Asynchronous loading of charts - does MetaQuotes really know how many problems this creates?

Yes I think this would be the best method. But as mentioned, it happens rarely and it seems that it happens on specific dates, cause it´s like that, that I do not hear nothing from any client for a while, but then there are several clients within 2-3 days. It does not necessarily mean, that it does not happen every day at someones computer. This timing could be broker-server related, actually I can only guess here, but in fact its not a broker-server problem, we checked this simultaneously of course couple of times when there were more problems as usual. It seem to happen locally.
I start a test on 20 charts, set with 1000 bars max, build 2470, Metaquotes-Demo server. I can let this test run as much time as needed.
If needed I can run it on an other broker or more charts.
Thx for you effort. I mentioned somewhere earlier that I am not sure if this happens with demo accounts as well. Maybe it makes sense that I give you a new hint when there are some new mails in the support mailbox, which could be caused by this issue. Currently its totally quiet.
Ok, I will run it on a live account, not a problem.
After 10 days running it on a live account, nothing happened, I gave up. There is obviously something else at work to reproduce the problem.
Thank you for your effort. I also had no such issues at the support desk since we started this conversation.
This is the same bug I meet when I test the data of a lot of symbols in my routine placed in a OnTimer call.
In random case during calls to iClose or iOpen function the sytem freeze and waits for a long. long time!
In Debugging mode I saw that the data returned is zero but you understand that is not right wait for a such long time. I would prefer set a query timeout value so that I can jump over the problematic symbols.
