Solutions for forcing 100% history data download?

In eight years of trading on the MT4 platform I've only run into serious history download problems three times. Two of those times are currently with two different brokers, one in New Zealand, and one in Australia. From 28 pairs, 75% of the time chart data is missing on a new chart. One support technician said it was a Metaquotes problem and a manual solution was to; a.) choose the 4H chart on each pair, b.) hold down the "Page Down" key, and, c.) then scroll back several months. Then repeat for every time chart for which I needed history data. For one indicator I use, I need history data for several chart times on each pair, and the manual solution is slow going.

I've tried using several different history download scripts to force download, but they get hung up and don't complete the task. So I'm now manually going through every chart using the manual technique mentioned.

Has anyone else run into this problem recently? Is it due to a glitch in the current MT4 version or the Metaquotes servers?

Has any one found a solution or run across a script that handles the current Mt4 version and provides a forced download ?

Thanks.

reference of the .hst file

http://forum.mql4.com/60455

save all your history in another folder

you must open each .hst file with a programming language
you keep the header
you write only one arbitrary bar with a date unix time year 2000 for example
you close the file

now if you open metatrader
it should load all the history available in the server

Felixis, Wow, thanks for your reply but I'm sorry that I don't know how to implement the procedure you describe?? Could you elaborate, or perhaps anyone else that understands the solution Felix describes?
Thanks

@felixis: i am just elaborating on your described method (which works fantastically) for (my) future reference.

Skills required: Knowing how to use Hex Editor (recommended: HxD)
Reference: https://www.mql5.com/en/forum/149178

 

1. find .hst in <TerminalPath>\history\<AccountServer>\<SYMBOL><TIMEFRAME>.hst
2. if you don't have one that you want, use Tool>History Centre><SYMBOL>><TIMEFRAME> and download something first to make the file exist
3. open file in HxD
4. locate header (first 148 bytes (read the reference))
5. locate first "row" of data (next 60 bytes)
6. select the rest of the data
7. delete them
8. select first 8 bytes of data, set it to 0000000080436d38 (that's little endian, epoch time, 2000-01-01Z00:00:00)
9. make everything else 00
10. save the file
11. restart Metatrader Terminal
12. goto Tool>History Centre><SYMBOL>><TIMEFRAME> and download entire history

Please correct me if i didn't accurately describe a step. Thanks!
