1. 现在是否有类似zipline的record函数，在before_trading,handle_bar中调用记录相关指标？

zipline.api.record

zipline.api.record(self, *args, **kwargs)
Track and record values each day.

Parameters:	
**kwargs

The names and values to record.

Notes

These values will appear in the performance packets and the performance dataframe passed to analyze and returned from run_algorithm().

2. logger.info好像有一些bug,在Spyder中回测时会重复打印.

代码000540.XSHE，时间2015-03-31~2015-04-01，价格变动一倍多。可能是除权等出现的问题。
该数据问题不是个例。

看到文档中说到可以用symbol来创建instrument, 不一定需要知道code.XSHE这类的id
实际操作中，instruments(['平安银行', '000024.XSHE'])会报错：ERROR: order_book_id 平安银行 not exists!

设置如下：
context.commission = 0.
context.slippage = 0.
init_cash = 10000000
落单如下：
在2014年1月1日全仓 买入000001 股票
测试结果如下：（20140101的交易情况）
[Trade({'order_book_id': '000001.XSHE', 'order_id': '50da6d406a614b049717effec75f7f77', 'tax': 0, 'commission': 5, 'amount': 1412400, 'price': 7.0800000000000001, 'date': Timestamp('2014-01-01 15:00:00', offset='D')})]
我的疑问：
commission 等于5 是怎么来的，price如何确定的，amount又是怎样？俩乘起来会不会超过初始资金10000000？？？？？？？？？？？？？

看到网站上可以实时模拟，看了一下开源的代码好像没发现实时模拟的功能。

用sector()时提示 'sector()' is not defined

看了源码貌似还不支持做空，请问RQ何时能加入做空机制呢？？？

像zipline一样ingest？

按照RQalpha的指导，测试了rsi策略。
背景：
本地的.rqalpha数据不是最新，但是有2014-1-1 到2016-1-1的数据
步骤：
运行以下命令，将开始回测
cd examples
rqalpha run -f multi_rsi.py -s 2014-01-01 -e 2016-01-01 -o result.pkl --plot
注 ： 策略完全就是RQalpha的例子，没有什么改动。
error提示:

[2016-08-31 23:54:59.421540] ERROR: user_log: order_shares 601988.XSHG amount is 0.
测试结果：
结果和RQalpha的例子的结果是一致的。
疑问：
为什么会有这样的日志？INFO和ERROR说的是个什么？这个ERROR会不会影响到测试的准确性？INFO和ERROR在RQalpha项目里那个py文件可以查到？谢谢

我通过最终的交易报告发现,每天交易使用的是当天的收盘价,这是否不够合理呢?
我想在每天的开盘时就进行所有的交易行为才更合理一些.
或者能否在代码中通过参数可以设置handle_bar的触发逻辑是使用当天开盘就进行交易,还是在当天收盘时才进行交易.

rqalpha examples -d ./ 或 rqalpha examples -d c:\
等在当前目录下或c:都没有创建出examples 目录，而且静默失败，没有任何提示。
不知道我哪里搞错了。

rqalpha 编译过程都ok，而且 rqalpha version 显示 （0,3,0）

运行
rqalpha run -f gold_cross.py -s 2014-01-01 -e 2016-01-01 -o result.csv

而且我第一次跑那个buy_and_hold例子的时候csv文件还是正常的，这是什么问题？

我用的是anaconda python3.5 64位，发现PyQt4没有3.5的版本。
请问怎么让解决呢？

数据查询相关函数

get_fundamentals - 查询财务数据

get_fundamentals(query, entry_date=None, interval=None, report_quarter=True)
获取历史财务数据表格。目前支持**市场超过400个指标，具体请参考财务数据文档。目前仅支持**市场。需要注意，一次查询过多股票的财务数据会导致系统运行缓慢。

我在ubuntu16.04上跑 rqalpha run -f multi_rsi.py -s 2014-01-01 -e 2016-01-01 -o result.pkl， 结果自己跑出个图出来。在os x上运行也有同样的问题。

注意到目前的data bundle更新时间好像不固定，能否于当日收盘后固定时间自动更新data bundle，谢谢！ @cedricporter @hzliu

在全英文系统中的中文显示问题，plot 结果显示中文乱码

1. rqalpha update_bundle 并未在~/.rqalpha 下发现对应目录，是不是应有个bundle目录出现
2. 如果执行 rqalpha update_bundle -d c:\ 该命令是否会删除C目录下文件？ 造成系统崩溃？ 请检查一下。

改了一些东西，发现不起作用，debug发现跑到lib里面了。应该是运行的时候跑了安装好的rqalpha。

试了试直接调用 main，发现报错。。

在'dividend.bcolz'文件中，猜测：

下载下来数据：

同花顺数据：

2015年公告数据：

数据源跟官方不一致很可能造成回测的失误呀。。
希望能确保数据源的准确性

该开源项目可以做空吗？？？

1、用examples/simple_macd.py 进行测试，
时间周期：2014-01-04\2015-01-04
资金默认：100000
回测周期：每日
从代码与复制到ricequant，出现现金为负情况：

看算多少股时，context.portfolio.cash/bar_dict[context.s1].close类似此，买多少股的时候没有把交易费用加进去？

运行：
rqalpha run -f C:\Users\91963_000\Desktop\rqalpha\examples\golden_cross.py -s 2013-01-01 -e 2015-01-01 --plot
就报这个错误。查了下网上说是编码问题，目前操作系统win8。
。。。。。想问下是不是我要去装个linux虚拟机来跑，还是说有其他简单的解决方法。

提前感谢

在init函数中使用：
context.commission = 0.02
最终的commission是2%，并不是0.02%。

commission.py文件中没有对设定的值再除100

请问如何使用自己的行情作为回测依据呢？比如我有外盘数据，也想用于回测，如何自定义产品？

我看了代码，好像只有这个方法能拿到所有的股票？既然代码已经实现了，为什么没公开出来呢。

1、请问如何下止损单和止盈单？
2、如果我设置最大持股天数，到达时间了，以开盘价或者收盘价卖出，是否可以实现？
谢谢解答！

之前有个问题的回答是data_accesser 但是能不能提供一个详细的自定义数据源的教程？

或者是否可以开放本地数据缓存结果，这样会有人做出本地数据导入导出工具的。

from PyQt4 import QtCore, QtGui

因为qt,pyqt,matplotlib,spyder这些都更新了，已经没有qt4，所以出现了问题
