EA / Strategy Tester data : M1 historical data from IG lost on the FRA40. HELP!
Thanks but I prefer the Stones! Of course, if you had a slightly more constructive answer to offer me, of course, I would be ready to listen to The Beatles, even through a parody.
Only Jesus saves, we [normal people] have to do Backups ;)
Sorry to tell the truth, but.. There is no way to go back to "Yesterday" unless we have at least 3 or more backups of important data.
Do you have any other machine, on your local network, that was once used by the Strategy Tester? (by sharing processor to speed up the strategy tester?)
If you do, that machine may have a copy of that history on its HDD.

In fact, I had no idea that the histories were saved locally by MT4 and foolishly thought they were downloaded from the IG server when needed.
I run MT4 on Parallels virtual machines under MacOS and my backups are provided by the Time Machine. Unfortunately, the Time Machine was configured not to back up virtual machines.
I regularly backed up MT4 directories which seemed sensitive to me (see screenshot below for illustration) but, unaware that they could not be reconstituted via the data of the servers, the histories were not part of them!
Anyway, thank you for your response. But I'm starting to believe that my cause is hopeless ...
Have you tried this trick? https://www.mql5.com/en/forum/124619#comment_3253773
It might work (or might not). Try it! Maybe you will get lucky!

I also use Metatrader on Parallels, and I don't make Timemachines backups of the WindowsVM.. just MacOS full backups, excluding the VM.
But every weekend, I copy the VM file manually to an external HD, and I keep 5 older copies of it there.
The reason is that Time Machines backups for Parallels works strange, I suppose most users disable backups for the Parallels VM
But being disabled, its very easy to manually backup the complete VM as it is just 1 directory package, so just coping the VM package to another partition, or external HD, guarantees it in case of problems.. just put the old package back and Parallels will boot it, and it will be exactely as the day you copied it externally.. including all files, etc..
It is a good and easy routine for you to do from now to future, to copy manualy the VM package every weekend.
I started to do it, since I lost my Parallels VM 4 years ago when I tried to use a pirated parallels newer version, and it messed up my VM package, which never more booted again.. Made me lost lots of source code since I was starting to learn how to delelop on MQL4 (4 years ago)..
Since then, no pirated parallels anymore, and just in case, I began to make backups of the VM file. As an aditional guarantee.
I whish you good luck on solving your situation. If there was any other way for me to help you, be sure I would be helping.
I will take a look at my servers on my localnetwork. Sometimes I activated them to sell processing to the MQL Cloud..
And for testing on the cloud, Strategy tester transfer to my servers the full history which is being tested by the EA of someone arround the world which is using my machines processors..
I dont delete any history since the HDD is huge.. and history from several brokers exists there. (it keeps an organized directory structure [broker -> symbo' -> date ->history files)
I will take a look on them, (it is a total of 6 servers), to check if one of them contains history from IG-LIVE or IG-DEMO, and for which symbols they may exist.
PS: if you manage to know someone who has being selling processing for the MQL Cloud for a long time, there is a high probability that they may have the history you need. As long as the owner don't delete history by routine. Everyone who sells processing to the cloud are the most close people to have the luck of having those histories files

Hello,
Following an OS reinstallation and a failed backup, I lost the M1 history on the FRA40 that I had in MT4 from IG-LIVE and IG-DEMO servers.
I had a full history recorded locally since 2017 but now I only have a ridiculous depth until 2021.07.01, which is totally insufficient to use the Strategy Tester in a serious way to test an EA.
Unfortunately, IG does not allow these customers to download this history in order to reconstruct it locally for MT4. After contacting tech support, they told me they couldn't do anything for me and invited me to get this data from a third-party vendor.
My problem is that the data found with other suppliers does not include the IG "off-market" quotation ranges from 10 p.m. to 8 a.m. (local time) and is therefore not suitable as a substitute for IG data ( 24/24 quotation).
Does anyone have a history of the FRA40 24/24 in M1 (1 minute) to help me out? Otherwise, do you know from which data provider I could find what I'm looking for?
Thank you to those who will answer me.
