1、TaLib與技術(shù)分析技術(shù)分析是股票分析十分有效直接的手段，在實際投資中我們常常需要計算各種簡單或復雜的技術(shù)指標來分析參考

對于技術(shù)指標的定義基本都大同小異，很多都是通用的且模塊化的東西

對于不會寫代碼或者不想自己寫函數(shù)計算這些技術(shù)指標的人而言，強大的Talib給我們帶來了福音

只需要調(diào)用Talib的函數(shù)，輸入簡單的參數(shù)就可以得到自己想要的結(jié)果

上面只是列舉了一部分，更多函數(shù)可以參見官網(wǎng)，點擊鏈接

3、如何應(yīng)用：MA實例從上面可以看到，MA這個函數(shù)的參數(shù)為：real = MA(close, timeperiod=30, matype=0)

close表示收盤價序列，timeperiod指定義好均線的計算長度即幾日均線，不輸入的話，默認為30日，matype可以默認不用輸入，然后就可以得到均線的值

所以簡單來講，只取獲取收盤價序列，就可以輕松計算MA值

下面以萬科A為例進行說明

data=DataAPI.MktEqudGet(ticker=u"000002",beginDate=u"20160601",endDate=u"20160804",field=u"secShortName,tradeDate,closePrice",pandas="1") #取數(shù)據(jù)

data['MA5'] = talib.MA(data['closePrice'].values, timeperiod=5) #調(diào)用talib計算5日均線的值

data.tail(10) #后十行結(jié)果

就這樣，我們便捷地計算出了均線，下面計算更復雜的EMA，MACD

有關(guān)EMA,MACD的基礎(chǔ)知識，可以參考社區(qū)帖子『研究｜技術(shù)指標｜第一彈』MACD

關(guān)于EMA,MACD計算的函數(shù)的描述是：

real = EMA(close, timeperiod=30)

macd, macdsignal, macdhist = MACD(close, fastperiod=12, slowperiod=26, signalperiod=9)

輸入?yún)?shù)：close是收盤價，timeperiod指的是指數(shù)移動平均線EMA的長度，fastperiod指更短時段的EMA的長度，slowperiod指更長時段的EMA的長度，signalperiod指DEA長度返回值：注意有些地方的macdhist = 2(dif-dea)，但是talib中MACD的計算是macdhist = dif-dea

data['EMA12'] = talib.EMA(data['closePrice'].values, timeperiod=12) #調(diào)用talib 計算12日移動移動平均線的值

data['EMA26'] = talib.EMA(data['closePrice'].values, timeperiod=26)

data['MACD'],data['MACDsignal'],data['MACDhist'] = talib.MACD(data['closePrice'].values)在構(gòu)建策略時也會更加方便。

4、策略實戰(zhàn)：雙均線策略當5日均線上穿60日均線，買入

當5日均線下穿60日均線，賣出

我們不再需要自己寫函數(shù)計算均線，只需要調(diào)用函數(shù)就可以方便的解決問題(對于更復雜的指標，talib的便捷就更加明顯)

import pandas as pd

import numpy as np

import talib

start = '2013-01-01' # 回測起始時間

end = '2016-07-01' # 回測結(jié)束時間

benchmark = 'HS300' # 策略參考標準

universe = set_universe('HS300')

capital_base = 1000000 # 起始資金

freq = 'd' # 策略類型，'d'表示日間策略使用日線回測，'m'表示日內(nèi)策略使用分鐘線回測

refresh_rate = 5 # 調(diào)倉頻率，表示執(zhí)行handle_data的時間間隔，若freq = 'd'時間間隔的單位為交易日，若freq = 'm'時間間隔為分鐘

def initialize(account): # 初始化虛擬賬戶狀態(tài)

pass

def handle_data(account): # 每個交易日的買入賣出指令

period1 = 5 #取5日數(shù)據(jù)

period2 = 60 #取60日數(shù)據(jù)

all_close_prices = account.get_attribute_history('closePrice', period2) # 獲取歷史closePrice數(shù)據(jù)

buy_list = [] # 備選買入清單

sell_list = [] # 賣出清單

for stk in account.universe:

prices = all_close_prices[stk]

if prices is None:

continue

try:

MA5 = talib.MA(prices, timeperiod=period1) # 計算5日均線

MA60 = talib.MA(prices, timeperiod=period2) #計算60日均線

except:

continue

# 買入賣出判斷

if MA5[-1]-MA60[-1] > 0: #talib計算返回的MA5是一個數(shù)組，對應(yīng)于日期，最后一個元素就是當前交易日前一天的5日均線值

buy_list.append(stk)

elif MA5[-1]-MA60[-1] < 0: #當5日均線下穿60日均線，賣出

sell_list.append(stk)

hold = []

buy = [] # 最終買入清單

# 買入賣出

for stk in account.valid_secpos:

# sell_list賣出

if stk in sell_list:

order_to(stk, 0)

# 其余繼續(xù)持股

else:

hold.append(stk)

buy = hold

for stk in buy_list:

# 若buy_list中股票有未買入的，加入

if stk not in hold:

buy.append(stk)

if len(buy) > 0:

# 等倉位買入

amout = account.referencePortfolioValue/len(buy) # 每只股票買入數(shù)量

for stk in buy:

num = int(amout/account.referencePrice[stk] / 100.0) * 100

order_to(stk, num)
