我也遇到同样的问题,但我直接用实盘去连接,为什么也是这样呢?
如果是期货公司还没有升级到穿透式管理,那么在代码里面如果注释掉穿透式监管的相关功能?

我做美股指期货,也是在弄盈透的api

感谢答复,防火墙一直是关闭状态.TWS配置,貌似也没有找到相关的设置.不知还需要如何配置?

另外订阅合约的时候,CME的迷你纳斯达克指数期货 合约代码 在盈透上显示NQ jun21'19@globex .在VNPY上订阅时不知道应该怎么输入合约代码?
尝试过几次,之后的几次没有再遇到主题上的报错,但输入代码后回车都没有出现行情,同时windows任务管理器上发现python进程的cpu占比暴涨上升到18-20%幅度.感觉回车之后内部的确是在运行一些代码,只是没有报错也没有反馈. 这下就不知道怎么搞了.请指导
谢谢大佬.
