删除c:\users\administrator.vnstation目录再重启,就解决问题了
解决了，牛牛

我用的self.macd_macd[-1]不可以

各位好，哪里有最新的VC++可以下载，安装vnpy必须要VC++支持吗

我的另一台电脑正常使用，这台删掉c:\users\administrator.vntrader后还是无法打开，同样问题。难道是以前的pythons环境没卸载干净？

干货顶，国内的开发者和国外的开发者比起来其实还不是技术差距，可能还是开发规范性上，开源的把代码注释写的越详细，越有利于下一个版本的迭代出新

干货点赞

便于小白学习，感谢开源，希望有详细代码注释的版本出现

我安装了最新版，重启服务器后也出现了题主的类似问题，也按照上面的方法都试过了，即使重装后还是没解决问题。
具体情况如下：
VNSTATION可以正常登入，点击VN Trader Pro,出现配置页面，点击“启动”按键后，就没有反应了。

我们这是相同的问题，可能是电脑环境问题，我在另一台电脑可以正常打开。

谢谢，有包含全部代码的文件下载吗

你好，安装了vnstudio2.1.4，有vnstation的窗口，点击没有trader lite的窗口，其他窗口都可以打开，点击lite按钮的时候，提示如下：

出现了文章中同样的无法定位输入点问题，以前可以进vnstation，现在无法进入了，最后提示服务器当前无响应

vnstudio-2.0.6到vnstudio-2.1.6分别需要pyqt5哪个版本，是不是pyqt版本错了？

有vnstation的窗口，任务栏也可以看到，没有trader lite的窗口

C:\Users\Administrator>python -m vnstation

qt.network.ssl: QSslSocket: cannot call unresolved function SSL_set_psk_use_session_callback

加了还不行，不再维护的完全不可以使用了吗？

你好，没有找到我的答案，麻烦看看我的问题
