MT5 updates chart slowly

[marketcycle17]

Hi

I use MT5 and I noticed the chart doesn't update on every price change. Sometimes it can take up to 30 seconds, the time varies, sometimes takes a few seconds, and sometimes it updates normally as it should.

Have tested it on IC Markets and MetaQuotes, still same result. Both demo accounts, maybe that's the problem? If not, what is causing this and how can I solve it?

I have checked this on low and high timeframes.

CPU-usage seems normal.

Maybe it's not a problem because if price doesn't move then there is no reason to update. I compared with charts from other free sources and it's the same result.

But my problem in this case is that I use a timer and it seems to update only if price updates. I am using this one: https://www.mql5.com/en/code/20185
