Importing Back-test Data in Metatrader4
Part 1 – Clearing Out Old History Data
1. Open up the folder in Windows Explorer by going to File | Open Data Folder
2. Now close down Mt4 (but leave Windows Explorer open)
3. Now to delete all the data for EURUSD say, navigate down to the appropriate files and delete all the EURUSD*.hst files.
Part 2 – Importing Your Own Data
The next thing to do is to import your own data. You do this by clicking the Import button and then navigating to the file that you want to import. Once you’ve imported your own data, Mt4 won’t overwrite it, but it will still add stuff beyond the end of your data. There’s not a lot you can do about this but as long as you know what date your data goes up to and are careful only to test up to that point then it should be OK. You should now have your own imported data in the list.
You should now see your data in the dialog box. Finally to make sure that it’s saved to the history folder you should close down Mt4.
