Constant high load on the CPU core.


 

The visualization of trading sessions is almost invisible.

Constant high load on the CPU core.


Low CPU load on my system with the indicator loaded on 4 charts:

I also tried increasing "Number of days to display" from default 35 to 100 on the 4 charts, switching timeframes frequently, yet the CPU load is low.

I also tried resizing the y (price) axis and  zooming in/out to test "CHARTEVENT_CHART_CHANGE" event and yet CPU usage does not exceed 1%.

Edit:

I used the Profiler and compiled the indicator with/without optimizations -> I failed to spot major bottlenecks in the code

Incorrectly determined the time offset.


I tried this code.


Result.

I would be grateful if you find a broker with weird configuration of the chart bars thus giving wrong GMT offset.

It is a MT5 issue, just resize the price axis by holding down the left mouse button and drag down.

It's probably better to make a solution that doesn't require these steps.

I already tried 6 other servers in addition to RannForex. Low CPU load on all servers.
1. ICMarkets
2. OctaForex
3. AdmiralMarkets
4. Exness
5. XMGlobal
6. RannForex
When I am on my PC, I will re try with your sample code.
