  • 好的 我们排查下 ,若能分享策略或者部分策略 ,我们能复现就更好了
  • 是因为你订阅1分钟k线的时候,订阅 方法 写错了,应该这么 写: ``` context.subscribe_bar(context.instruments,'1m') ``` \
  • 参考这个链接:建议日志不要输出 太多,否则前端界面会卡死 [https://bigquant.com/experimentshare/0711774931e441a0a4511100176f4775](https://bigquant.com/experimentshare/0711774931e441a0a4511100176f4775) \
