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

Thank you, I'll give it a try!
Add a "RefreshRates();" after ResetLastError to make sure it updates
