Renat, I've been shy to ask: How is the OpenCL device rating calculated?

2013.08.23 09:31:23 OpenCL Device #1: AuthenticAMD AMD Phenom(tm) II X6 1100T Processor with OpenCL 1.1 CPU (6 units, 3840 MHz, 16345 Mb, version 2.0, rating 17)
2013.08.23 09:31:23 OpenCL Device #0: GPU Advanced Micro Devices, Inc. Cayman with OpenCL 1.1 (20 units, 750 MHz, 1024 Mb, version CAL 1.4.1703 (VM), rating 171)

What is taken as a unit of measurement?

Test run time on the device, the lower it is, the higher the rating is.
And unfortunately, the test run time depends on the system load at the time of its execution.

The terminal, in order not to run this test all the time, caches its results in the registry.
If "OpenCL" value is deleted from HKEY_CURRENT_USER\Software\MetaQuotes Software (or the same path in HKEY_LOCAL_MACHINE), the terminal will re-run the test.

The same device test is performed when the terminal or OpenCL drivers are updated.

MetaDriver:
You need to install an OpenCL driver. Somewhere there's an article on how to install OpenCL drivers on your computer. Look it up, you can easily find it in the articles.

Found it, thank you. Now I just need to figure out how to put it all to work.

Looks like I screwed up with the processor as it refused to install on my OS (I have Win XP x64).

I will probably only be able to use the OpenCL CPU on my laptop.

The terminal caches the test results in the registry to avoid running this test continuously.

The same test is performed when terminal or OpenCL drivers are updated.

Thank you, Ilyas.

Is it possible to make it so that after optimization in "Optimization" tab along with standard parameters (like Result, Profit, Recovery Factor, etc.) I can insert my custom parameter. For example, I want to immediately calculate Parametr = Profit / Draw Down% (Parametr = Profit / Draw Down%) for each run, and have an additional column with this parameter. If it's possible, please send me a link where it's described how I can do it.

I can't understand : after running the EA in the tester, after pressing the stop button the whole price chart window is coloured white - it turns out to be 256 indicator windows, which are hanged on the window. I can not find an error in the code. Can anyone help?

[Stanislav Korotky]

There's been information about a similar problem (supposedly a bug), but the suggested solution doesn't work for me. The situation is as follows. I have a singleton class:

class Profiler
{
  private:
    static Profiler *pSingleton;
...

This compiled before without any problems. Now the following error occurs: unresolved static variable 'Profiler::pSingleton'.

To workaround the bug I suggested that the variable be initialized explicitly. I'm writing it:

Profiler *Profiler::pSingleton = NULL;

The error persists.

How to fight it?

I will take it to the 4ks forum. If this is an EA then why is there a #property indicator_chart_window in the code, which is for the indicator.

Try the following:

static Profiler *Profiler::pSingleton = NULL;

Try it this way:

I already tried that. Same thing.
