Please advise what are the possible causes of error 4806 when filling the indicator buffer from a handle which is not -1.

So far I have found variant with sleep after creation. In my case, I can give it a minute - all the same.

Sleep() should not be used in indicators. All indicators in a chart work in one thread. If you slow down one indicator, all of them will slow down.

For example, if you request timeseries data in OnInit(). I think it can also happen when the terminal is switched on at the moment of history swap.

It would be more correct to say that Sleep() does not work in indicators. Not at all.

Yes, that's right, I forgot. In general, try to write indicators as economically as possible!

I didn't specify - the indicator I'm talking about is in the EA. And in the terminal message window it is clear that the messages come after the time interval I have specified (I have arranged it so that after getting such an error the indicator tries to get the handle again and repeat all standard actions) with a delay after setting the handle. The indicator itself is a standard PivotPoints from the terminal set.

Why is the cloud network not working?

I have a terminal MT5 build 1241. How to update it? Won't my Expert Advisors and indicators disappear?

The latest versions are always available when you connect to MetaQuotes-Demo trading demo server.

Updates always restore all standard library codes. User files are not touched during updates. I also recommend using Storage(MQL5 Storage: Working with Storage - MetaEditor).
 
As of yesterday, the entire cloud network has been upgraded to new, more efficient protocols with tick history support.

To take advantage of this distributed computing network, you need to upgrade your terminal by connecting to the MetaQuotes-Demo server.
 

Sometimes in case of emergency shutdown (when the terminal was open), when you reopen it, this kind of perverse window of the tumblr appears and I don't remember how I managed to get it out last time (see picture). If you click on call of the glass in the upper left corner of the chart, the terminal just closes. Is there a file I need to delete where the configuration was saved at the time of the crash?
