# 4.5 CCI • CCI 顺势指标探索
> 来源:https://uqer.io/community/share/55f28179f9f06c1ea681fa40
## 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 》](https://uqer.io/community/share/55f28179f9f06c1ea681fa40)。
下面描绘出CCI与股价时序图走势
```py
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] = []
Date = pd.DataFrame(timeLength)
eq_CCI = pd.DataFrame(eq_CCI)
cciSeries = pd.concat([Date,eq_CCI],axis =1)
cciSeries.columns = ['Date','CCI']
return cciSeries
def cci_price_Plot(stock,start_date,end_date,windows):
cciSeries = cci(stock,start_date,end_date,windows)
closePrice = DataAPI.MktEqudAdjGet(secID=stock,beginDate=start_date,endDate=end_date,field=['closePrice'],pandas="1")
table = pd.merge(cciSeries,closePrice, left_index=True, right_index=True, how = 'inner')
return table
```
```py
import pandas as pd
import numpy as np
from CAL.PyCAL import *
cal = Calendar('China.SSE')
table = cci_price_Plot(['600000.XSHG'],'20080531','20150901',30) #绘制浦发银行的CCI与股价对比图
tableDate = table.set_index('Date')
tableDate.plot(figsize=(20,8),subplots = 1)
array([,
], 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
```py
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])
return eq_CCI
```
```py
start = '2010-08-01' # 回测起始时间
end = '2014-08-01' # 回测结束时间

capital_base = 100000 # 起始资金

refresh_rate = 20 # 调仓频率,表示执行handle_data的时间间隔,若freq = 'd'时间间隔的单位为交易日,若freq = 'm'时间间隔为分钟
sim_params = quartz.sim_condition.env.SimulationParameters(start, end, benchmark, universe, capital_base)
idxmap_all, data_all = quartz.sim_condition.data_generator.get_daily_data(sim_params)
```
```py

print 'window annualized_return sharpe max_drawdown'
for window in range(10, 100, 5):
strategy = quartz.sim_condition.strategy.TradingStrategy(initialize, handle_data)
bt_test, acct = quartz.quick_backtest(sim_params, strategy, idxmap_all, data_all,refresh_rate = refresh_rate)
perf = quartz.perf_parse(bt_test, acct)
print ' {0:2d} {1:>7.4f} {2:>7.4f} {3:>7.4f}'.format(window, perf['annualized_return'], perf['sharpe'], perf['max_drawdown'])
