New Custom Moving Average Indicator

 
I need a Moving Average Indicator source code that has Applied_Price variable.
The "Moving Averages.mq4" indicator in the Custom Indicators folder has three variables, but not Applied_Price variable:

extern int MA_Period=13;
extern int MA_Shift=0;
extern int MA_Method=0;



Is it possible to have the source code to the "Moving Average.ex4" file in the Indicator folder, or a Moving Average indicator with these 4 variables?

extern int MA_Period=13;
extern int MA_Shift=0;
extern int MA_Method=0;
extern int MA_Price=0;



Thank you in advance,
Wackena
