交易日历

Project description

Trading Calendars(tcalendars)

交易日历,用于交易时间的判断。当前支持的市场有:

  • 中国股票市场(2005年1月1日起)

安装

pip install playwright
playwright install chromium

pip install tcalendars

缓存

  • StockNameCodeHelper.get_stock_code_by_english_name / StockNameCodeHelper.get_stock_info_by_english_name 会通过 Playwright 调用 Yahoo Finance 搜索接口
  • 所有数据缓存统一存放在 tcalendars/cache/ 目录下:
    • 数据库:tcalendars/cache/data.dat (SQLite 格式,包含交易日历、股票名称代码、基金名称代码等)
    • Yahoo Finance 查询:tcalendars/cache/.yfinance_cache(JSON 格式,启动时自动加载到内存缓存)
  • .yfinance_cache 超过 60 天的缓存不会加载到内存(删除该文件可重建缓存)

示例

代码示例

from tcalendars import TradingCalendars

calendar = TradingCalendars()
# 判断2023年1月1日是否为交易日
calendar.is_trading_day('2023-01-01')

# 输出:['2023-01-03', '2023-01-04', '2023-01-05']

# 获取2023年1月1日所在的交易日,如果1月1日不是交易日,则返回后一个交易日
calendar.get_trading_day('2023-01-01')
# 输出:'2023-01-03'

from tcalendars import StockNameCodeHelper

helper = StockNameCodeHelper()

# 根据股票代码获取股票名称
helper.get_stock_name('000001')
# 输出:'平安银行'

# 根据股票名称获取股票代码
helper.get_stock_code('平安银行')
# 输出:'000001'

# 根据基金名称获取基金代码
fund_helper.get_fund_code('华夏成长混合')

# 查询基金关联份额
fund_helper.query_shares('000001')

# 按关键词搜索基金名称
fund_helper.search_by_keyword('华夏')
