# 快速开始指南
|
||
|
||
## 1. 安装依赖
|
||
|
||
```bash
|
||
pip install fastapi uvicorn uvloop pydantic requests
|
||
```
|
||
|
||
## 2. 启动服务
|
||
|
||
```bash
|
||
# 在workspace目录下运行
|
||
python trading_server.py
|
||
```
|
||
|
||
输出:
|
||
```
|
||
============================================================
|
||
启动行情分析交易服务
|
||
============================================================
|
||
[INFO] 服务将运行在 http://localhost:5858
|
||
[INFO] API文档: http://localhost:5858/docs
|
||
[INFO] 备用文档: http://localhost:5858/redoc
|
||
============================================================
|
||
```
|
||
|
||
## 3. 验证服务
|
||
|
||
### 方式 A: 运行自动化测试
|
||
```bash
|
||
python test_trading_service.py
|
||
```
|
||
|
||
### 方式 B: 手动测试 (curl)
|
||
```bash
|
||
# 健康检查
|
||
curl http://localhost:5858/health
|
||
|
||
# 查看服务状态
|
||
curl http://localhost:5858/status
|
||
```
|
||
|
||
### 方式 C: 访问API文档
|
||
打开浏览器访问: [http://localhost:5858/docs](http://localhost:5858/docs)
|
||
|
||
## 4. 使用交易工具
|
||
|
||
### 方式 A: 交互式命令行工具
|
||
```bash
|
||
python trade_client.py
|
||
```
|
||
|
||
菜单示例:
|
||
```
|
||
======================================================
|
||
交易指令发送工具
|
||
======================================================
|
||
✓ 服务已连接
|
||
|
||
请选择操作:
|
||
1. 发送买入订单
|
||
2. 发送卖出订单
|
||
3. 查看待执行指令
|
||
4. 查看统计数据
|
||
5. 清空指令
|
||
0. 退出
|
||
|
||
请输入选项 (0-5):
|
||
```
|
||
|
||
### 方式 B: 代码调用
|
||
```python
|
||
from trade_client import TradeInstructionClient
|
||
|
||
client = TradeInstructionClient()
|
||
|
||
# 发送买入订单
|
||
result = client.send_buy_order("gold", 0.01, 5000, 5100)
|
||
print(result)
|
||
|
||
# 发送卖出订单
|
||
result = client.send_sell_order("eurusd", 0.02, 1.0950, 1.0850)
|
||
|
||
# 查看待执行指令
|
||
trades = client.get_pending_trades()
|
||
|
||
# 查看统计数据
|
||
stats = client.get_statistics(count=5)
|
||
```
|
||
|
||
### 方式 C: HTTP请求
|
||
|
||
> **说明**: 对于 `POST /send_trade_instructions` 接口,若指令中未提供 `tp` 或 `tp<=0`,服务端会自动设置为 `0.005`;`sl`缺失则保留为`0.0`。
|
||
>
|
||
> **价格验证规则**:
|
||
> - 买入指令必须满足 `sl < price < tp`。
|
||
> - 卖出指令必须满足 `tp < price < sl`。
|
||
> 若同时指定了 sl 与 tp 但不满足条件,该条指令会被拒绝。
|
||
|
||
```bash
|
||
# 发送买入订单
|
||
curl -X POST "http://localhost:5858/send_trade_instructions" \
|
||
-H "Content-Type: application/json" \
|
||
-d '[
|
||
{
|
||
"symbol": "gold",
|
||
"action": "b",
|
||
"mount": 0.01,
|
||
"sl": 5000,
|
||
"tp": 5100
|
||
}
|
||
]'
|
||
|
||
# 查询待执行指令
|
||
curl "http://localhost:5858/query_pending_trades"
|
||
|
||
# 查询统计数据
|
||
curl "http://localhost:5858/query_statistics?count=5"
|
||
```
|
||
|
||
## 5. MT5 EA集成
|
||
|
||
MT5 EA已经配置好,只需确保:
|
||
|
||
1. **MT5已启用WebRequest**
|
||
- 在MT5中:工具 -> 选项 -> EA交易
|
||
- 勾选"WebRequest用于脚本...", 并添加 `localhost:5858` 到允许列表
|
||
|
||
2. **启动EA**
|
||
- 在黄金(GOLD)品种的图表上加载 `wangxxGold.mq5`
|
||
- 确保EA显示为 ✓ 启用
|
||
|
||
3. **工作流程**
|
||
```
|
||
交易员发送指令 → Python服务 → EA获取指令 → 执行交易
|
||
|
||
EA每分钟→ 统计数据 → Python服务 → 交易员查询统计
|
||
```
|
||
|
||
## 6. 常见操作
|
||
|
||
### 发送一个黄金买入单
|
||
|
||
**命令行**:
|
||
```bash
|
||
# 交互式
|
||
python trade_client.py
|
||
# 选择 1,然后输入参数
|
||
|
||
# 或直接 Python
|
||
python -c "
|
||
from trade_client import TradeInstructionClient
|
||
client = TradeInstructionClient()
|
||
result = client.send_buy_order('gold', 0.01, 5000, 5100)
|
||
print(result)
|
||
"
|
||
```
|
||
|
||
**HTTP**:
|
||
```bash
|
||
curl -X POST "http://localhost:5858/send_trade_instructions" \
|
||
-H "Content-Type: application/json" \
|
||
-d '[{"symbol":"gold","action":"b","mount":0.01,"sl":5000,"tp":5100}]'
|
||
```
|
||
|
||
### 查看待执行指令
|
||
|
||
```bash
|
||
python trade_client.py
|
||
# 选择 3
|
||
```
|
||
|
||
或:
|
||
```bash
|
||
curl "http://localhost:5858/query_pending_trades"
|
||
```
|
||
|
||
### 查看统计数据
|
||
|
||
```bash
|
||
python trade_client.py
|
||
# 选择 4
|
||
```
|
||
|
||
或:
|
||
```bash
|
||
curl "http://localhost:5858/query_statistics?count=10"
|
||
```
|
||
|
||
### 清空指令
|
||
|
||
```bash
|
||
# 清空所有
|
||
curl -X DELETE "http://localhost:5858/clear_trades"
|
||
|
||
# 只清空黄金指令
|
||
curl -X DELETE "http://localhost:5858/clear_trades?symbol=gold"
|
||
```
|
||
|
||
## 7. 实时监控
|
||
|
||
### 查看服务状态
|
||
```bash
|
||
watch -n 1 'curl -s http://localhost:5858/status | python -m json.tool'
|
||
```
|
||
|
||
输出示例:
|
||
```json
|
||
{
|
||
"status": "running",
|
||
"pending_trades": {
|
||
"GOLD": 2,
|
||
"EURUSD": 1
|
||
},
|
||
"total_pending": 3,
|
||
"statistics_records": 8,
|
||
"timestamp": "2026-03-04T14:35:22.123456"
|
||
}
|
||
```
|
||
|
||
## 8. 故障排查
|
||
|
||
### 问题 1: 连接被拒绝
|
||
**症状**: `Connection refused on localhost:5858`
|
||
|
||
**解决**:
|
||
```bash
|
||
# 检查服务是否运行
|
||
ps aux | grep trading_server.py
|
||
|
||
# 检查端口占用
|
||
lsof -i :5858
|
||
|
||
# 重启服务
|
||
pkill -f trading_server
|
||
python trading_server.py
|
||
```
|
||
|
||
### 问题 2: 指令没有执行
|
||
**检查步骤**:
|
||
1. 确认指令已发送: `curl http://localhost:5858/query_pending_trades`
|
||
2. 检查EA日志: MT5 → 日志标签
|
||
3. 确认EA已启用: 图表角上有绿色 ✓ 标记
|
||
4. 检查WebRequest权限已启用
|
||
|
||
### 问题 3: 统计数据为空
|
||
**原因**: EA还没有发送统计数据
|
||
|
||
**验证**:
|
||
1. 等待至少1分钟(EA每分钟发送一次)
|
||
2. 检查EA是否在运行
|
||
3. 查看EA的日志输出
|
||
|
||
## 9. 扩展集成
|
||
|
||
### 与外部系统集成
|
||
|
||
```python
|
||
# 与量化分析系统集成
|
||
from trade_client import TradeInstructionClient
|
||
|
||
def your_analysis_function():
|
||
# 您的分析逻辑
|
||
buy_signal_gold = True
|
||
|
||
if buy_signal_gold:
|
||
client = TradeInstructionClient()
|
||
client.send_buy_order("gold", 0.01, 5000, 5100)
|
||
```
|
||
|
||
### 定时任务
|
||
|
||
```python
|
||
import schedule
|
||
import time
|
||
from trade_client import TradeInstructionClient
|
||
|
||
client = TradeInstructionClient()
|
||
|
||
def check_and_trade():
|
||
# 定期检查并下单
|
||
stats = client.get_statistics(1)
|
||
# 您的逻辑...
|
||
|
||
schedule.every(5).minutes.do(check_and_trade)
|
||
|
||
while True:
|
||
schedule.run_pending()
|
||
time.sleep(1)
|
||
```
|
||
|
||
## 10. 下一步
|
||
|
||
- 详细API文档: [README.md](README.md)
|
||
- 自动化测试: `python test_trading_service.py`
|
||
- API交互式文档: http://localhost:5858/docs
|
||
- 性能监控: `curl http://localhost:5858/status`
|
||
|
||
## 11. 后续优化
|
||
|
||
虽然当前HTTP性能足够,但可考虑:
|
||
|
||
1. **增加日志持久化**
|
||
- 添加SQLite保存历史数据
|
||
- 支持离线分析
|
||
|
||
2. **添加WebSocket支持**
|
||
- 实时推送行情变化
|
||
- 实时订单状态更新
|
||
|
||
3. **前端管理界面**
|
||
- Web Dashboard
|
||
- 实时图表展示
|
||
- 一键下单功能
