Tickstory

So if my modelling quality is 99%, does that always mean that the test was executed properly? With a 99% result, is there still the possibility that something went wrong?

Thanks for the quick response. I have another related question. I noticed that one of my data files (15-min) has a smaller size (see screenshot). I ran some backtesting using 15-min data. Was the original data overwritten by MT4? Do I need to redownload the data? I thought I changed the permissions ...

I have installed Tickstory and downloaded tick data. I have also opened MT4 from within MT4 but when I run my EA, I get a read only error. I made the data folder "read only" but I get the error. Please let me know what I need to do. Thanks.
