克隆策略

方法一:通过print查询

In [9]:
def initialize(context):
    pass
def handle_data(context, data):
    stock_1 = '000002.SZA'
    stock_2 =  '600519.SHA'
    wanke_price = data.current(context.symbol(stock_1), 'price')
    gzmt_price = data.current(context.symbol(stock_2) , 'price')
    print('万科价格:', wanke_price)
    print('贵州茅台价格:', gzmt_price)
m6 = M.trade.v2(
    instruments=['000002.SZA', '600519.SHA'],
    start_date='2017-07-15',

    handle_data=handle_data,
    plot_charts=False,     
)

方法二:通过record函数记录下来,回测完成后在回测结果中查询

def initialize(context):
    pass
def handle_data(context, data):
    stock_1 = '000002.SZA'
    stock_2 =  '600519.SHA'
    # 通过record函数记录下来,以便回测结束以后可以查询
    record(wanke=data.current(context.symbol(stock_1), 'price'), gzmt=data.current(context.symbol(stock_2) , 'price'))

m6 = M.trade.v2(
    instruments=['000002.SZA', '600519.SHA'],
    start_date='2017-07-15',
    end_date='2017-08-01',
    initialize=initialize,
    handle_data=handle_data,
    plot_charts=False,     
) 
# 回测结果中进行查询
