【共享函数】绘制回测或模拟交易的买卖点

我们棒棒哒发表于：9 月 18 日 21：36回复(1)

注意: pyecharts本身存在bug , 如果绘图出现空白 , ctrl shift p 搜索 "信任notebook" ,点击信任 , 如果网页一直处于加载状态可以多刷新几次页面试试
还有问题的话可以重新建立一个notebook执行上述步骤

效果图:

用于在研究中获取回测信息,并将买卖点绘制在K线图中, 使用了pyecharts库 , 动手能力强的小伙伴们可以自己使用返回的overlip添加技术指标等显示在图上

(1) 初始化, 获取回测信息

回测ID（backtestId）:每个回测的唯一标识

TRADE_PLOT(ID = "回测ID")

初始化后将获得 trade_data 属性 , 是回测的所有交易记录详情

(2) 设置需要查看的标的(标的必须存在于交易列表中)

set_security('601866.XSHG' ,fq_date="last_day" ,forward_day=20  )

(3) 绘图

overlap = trade_plot.plot_base_bar()  #绘制K线图 
overlap

后续您也也可以自己添加副图或者主图指标到K线图中去 , 同时上传了py文件 plot_k.py , 可以直接上传到研究中 ,使用时 from plot_k import * 就可以直接调用了

注意: 如果绘图出现空白 , ctrl+shift+p 搜索 "信任notebook" ,点击信任 , 多刷新几次页面¶

示例 : K线添加MA线¶

trade_plot.plot_base_bar() 返回一个pyecharts 的 overlap , 大家也可以按照需求增加各种指标或副图上去 ,下边以最简单的ma为例

需要注意 xaxis_index 需要和K线使用的索引数据类型(datetime.date)保持一致,否则无法显示

def plot_ma(data,short,long):
    ma_short= price_data.close.rolling(window=short).mean().round(2)
    ma_long =price_data.close.rolling(window=long).mean().round(2)
    line = Line()
    line.add("ma{}".format(short),ma_short.index, ma_short.values)
    line.add("ma{}".format(long),ma_long.index, ma_long.values)
    return line

trade_plot.set_security('002385.XSHE',forward_day  = 30,fq_date=None)   #变更标的,检查 fq_date 参数及除权标记是否生效
overlap2 = trade_plot.plot_base_bar() 
price_data = trade_plot.price_data
overlap2.add(plot_ma(price_data,5,10))   # 添加MA图
