Automatic history check, download and refresh

Hi all,
I'm looking for a solution, maybe someone knows about something...

The ideal will be an EA that I can run everytime I open mt4.
The EA then automatically checks a provided list of instruments if all the data (M1 to H4 for example) is up to date.
The EA then downloads all new data from history center to make 100% sure all the historical data is up to date.
Lastly the data refreshes all the instruments (various timeframes) to make 100% sure every timeframe for every instrument (on selected list) is updated and refreshed.

I always need updated and refreshed data before I start running another EA and do analysis.

Kind Regards,
Peter

This script should do the trick.

Hi, thank you!
I will give it a go

Is it possible to define a list of the symbols to be checked and downloaded?
Can I assume this script will keep my data updated and also free from data gaps?

It gets data for the symbols in the market watch. It only gets the data your broker provides so if broker has corrupt data then guess what...

best would be if:
an EA checks all open Charts and than update only those opened ones.
Is that possible?
would be great
thanks for an info.

Nice suggestion

I have say about 32 symbols that I work with and need updated data always without gaps (due to missing history).
The data I use is at least 500 000 bars (where available) on M1, M5, M15, M30, H1, H4.
Sometimes I do not open MT4 for about 3 days, and when I run the EA or script it should check all the symbols in my pre-defined list, all the timeframes in list, and make sure the data I have is 100% and then download what is needed. Thereafter, a refresh of each chart and timeframe (maybe more than once to make sure gaps are removed).

I know it's a lot I'm asking for but this will be very practical for anyone who always needs accurate data that is always checked and updated when opening MT4 before running scans etc.

I have the same problem, I need to update the history automatically every new candle, with the previous script I have to do it by hand, does anyone have something for this?

I am looking for this kind of EA/script also, that it would refresh the charts for every new candle for all the pairs on market watch. Anyone got one?

cannot use that script, it says unsupported build, maybe someone have new working version?
