SwInGeR:
Can you tell me why there is no possibility to download Experts? I cannot even download the demo or free versions. I press "download" and nothing happens, I checked in Chrome and IE.

Can't download from Codebase or Market? The Market is not fully up and running yet - just getting ready, but Codebase is downloading fine.

If you work through proxy, check if you have proxy settings in Internet Explorer.

Through Market (both from program and browser), from CodeBase is downloading.

Here's what I found in the Anglian help.

ENUM_CHART_PROPERTY_DOUBLE

ID	Description	Property Type
CHART_SHIFT_SIZE	The size of the zero bar indent from the right border in percents	double (from 10 to 50 percents)
CHART_FIXED_MAX	Fixed chart maximum	double
CHART_FIXED_MIN	Fixed chart minimum	double
CHART_POINTS_PER_BAR	Scale in points per bar	double
CHART_PRICE_MIN	Chart maximum	double r/o modifier - subwindow number
CHART_PRICE_MAX	Chart minimum	double r/o modifier - subwindow number

To the developers.

Here's the Anglican reference.

What exactly is the question? https://www.mql5.com/ru/docs/constants/chartconstants/enum_chart_property#enum_chart_property_double

[---]

CHART_PRICE_MIN	Chart maximum
CHART_PRICE_MAX	Chart minimum

sergeev:

CHART_PRICE_MIN	Chart maximum
CHART_PRICE_MAX	Chart minimum

Very interesting.... Thanks, we will check other languages too.

Please tell me in a nutshell what command to close an order with. Or give me a link to an article. I don't need any complicated code, just a couple of lines.

In MT5, we do not open and close orders but positions. To close an open position, you should send a trade request to open an opposite position with the same volume. See MQL5 Reference Guide / Standard constants, enumerations and structures / Data structures / Structure of a trade request

On October 20, I downloaded MQL5 Strategy Tester Agent from cloud.mql5.com. With the default setting of the number of agents on a single-processor computer, 2 agents have been created, and in the configurator on the Services tab, the number of recommended agents to install and set is 1. The build at installation was 507, updated to 523.

Good night . I've just started to look into it closely. It seems to be an obvious bug. I cite the code below, if I comment on one line below (it is marked) then it seems to work - I do not understand what the problem is. The situation can be avoided by specifying an explicit size for the Raznica[] array. I did not find anything in the documentation on this subject.
