Moving Averange in array

[donato]

Good morning

I'm a newbie in mql4 and i still don't  understand how put value of moving averange in array. I get always some errors (like array out of range) 

I just need and alert when the value of moving averange in the previous candle is more high then actual candle in OnCalculate process.

Can someone make me this little piece of code?

however thank you

You need to read about the usage of arrays and the examples

Where i wrong?

 double clos[500];

   for(int k=0;k<500;k++)

   {

      clos[k]=iMAOnArray(clos,0,period,0,method,1);

   }

    ArraySetAsSeries(clos,true);

Alert(clos[0]); 

 (period = 12 and method = MODE_SMA)

The alert say me that clos[0] has 0.0 value.

I just want the last value of moving averange

1. Set the array as series before populating it.

2. clos[k]=iMAOnArray(clos,0,period,0,method,1);

   What average do you think you are calculating?

1. thank you

2.  Simple averange with 12 period or i'm wronging?

Simple average of what? clos has no values. If it does you then clobber the array by assigning the iMA to it so subsequent iMAs are meaningless.
