Deleted data in MT4 upon opening terminal...?

I have a question regarding the disappearance of data on random occasions within my "demo" account with MT4.


For starters, I have been using the MT4 platform for years only as a visualization tool for my trading (I would never use it or its mainstream brokers to execute my trades). Because I use a demo account, I must periodically re-register for a new demo account since my "unlimited and never-expiring" account is eventually cut-off by these brokers.

When that happens, I re-load a new MT4 platform and I must manually copy/paste both my "profiles" and "history" folders into the new downloaded platform in order to be able to see and manipulate data-bars going back as far as my old platforms.

On the current downloaded MT4 platform I am using, I have just opened it and noticed that somehow/some way, my data-bars only go back roughly 8 months - (the previous 4 years have somehow magically disappeared) - and I am curious to know how this could have happened.

I then tried to again manually copy/paste my "profiles/history" folders from older versions and it has not seemed to work.

Any idea what has happened this time? -Many thanks.

This happens because the account is renamed. For example gomarkets has two servers. One original and another titled 'demo'. In the MT folder these servers have separate histories, profiles and data. I forgot my hack but it could be as simple as copying files to the other directory.

**As an update to this problem...**


Although I know there are multiple servers/account feeds that can come from these MT4 brokers, I am really not sure why this has affected the problem, because I have been opening my platform the same way for years. I do not change any server-feeds or any other settings. I simply clik the MT icon and the platform will update with my historical data normally still there.

I have tried, once again, to go into my "current" platform (demo account) and to copy/paste my old history from my past account - to no avail. This used to work and for some reason it now doesn't.

I then tried to get cute with my most previous saved MT4 folder (the account that was most recently shut down and for which I had historical data) and I opened it and entered my current username/password. When the platform updated, it has now cause the same problem even with this older platform and my historical data has been erased!!

When I try to go to the history center and try to import data from a filed I had saved in the past, nothing works. So now I have no way of seeing my past data while my "re-signing in" has seemed to delete everything.

I would appreciate if anyone could help me to trouble shoot this most frustrating issue...

*Back again*



I just opened my MT4 platform and now all of my notes and annotations have been erased Can anyone tell me why this might be happening?


I had to download yet another "demo" account just last weekend after being cut off, and copied my old "profile" into the new platform folder. Ironically, my other annotations that were in the old profile still show up - But everything that I have added since the new download have disappeared. I "save profile" everyday in order to save all my work (for the past years) - so what can be going on?? Why is MT4 so fickle sometimes, or is all this related to the brokers?
