通过以下两个函数获取某支股票的详情:

# 获取某支股票的单周期详情
def get_stock_data(stock, count, end_date, unit):
    return jq.get_bars(security=stock, fields=['date','open','high','low','close'], count=count, unit=unit, include_now=False, end_dt=end_date, fq_ref_date=None)

# 获取某支股票的多周期详情,可用于计算共振
def get_stock_data_multicycle(stock, count, end_date, units):
    map_unit = {}
    for u in units:
        data = jq.get_bars(security=stock, fields=['date','open','high','low','close'], count=count, unit=u, include_now=False, end_dt=end_date, fq_ref_date=None)
        map_unit[u] = data
    return map_unit

主函数代码示例

map_stock_data = get_stock_data_multicycle('000300.XSHG', 200, datetime.datetime.now(), ['5m', '15m', '30m'])
    for unit, stock_data in map_stock_data.items():
        macd = MACD(stock_data, 12, 26, 9)
        macd.show_macd()
