MQL5 bug when working with iClose/iOpen timeseries access, etc. - page 6

I did catch iTime hanging up on PERIOD_M1.


My system:

has ceased to give the current open time of a bar on M1, and all the time gives the last time before the connection is broken.

Maybe it's a static array

datetime CM1_T[1];

And need to use a dynamic array?


Added: replaced CM1_T[1] with a dynamic CM1_T[]. After forcibly breaking the connection for about three minutes, the string

CopyTime(_Symbol,PERIOD_M1,0,1,CM1_T)

Outputs the last known time with M1 before breaking the link.

Try to put it on M30, and get data from M30 as well. That's exactly how it freezes, which is shown in the video. Switching the timeframe doesn't help, only removing the indicator and then installing it.

I confirm that playing with the reloading of the indicator is not 100% helpful, so to say that for every 3 times I manage to reload the indicator completely and of course not to guess by coffee grounds, it's easier to unload the indicator and reload it on the tool.

But it's a hell of a thing, what kind of trading automation can we talk about in this kind of dancing with tambourines.

 
Vladimir Karputov:

*** Maybe it's the static array

I have dynamic arrays, as it's originally written that it's better to use them at SoruXXX, the problem is not the type of array.

 
You know, at work, I have to write a lot to technical support of different companies (Symantec, DeviceLock, Kaspersky, FortiNet, Xspider, etc.), but never before I had to find the cause of the problem described by me, mda .... There remains only to write myself a fix :)
 
Farkhat Guzairov:

... but unfortunately, the MQ product, has been my focus for about 10 years.

in another 10 years everything will be working properly )))))))))))))))))))))

 
I had a similar problem about six months ago. I was writing an arbitrage robot, so I was working with a large list of characters at the same time. I was writing an arbitrage robot, so I was working with a big list of symbols at the same time. The robot was protected from working with outdated quotes, so the problem was only a decrease in activity. The only thing that helped was re-attaching the EA to the chart.
 
We will reproduce and correct.
 
Renat Fatkhullin:

How soon can we expect a correction?

 
Farkhat Guzairov:

The freezing of alien invisible timeframe update after reconnect has been dealt with and fixed. The reason was wrong cache statuses after the reconnect.
