Historical Data Import & BackTest

 

hi, I am on FXCM MT4 platform.

I am wondering how can i import my own historical data into FXCM MT4 platform and conduct backtest based on these datas. I tried historical center / import, but when i hit "import", nothing happened and how can I check the data has been successfully imported? where is the local file? 

This topic seems old to many, but I tried searching online, no convincing instruction. Appreciated.
