The Latest version of the Metatrader 5 loses the candles suddenly. I guess there is issue with the Symbol. Even I have faced the same issue with custom symbol. But this time it is also with the in-build symbols.
Have a look at the image:
You see that the candles started from the very beginning.
When I close the Metatrader 5 and restart, everything works fine. But after sometime it happens again. It happened with me 5 to 6 times till now.
Please take a note of this.
I got this log after I refresh the graph:
