指标计算入口
QUANTAXIS的核心数据结构有一个方法叫add_func(func,args,*kwargs),作为一个指标入口,会返回一个和DataStruct中股票数量一致长度的Dataframe
QUANTAXIS有两种类型的指标:
基础指标(输入为Series的指标)
应用级指标(可应用于DataStruct的指标)
其中,基础指标是为了应用级指标做准备的,及对应于Series的分析和dataframe的分析的关系
基础类指标 [基本和同花顺/通达信一致]

自己写一个指标:
比如 绝路航标
import QUANTAXIS as QA
def JLHB(data, m=7, n=5):
    """
    通达信定义
    VAR1:=(CLOSE-LLV(LOW,60))/(HHV(HIGH,60)-LLV(LOW,60))*80; 
    B:SMA(VAR1,N,1); 
    VAR2:SMA(B,M,1); 
    绝路航标:IF(CROSS(B,VAR2) AND B<40,50,0);
    """
    var1 = (data['close'] - QA.LLV(data['low'], 60)) / \
        (QA.HHV(data['high'], 60) - QA.LLV(data['low'], 60)) * 80
    B = QA.SMA(var1, m)
    var2 = QA.SMA(B, n)
    return pd.DataFrame({'JLHB':QA.CROSS(B,var2)*(B<40)})
金叉死叉
def MACD_JCSC(dataframe, SHORT=12, LONG=26, M=9):
    """
    1.DIF向上突破DEA，买入信号参考。
    2.DIF向下跌破DEA，卖出信号参考。
    """
    CLOSE = dataframe.close
    DIFF = QA.EMA(CLOSE, SHORT) - QA.EMA(CLOSE, LONG)
    DEA = QA.EMA(DIFF, M)
    MACD = 2*(DIFF-DEA)
​
    CROSS_JC = QA.CROSS(DIFF, DEA)
    CROSS_SC = QA.CROSS(DEA, DIFF)
    ZERO = 0
    return pd.DataFrame({'DIFF': DIFF, 'DEA': DEA, 'MACD': MACD, 'CROSS_JC': CROSS_JC, 'CROSS_SC': CROSS_SC, 'ZERO': ZERO})
得到指标
QA.QA_fetch_stock_day_adv('000001','2017-01-01','2017-05-31').to_qfq().add_func(JLHB)
QUANTAXIS的指标类 QA_DataStruct_Indicators()
(新增于1.0.42)
指标类可以直接加载计算出来的指标
