_Digits The _Digits variable stores number of digits after a decimal point, which defines the price accuracy of the symbol of the current chart.
You may also use the Digits() function.
_Point The _Point variable contains the point size of the current symbol in the quote currency. You may also use the Point() function.
_LastError The _LastError variable contains code of the last error, that occurred during the mql4-program run. Its value can be reset to zero by ResetLastError().
To obtain the code of the last error, you may also use the GetLastError() function.
_Period The _Period variable contains the value of the timeframe of the current chart. Also you may use the Period() function.
_RandomSeed Variable for storing the current state when generating pseudo-random integers. _RandomSeed changes its value when calling MathRand(). Use MathSrand() to set the required initial condition.
_StopFlag The _StopFlag variable contains the flag of the mql4-program stop. When the client terminal is trying to stop the program, it sets the _StopFlag variable to true.
_Symbol The _Symbol variable contains the symbol name of the current chart.You may also use the Symbol() function.
_UninitReason The _UninitReason variable contains the code of the program uninitialization reason.Usually, this code is obtained by UninitializeReason()the function.
You may also use the Digits() function.
_Point The _Point variable contains the point size of the current symbol in the quote currency. You may also use the Point() function.
_LastError The _LastError variable contains code of the last error, that occurred during the mql4-program run. Its value can be reset to zero by ResetLastError().
To obtain the code of the last error, you may also use the GetLastError() function.
_Period The _Period variable contains the value of the timeframe of the current chart. Also you may use the Period() function.

_Symbol The _Symbol variable contains the symbol name of the current chart.You may also use the Symbol() function.
_UninitReason The _UninitReason variable contains the code of the program uninitialization reason.Usually, this code is obtained by UninitializeReason()the function.
