DuckDB 连接器文档

DataBase 类

类说明

用于连接和管理DuckDB数据库,处理币安交易数据的存储、因子计算和查询操作


初始化方法

def __init__(
    self,
    cache_path: str | None = None,
    db_path: str | None = None,
    read_only: bool = True
)

参数说明:

  • cache_path: 本地缓存路径(可选)
  • db_path: DuckDB数据库文件路径(可选,内存数据库如果未指定)
  • read_only: 是否以只读模式打开数据库(默认True)

主要公有方法

更新K线数据

def update_klines(self)

功能:

  • 遍历所有资产类别和时间频率,创建/更新K线数据表
  • 自动处理不同时间粒度的数据聚合
  • 进度条显示处理进度

更新因子数据

def update_factors(self)

功能:

  • 计算动量(momentum)、波动率(volatility)、贝塔(beta)等因子
  • 使用滑动窗口计算(窗口大小自动适配不同时间频率)
  • 进度条显示处理进度

获取因子数据

def df_factors(
    self,
    symbols: list[str] | None = None,
    freq: Literal["1m", "3m", "15m", "30m", "1h", "4h", "12h", "1d"] = "1m",
    asset_class: Literal["spot", "um"] = "um",
    start_date: str | None = None,
    end_date: str | None = None,
    order_by_timestamp: bool = False,
) -> pd.DataFrame

参数说明:

  • symbols: 交易对列表(可选,默认全部)
  • freq: 时间频率(默认1分钟)
  • asset_class: 资产类别(默认永续合约)
  • start_date/end_date: 时间范围(ISO格式字符串)
  • order_by_timestamp: 是否按时间排序

返回:

  • 包含以下字段的DataFrame: timestamp, symbol, close, return, momentum, volatility, beta

获取原始K线数据

def df_klines(
    self,
    symbols: list[str] | None = None,
    freq: Literal["1m", "3m", "15m", "30m", "1h", "4h", "12h", "1d"] = "1m",
    asset_class: Literal["spot", "um"] = "um",
    start_date: str | None = None,
    end_date: str | None = None,
    order_by_timestamp: bool = False,
) -> pd.DataFrame

参数同df_factors

返回:

  • 包含以下字段的DataFrame: symbol, timestamp, open, high, low, close, volume, quote_volume, taker_buy_volume, taker_buy_quote_volume

获取因子矩阵

def factors_matrix(
    self,
    symbols: list[str] | None = None,
    factor: Literal["return", "momentum", "volatility", "beta"] = "return",
    freq: Literal["1m", "3m", "15m", "30m", "1h", "4h", "12h", "1d"] = "1m",
    asset_class: Literal["spot", "um"] = "um",
    start_date: str | None = None,
    end_date: str | None = None,
) -> pd.DataFrame

特殊说明:

  • 返回以时间为索引、交易对为列名的二维矩阵
  • 使用PIVOT操作将纵向数据转换为横向矩阵
  • 适合量化分析中的因子研究

获取所有交易对

def list_all_symbols(self, asset_class: Literal["spot", "um"] = "um", data_type: Literal["klines", "metrics"] = "klines") -> list[str]:

参数说明:

  • asset_class: 资产类别(默认永续合约)
  • data_type: 数据类型(默认K线数据)

返回:

  • 包含所有交易对的列表

异常类型

  • DBReadOnlyError: 尝试在只读模式下执行写操作时抛出
  • DBError: 参数错误或无效操作时抛出

使用示例

# 初始化数据库连接
db = DataBase(db_path="binance.db", read_only=False)

# 更新数据
db.update_klines()
db.update_factors()

# 查询数据
df = db.df_factors(
    symbols=["BTCUSDT", "ETHUSDT"],
    freq="1h",
    start_date="2023-01-01",
    end_date="2023-01-31"
)

# 获取因子矩阵
matrix = db.factors_matrix(
    factor="momentum",
    freq="4h",
    asset_class="um"
)
