4.5 CCI • CCI 顺势指标探索
一、CCI指标简介与构造
顺势指标CCI由唐纳德拉姆伯特所创，是通过测量股价的波动是否已超出其正常范围，来预测股价变化趋势的技术分析指标。计算方法参考《技术指标系列（五）——CCI的顺势而为 》。
下面描绘出CCI与股价时序图走势
def cci(stock,start_date,end_date,windows): #设置股票，起始时间，以及CCI指标多少日
import pandas as pd
import numpy as np
from CAL.PyCAL import *
Alpha = 0.015
eq_TP = {}
eq_MATP = {}
eq_meanDev = {}
eq_CCI = {}
cal = Calendar('China.SSE')
windows = '-'+str(windows)+'B'
start_date = Date.strptime(start_date,"%Y%m%d")
end_date = Date.strptime(end_date,"%Y%m%d")
timeLength = cal.bizDatesList(start_date, end_date)
for i in xrange(len(timeLength)):
begin_date = cal.advanceDate(timeLength[i],windows,BizDayConvention.Unadjusted)
begin_date =begin_date.strftime("%Y%m%d")
timeLength[i] = timeLength[i].strftime("%Y%m%d")
eq_static = DataAPI.MktEqudAdjGet(secID=stock,beginDate=begin_date,endDate=timeLength[i],field=['secID','highestPrice','lowestPrice','closePrice'],pandas="1")
for stk in stock:
try:
eq_TP[stk] = np.array(eq_static[eq_static['secID'] == stk].mean(axis=1))
eq_MATP[stk] = sum(eq_TP[stk])/len(eq_TP[stk])
eq_meanDev[stk] = sum(abs(eq_TP[stk] - eq_MATP[stk]))/len(eq_TP[stk])
eq_CCI[stk].append((eq_TP[stk][-1] - eq_MATP[stk])/(Alpha * eq_meanDev[stk]))
except:
eq_CCI[stk] = []

eq_CCI = pd.DataFrame(eq_CCI)
cciSeries = pd.concat([Date,eq_CCI],axis =1)

return cciSeries
def cci_price_Plot(stock,start_date,end_date,windows):
cciSeries = cci(stock,start_date,end_date,windows)

table = pd.merge(cciSeries,closePrice, left_index=True, right_index=True, how = 'inner')

tableDate = table.set_index('Date')
tableDate.plot(figsize=(20,8),subplots = 1)
array([<matplotlib.axes.AxesSubplot object at 0x60037d0>,
<matplotlib.axes.AxesSubplot object at 0x602fa90>], dtype=object)
二、CCI指标简单应用
选取CCI处于100和150之间，开始处于上涨趋势的股票。关于windows，我们用quick_backtest做一个简单的优化
def cci(account,N=20):
Alpha = 0.015
eq_TP = {}
eq_MATP = {}
eq_meanDev = {}
eq_CCI = {}
eq_highPrice = account.get_attribute_history('highPrice',N)
eq_closePrice = account.get_attribute_history('closePrice',N)
eq_lowPrice = account.get_attribute_history('lowPrice',N)
for stk in account.universe:
eq_TP[stk] = (eq_highPrice[stk] + eq_closePrice[stk] + eq_lowPrice[stk])/3
eq_MATP[stk] = sum(eq_TP[stk])/len(eq_TP[stk])
eq_meanDev[stk] = sum(abs(eq_TP[stk] - eq_MATP[stk]))/len(eq_TP[stk])
eq_CCI[stk] = (eq_TP[stk][-1] - eq_MATP[stk])/(Alpha * eq_meanDev[stk])
