TestGenerator: write file error

 

Dear experienced traders


Do you know what is "TestGenerator: write file error"?

When I run test 2012~2020, the "TestGenerator: write file error" will happen. 

But when I separate test as 2012~2013, 2013~2014, it will work well. 



Thank you in advance and best wishes,

Sky
