indicator doesn't draw when the charts are loading

[Pedro Taveira]

Hi,

I have a recurring problem that happens on my MT5 indicators.
When I open a new chart and attach the indicator to the chart, the history is sometimes still loading.
That also happens when I change the time frame of the chart.
When this situation occurs the indicators don't draw anything. On a separate window indicator I only see a blank screen.
Then I have to refresh the charts, or change time frame again for the indicator to draw.

I don't know if this has anything to do by MT5 be an asynchronous platform.
I already tried to find for solutions but didn't reach any that works.

I even tried to use the script on this page but with no success:
https://www.mql5.com/en/docs/series/timeseries_access
The script always returns "Already available data in timeseries are enough"
But the indicator still doesn't load properly.
I tried to put the script running also onTick, and not just onInit, just to say what does it output.
But on all ticks it returns the same message, although I see the charts still loading new history and the indicator doesn't draw until I refresh it.

Do you also get this "problem"? How can I fix this?

Thanks.
Pedro
