Fundamental analysis with indicator problem

 

Hi, i have got the fundamental data on a CSV file, and i have brought this data into an indicator, and the indicator is working well in the real time. However when i want to use this indicator in a simple expert and test it in previous time, it gives an error that the indicator can’t open the file [ERR_CANNOT_OPEN_FILE (4103)]. Although the indicator is working properly in my real time I can’t use it in optimization.

I would appreciate if anyone could help me solve this problem and I could use my fundamental indicator in Expert Advisor.

tnx

 
did you copy the file from <terminal>\experts\files to <terminal>\tester\files for testing?
