, `["SZ"]`
- **返回**: `dict[code -> dict]`,每只含 `lastPrice`/`open`/`high`/`low`/`lastClose`/`volume`/`amount`/
`bidPrice`(10档)/`askPrice`(10档)/`bidVol`/`askVol`/`time`/`stime`
- **CLI**: `python qmt.py tick 600000.SH 000001.SZ`
- **注意**: 整市场快照数据量大(5000+ 股),超时自动设 30 秒
### 2.2 get_market_data_ex — K线/历史行情
```python
xtdata.get_market_data_ex(
field_list=None, # ["close","open","high","low","volume","amount"] 或 None=全部
stock_list=None, # ["000001.SZ"]
period="1d", # "1d"/"1m"/"5m"/"15m"/"30m"/"60m"/"tick"
start_time="", # "YYYYMMDD" 或 "YYYYMMDDHHMMSS"
end_time="",
count=-1, # -1=不限
dividend_type="none", # "none"/"front"(前复权)/"back"(后复权)
fill_data=True, # 是否填充缺失
)
```
- **返回**: `dict[code -> pandas.DataFrame]`index 是时间戳字符串,列含 `time`(epoch ms)/`open`/`high`/`low`/`close`/`volume`/`amount`
- **CLI**: `python qmt.py kline 600000.SH --period 1d --count 60 --dividend front`
- **自愈**: 请求复权但服务端缺原始数据时(返回全 0),自动触发下载+重试
- **陷阱**: 前/后复权必须先在服务端下载原始数据,否则返回全 0(已自愈但仍可能首次慢)
### 2.3 get_instrument_detail — 合约详情
```python
xtdata.get_instrument_detail(stock_code) # 别名 get_instrumentdetail
```
- **返回**: `dict`,含名称/上市日/合约乘数/最小变动价位等约 30 字段
- **CLI**: `python qmt.py instrument 600000.SH`
### 2.4 get_stock_list_in_sector — 板块成分股
```python
xtdata.get_stock_list_in_sector(sector_name) # 如 "沪深A股", "科创板", "创业板"
```
- **返回**: `list[str]` 代码列表
- **CLI**: `python qmt.py sector "沪深A股"`
### 2.5 get_sector_list — 板块列表
```python
xtdata.get_sector_list()
```
- **返回**: `list[str]`
- **CLI**: `python qmt.py sector`
- **注意**: 大 QMT 环境 fallback 返回 13 个常用板块名(非完整列表)
### 2.6 get_trading_dates — 交易日历
```python
xtdata.get_trading_dates(market="SH", start_time="", end_time="", count=-1)
```
- **CLI**: `python qmt.py trading-dates --count 10`
### 2.7 get_north_finance_change — 北向资金
```python
xtdata.get_north_finance_change(period="1d")
```
- **CLI**: `python qmt.py north`
### 2.8 get_longhubang — 龙虎榜
```python
xtdata.get_longhubang(stock_list=["600000.SH"], start_time="", end_time="", count=5)
```
- **返回**: `pandas.DataFrame`
- **CLI**: `python qmt.py longhubang 600000.SH --count 5`
### 2.9 get_financial_data — 财务数据
```python
xtdata.get_financial_data(
stock_list=["000001.SZ"],
table_list=["Capital.CAPITAL"], # 表名
start_time="", end_time="",
)
```
- **CLI**: `python qmt.py financial 000001.SZ --tables Capital.CAPITAL`
### 2.10 download_history_data2 — 下载历史数据
```python

start_time="20240101", dividend_type="front",
)
```
- **返回**: `{"finished": N, "total": M}`
- **CLI**: `python qmt.py download 600654.SH --period 1d --start 20240101 --dividend front`
### 2.11 subscribe_whole_quote — 全推行情订阅
```python
sub_id = xtdata.subscribe_whole_quote(["SH","SZ"], callback=on_quote)
# ... 运行策略 ...
xtdata.unsubscribe_quote(sub_id)
```
- **机制**: 服务端真推送(非轮询),增量推送有变化的品种
- **CLI**: `python qmt.py quote-subscribe SH SZ --max 10 --timeout 30`
- **心跳**: 客户端 3 秒一次 keepalive,服务端重启后自动恢复
---
## 3. 账户/持仓/委托查询 API
### 3.1 query_stock_asset — 查询资产
```python
asset = xt_trader.query_stock_asset(acc)
```
- **返回属性**: `account_id` / `cash`(可用现金) / `frozen_cash` / `total_asset` / `market_value`
- **CLI**: `python qmt.py account`
- **容错**: RPC 失败时从 Redis 缓存 `bigqmt:positions:{account_id}` 读取
### 3.2 query_stock_positions — 查询全部持仓
```python
positions = xt_trader.query_stock_positions(acc)
```
- **返回属性**: `stock_code` / `stock_name` / `volume`(总持仓) / `can_use_volume`(可用) /
`avg_price`(成本) / `price`(最新价) / `market_value` / `frozen_volume` / `yesterday_volume`
- **CLI**: `python qmt.py positions [code]`
### 3.3 query_stock_position — 查询单只持仓
```python
pos = xt_trader.query_stock_position(acc, "600000.SH")
```
- **返回**: 单个对象或 `None`
### 3.4 query_stock_orders — 查询委托
```python
orders = xt_trader.query_stock_orders(acc, cancelable_only=False, strategy_name="")
```
- **返回属性**: `stock_code` / `order_type`(23=BUY,24=SELL) / `order_status` /
`order_volume` / `traded_volume` / `price` / `order_sysid` / `order_remark`
- **CLI**: `python qmt.py orders [--cancelable] [--strategy ""]`
- **⚠️ strategy_name 陷阱**: 下单时的 strategy_name 必须和查询时一致。服务端默认 `""` 返回全部;
客户端 `BigQmtXtTrader` 默认 `"bigqmt_signal_trader"`。用 `""` 查全部最安全。
### 3.5 query_stock_trades — 查询成交
```python
trades = xt_trader.query_stock_trades(acc, strategy_name="")
```
- **返回属性**: `stock_code` / `order_type` / `traded_volume` / `traded_price` /
`traded_at` / `order_sysid` / `trade_id`
- **CLI**: `python qmt.py trades`
### 3.6 委托状态码

## 4. 下单 API
### 4.1 order_stock — 同步下单
```python
from bigqmt_signal_trader.xtquant_compat import STOCK_BUY, STOCK_SELL, FIX_PRICE, LATEST_PRICE
order_id = xt_trader.order_stock(
acc, # StockAccount
stock_code, # "600000.SH"
order_type, # STOCK_BUY(23) / STOCK_SELL(24)
order_volume, # int,委托数量
price_type, # FIX_PRICE(11) / LATEST_PRICE(5)
price, # float,限价单价格(最新价时传 0)
strategy_name, # str
order_remark, # struser_order_id
)
```
- **返回**: `order_sys_id`(字符串) 或 `-1`(失败)
- **CLI**: `python qmt.py buy 600000.SH 100 --price 7.50 [--strategy s] [--remark r]`
- **CLI**: `python qmt.py sell 600000.SH 100 --price 7.50`
- **⚠️ 权限**: 服务端默认 `rpc_allow_order_methods=False`,必须显式开启才能下单
- **⚠️ 超时**: 超时后委托可能已提交,先查 `query_orders` 确认,避免重复下单
### 4.2 order_stock_async — 异步下单
```python
seq = xt_trader.order_stock_async(acc, code, order_type, vol, price_type, price, strategy, remark)
```
- **返回**: seq(结果通过 callback 回调)
### 4.3 order_stock_batch — 批量下单
```python
results = xt_trader.order_stock_batch(acc, orders, batch_id="")
# orders: list[dict],每项含 stock_code/action/volume/price/price_type/strategy_name
```
- **上限**: 500 条/批
### 4.4 信用交易委托类型
| 常量 | 值 | 用途 |
|------|-----|------|
| CREDIT_BUY | 23 | 担保品买入 |
| CREDIT_SELL | 24 | 担保品卖出 |
| CREDIT_FIN_BUY | 27 | 融资买入 |
| CREDIT_SLO_SELL | 28 | 融券卖出 |
| CREDIT_BUY_SECU_REPAY | 29 | 买券还券 |
| CREDIT_DIRECT_SECU_REPAY | 30 | 直接还券 |

---
## 5. 撤单 API
### 5.1 cancel_order_stock_sysid
```python
success = xt_trader.cancel_order_stock_sysid(acc, market, order_sysid)
# market: "SH" / "SZ" / ""
```
- **CLI**: `python qmt.py cancel <order_sysid> --market SH`
### 5.2 cancel_order_stock
```python
success = xt_trader.cancel_order_stock(acc, order_id)
# 等价于 cancel_order_stock_sysid(acc, "", order_id)
```
---
## 6. 回调系统
```python
from bigqmt_signal_trader.xtquant_compat import XtQuantTraderCallback
class MyCallback(XtQuantTraderCallback):
def on_stock_order(self, order): ... # 委托变更
def on_stock_trade(self, trade): ... # 成交推送
def on_order_error(self, error): ... # 委托错误
def on_cancel_error(self, error): ... # 撤单错误
def on_order_stock_async_response(self, resp): ...
def on_account_status(self, status): ...
xt_trader.register_callback(MyCallback())
xt_trader.start()
xt_trader.connect()
xt_trader.subscribe(acc)
```
事件推送通过 Redis pubsub 频道:
- `bigqmt:exec:order:{account_id}`
- `bigqmt:exec:trade:{account_id}`
- `bigqmt:exec:order_error:{account_id}`
- `bigqmt:exec:cancel_error:{account_id}`
---
## 7. 关键陷阱速查
### 7.1 strategy_name 不匹配
- 下单用 `strategy_name="rpc_test"` → 查询用 `strategy_name="bigqmt_signal_trader"` → 返回空
- **解决**: 查询时传 `strategy_name=""` 返回全部,或保持一致
### 7.2 下单静默失败
- `passorder` 调用成功但委托没进系统(QMT 风控拒绝但没报错)
- **解决**: 服务端下单后等 0.5 秒查 `query_orders` 确认;检查返回的 `server_error` 字段
### 7.3 复权 K 线返回全 0
- 服务端缺原始数据时,前/后复权返回的 close 全是 0.0
- **解决**: 先 `download_history_data2` 下载原始数据(客户端有自愈机制)
### 7.4 Transport 不匹配
- 客户端 redis / 服务端 zmq → ping 超时
- **解决**: 两端 `transport` 字段保持一致
### 7.5 QMT 必须运行在实盘模式
- 模拟模式下委托进 QMT 界面但不在真实委托队列,`query_orders` 查不到
- `order_stock` 返回 -1,触发 `on_order_error`
### 7.6 整市场快照数据量大
- `get_full_tick(["SH"])` 返回 5000+ 股完整盘口
- **解决**: 启用 `full_tick_cache` 或增大超时(已自动设 30 秒)
### 7.7 全推行情是增量的
- `subscribe_whole_quote` 的大 QMT 回调只推有变化的品种
- **解决**: 订阅成功后客户端自动调一次 `get_full_tick` 打底
### 7.8 下单超时与重复下单
- `order_stock` 超时 → 委托可能已提交但没收到响应
- **解决**: 超时后先查 `query_orders`/`query_trades` 确认状态,再决定是否重试

## 8. 常量速查
### 交易常量
| 常量 | 值 | 用途 |
|------|-----|------|
| STOCK_BUY | 23 | 股票买入 |
| STOCK_SELL | 24 | 股票卖出 |
| FIX_PRICE | 11 | 限价/指定价 |
| LATEST_PRICE | 5 | 最新价 |
| MARKET_PEER_PRICE_FIRST | 44 | 对手方最优价 |
### 账号类型
| 常量 | 值 |
|------|-----|
| FUTURE_ACCOUNT | 1 |
| SECURITY_ACCOUNT | 2 |
| CREDIT_ACCOUNT | 3 |
| FUTURE_OPTION_ACCOUNT | 5 |
| STOCK_OPTION_ACCOUNT | 6 |
### 期货委托类型(部分)
| 常量 | 值 | 用途 |
|------|-----|------|
| FUTURE_OPEN_LONG | 0 | 开多 |
| FUTURE_CLOSE_LONG_TODAY | 2 | 平今多 |
| FUTURE_OPEN_SHORT | 3 | 开空 |
| FUTURE_CLOSE_SHORT_TODAY | 4 | 平今空 |
| FUTURE_CLOSE_LONG_HISTORY | 6 | 平昨多 |
| FUTURE_CLOSE_SHORT_HISTORY | 7 | 平昨空 |
---
## 9. 直接 RPC 调用(绕过兼容层)
当兼容层方法不够用时,可直接调 RPC:
```python
from bigqmt_signal_trader.redis_rpc import call_redis_rpc
import redis
r = redis.Redis(host="...", port=6379, db=5, password="...")
resp = call_redis_rpc(r, "ACCOUNT_ID", "get_full_tick", {"codes": ["000001.SZ"]})
print(resp["data"]["000001.SZ"]["lastPrice"])
```
- **万能入口**: `xtdata.call_method("get_float_caps", stockcode="000001.SZ")`
- **方法别名映射**:
- `get_full_tick``get_ticks`
- `get_instrument_detail``get_instrument`
- `query_stock_asset``get_asset`
- `query_stock_positions``get_positions`
- `query_stock_orders``query_orders`
- `query_stock_trades``query_trades`
- `order_stock``submit_order`
- `cancel_order_stock``cancel_order`
### RPC 响应结构
```json
{
"ok": true,
"data": {...},
"error": "",
"server_error": "",
"handled_at": "2024-07-01 15:00:00"
}
```
- `ok=true`: `data` 为方法返回值(DataFrame 已序列化,客户端自动还原 pandas 对象)
- `ok=false`: `error` 为错误信息
- `server_error`: 额外诊断(如 passorder 提交但委托未进系统)
