13.1 易经、传统文化 · 老黄历诊股
A：听说你今天满仓了？
B：是啊，听老专家说炒股要看黄历，我早上查了，今天宜开市。你呢，仓位如何？
A：策略有卖出信号，我昨天就空仓了。
S：怪不得今天跌停，原来是空头行动了。
最近小散发现了一个管用的择时方法:“看黄历”。4号忌交易，熔断；6号宜开市，红盘。7号宜开市，满仓杀入。然后就有了上面的对话。
等等，好像哪里不对。
为了让大家科学的赚钱，小散决定验证一下这个策略。
第一步：读入老黄历data
import pandas as pd
data = pd.read_csv('老黄历诊股.csv',encoding='GB18030')
data = data[['calendarDate','isOpen']]
buydata = data[data['isOpen'] == 1]
selldata = data[data['isOpen'] == -1]
print buydata.head(5)
print selldata.head(5)
calendarDate isOpen
3 2015-01-08 1
7 2015-01-14 1
8 2015-01-15 1
11 2015-01-20 1
27 2015-02-11 1
calendarDate isOpen
1 2015-01-06 -1
10 2015-01-19 -1
13 2015-01-22 -1
15 2015-01-26 -1
18 2015-01-29 -1
第二步A，买卖HS300ETF。根据老黄历信号，宜开市开仓，否则平仓。
buy_date = map(lambda x: x[0:4]+x[5:7]+x[8:10], buydata['calendarDate'].values.tolist())
sell_date = map(lambda x: x[0:4]+x[5:7]+x[8:10], selldata['calendarDate'].values.tolist())
start = '2015-01-01' # 回测起始时间
end = '2015-12-31' # 回测结束时间
benchmark = 'HS300' # 策略参考标准
universe = ['510310.XSHG'] # 股票池 # 策略参考标准
refresh_rate = 1 # 调仓频率，即每 refresh_rate 个交易日执行一次 handle_data() 函数
def initialize(account): # 初始化虚拟账户状态
pass
def handle_data(account): # 每个交易日的买入卖出指令
today=account.current_date.strftime('%Y%m%d')
for stk in account.universe:
if today in buy_date:
order_pct_to(stk, 1)
else:
if stk in account.avail_secpos:
order_to(stk, 0)
第二步B，买卖HS300ETF。根据老黄历信号，忌开市开仓，否则平仓。
start = '2015-01-01' # 回测起始时间
end = '2015-12-31' # 回测结束时间
benchmark = 'HS300' # 策略参考标准
universe = ['510310.XSHG'] # 股票池 # 策略参考标准
refresh_rate = 1 # 调仓频率，即每 refresh_rate 个交易日执行一次 handle_data() 函数
def initialize(account): # 初始化虚拟账户状态
pass
def handle_data(account): # 每个交易日的买入卖出指令
today=account.current_date.strftime('%Y%m%d')
for stk in account.universe:
if today in sell_date:
order_pct_to(stk, 1)
else:
if stk in account.avail_secpos:
order_to(stk, 0)
观察策略结果，虽然A，B都显著跑输大盘，但是A相对B仍然有5%的超额收益。真是应了那句老话：
本策略告诉小散：炒股有风险，新手慎入。
老黄历诊股.csv 数据来源：
1、DataAPI.TradeCalGet 得到交易日历，下载到本地。
2、根据汉典老黄历开市日历为isOpen字段赋值，宜开市为1，忌开市为-1，无提示为0。
3、上传到Data使用。
