Note
To use the WebRequest() function, add server addresses to the list of allowed URLs in the "Advisors" tab of the "Settings" window. The server port is selected automatically based on the specified protocol - 80 for "http://" and 443 for "https://".
The WebRequest() function is synchronous, which means that it pauses execution of the programme and waits for a response from the requested server. Since delays in receiving a response to the sent request can be long, the function is prohibited for calls from indicators, because indicators work in a single thread common for all indicators and charts on a given symbol. Delaying the execution of an indicator on one of the charts of a symbol can cause stopping the update of all charts on this symbol.
The function can be called only from Expert Advisors and scripts, as they work in their own thread of execution. When called from the indicator, GetLastError() will return error 4014 - "System function is not allowed to be called".

I'm not questioning your assertion in any way,
but let me ask you to give an example of the data,
that are in the "data window", but cannot be accessed from an indicator or an Expert Advisor.
