Hi,
Are you back-testing with the standard ‘MACD Sample’ EA to make sure everything is working?
Another thing to mention is that you are connected to your broker and will probably run into issues with your MT4 terminal overwriting HST data that comes from your broker rather than Tickstory.
P.S. Note also that the location of the HST and FXT files are different. Make sure you check the tester/history directory that all the FXT files are there.
