Use #property tester_file "hello.csv" to transfer your file to tester agent.
You cannot open non-existing file with FILE_READ flag

After adding the code #property tester_file "hello.csv" to ea and putting file "hello.csv" into "...\MetaTrader 5\Tester\Agent-127.0.0.1-3000\MQL5\Files" directory before running,the result still give error and delete file automatically!

Hi Jianhua,

I have had to deal with similar situations. It might do you some good if you could show some of your code so we can better identify the problem...

Problem was solved in the service desk

You can open file with FILE_READ flag if this file exists. If file does not exist you cannot open it
