## 快速开始

### 安装

```bash
pip install emutrader
```

### 基础使用

```python
from emutrader import get_jq_account

# 获取JoinQuant兼容账户
account = get_jq_account(
    strategy_name="my_strategy",
    initial_cash=100000,
    account_type="STOCK"
)

# 标准JQ接口 - 零学习成本
print(f"总资产: {account.account_info.total_value}")
print(f"可用资金: {account.account_info.available_cash}")

# JQ标准下单
order_id = account.order_shares("000001.SZ", 1000)
print(f"订单ID: {order_id}")
```

### 高级使用

```python
from emutrader import AccountHandlerFactory, SQLiteStorage, CacheManager

# 使用工厂模式创建处理器
handler = AccountHandlerFactory.create_handler("STOCK", "strategy", 0)

# 配置持久化存储
storage = SQLiteStorage("accounts.db")
cache_manager = CacheManager(storage)

# 查看支持的账户类型
print("支持的账户类型:", AccountHandlerFactory.get_supported_types())
```

## 🎯 使用场景

### 1. JoinQuant策略迁移
```python
# 原JQ策略代码保持完全不变
def initialize(context):
    pass
    
def handle_data(context, data):
    # 使用标准JQ接口，零修改运行
    account_info = context.portfolio.account_info
    order_shares("000001.XSHE", 1000)
```

### 2. 多账户策略管理
```python
# 同时管理多个账户类型
accounts = {
    "股票": get_jq_account("stock_strategy", 100000, "STOCK"),
    "期货": get_jq_account("future_strategy", 200000, "FUTURE"),
    "信用": get_jq_account("credit_strategy", 150000, "CREDIT")
}

for name, account in accounts.items():
    print(f"{name}账户总资产: {account.account_info.total_value}")
```

### 3. 高性能量化系统
```python
# 配置高性能缓存和存储
from qsm_account import CacheManager, SQLiteStorage

storage = SQLiteStorage("prod_accounts.db")
cache_manager = CacheManager(
    storage, 
    max_size=5000,  # 大容量缓存
    ttl_seconds=60   # 1分钟TTL
)

# 性能监控
stats = cache_manager.get_cache_stats()
print(f"缓存命中率: {stats['hit_rate']:.2%}")
```
