照上面步骤，为什么出来上面的错误呢？

on_trade下写个print(trade.datetime)就行啊
可以了，谢谢！

如题，能否把回测时的Log导到本地，或能保存下来？本目靠powershell run.py进去能看到运行的打印，但回测时间一长，很多打印都没了，有什么方法把这些打印数据都保存下来呢？

vnpy有没有详细的开发文档呢？没有文档查起来好慢啊！
目前想回测时，打印订单成交的时间，请大神支招！！

大佬，该问题解决了吗？

请教在苹果mac os上面macd图的比例缩放似乎不对，绿柱完全没有，红柱显示一小部分，快慢线经常跑出范围，大概是什么地方出了问题？

我回入回测K线图后，也有同样的问题。我看到高度范围一直是0-1，应该是显示范围不对，不知道在什么地方改？

原码的路径：\vnstudio\Lib\site-packages\vnpy

有申请了SIMNOW帐号，服务器也显示连接正常了，但就是查询不到数据，看原码里面都只有init文件，这是正常的么？该怎么处理？
