ErrorDesc:
The code is based on the ErrorDescription library.
Library contains ErrorDescription() function with two input parameters error_code and optional parameter txt_prefix.
GetLastError() return codes can be found here https://www.mql5.com/en/docs/constants/errorswarnings/errorcodes.
OrderSend() function's retcode field values can be found in https://www.mql5.com/en/docs/constants/errorswarnings/enum_trade_return_codes.
Both tables are included in ErrorDescription() function.
LibraryTest.mq5 script can be used to check description of a known error code. Just execute script with an input error_value set to error code and it will print description. If error_value is set to -1 script will print all available error codes.
