原因查到了，都是889历史数据导致该问题出现，最好的办法就是不要下载889历史就行了
mongodb db_bar_data默认以UTC储存日期，格式如下2010/1/4 UTC 上午12:00:00
请教各位，要怎样把策略实例里面bar.datetime做成db_bar_data的datetime UTC格式，以便访问db_bar_data某一条指定日期的记录？
公众号获取到rsj_tool.py 和rsj_dmi_strategy.py两个文件，放入C:\Users\ccc\strategies里，打开CTA回测触发如下异常，请问该如何让rsj_dmi_strategy正常运行？
现在的版本是
11:48:19 初始化CTA回测引擎
11:48:19 策略文件strategies.rsj_dmi_strategy加载失败，触发异常：

11:48:19 RQData数据接口初始化成功
历史数据更新中，进度23%，触发异常，是什么问题？如何解决？
解决了，在全局配置里面去掉rqdata的密码就能可以正常进行CTA回测。

打开CTA回测触发异常，rqdata流量限额，无法进行CTA回测，有没有什么办法继续进行CTA回测？

用print就行了，可以用run.py打开vnstation
run.py现在是在哪个文件夹里？用run.py打开vnstation的操作步骤是怎样的，请具体指点。
这是最好的答案，万分感谢。
C:\vnstudio\Lib\site-packages\vnpy_ctastrategy\strategies\atr_rsi_strategy.py在这里面加一句print(bar.datetime)，代码如下，请问，回测的时候要如何能看到这句的输出？
def on_bar(self, bar: BarData):
"""
Callback of new bar data update.

self.cancel_all()
print(bar.datetime)
am = self.am
am.update_bar(bar)

return新手入门，最重要的内容没有写出来，就是在策略的on_bar函数里交易逻辑中如何调试自己写的代码是不是想要的结果，能写这一个教程吗？
重置simnow的密码，试试。
楼主，按你的安装步骤，在刚装Ubuntu20.04系统下，vnpy2.1.3仍未安装成功。你是pip清华源还是默认官方下载安装模块？是否安装了anaconda3？翻墙否？

没有看到可以执行的vnpy 的configure文件。你的系统应该还是缺少一些模块。make install源码安装有时是挺折腾的，上次我装个模块， 折腾了好久，最后照着网上的一个建议，最后用了autoconf, autoreconf， 时间久了都忘了怎么折腾了。
你网上再搜索一下。 一般应该四步就装成功
你换一个目录，重新解压，然后再按照上面的正确步骤试一边。
