Ma on array on EA

So I'm trying to create a filter in which the STDEV should be smaller than the MA on array.
I mean, i can just drag it into it on mtf, but it is for an expert.
this is what i got:

y = iBarShift(NULL,1,Time[0]);
double sdev = iStdDev(NULL,0,100,0,0,0,y);

sdevarray[y] = sdev;


double marray = iMAOnArray(sdevarray,0,1000,0,MODE_SMA,y);

later i just use a condition like "if (sdev < marray)" and so on.

it doesnt work "integer expression expected" for the y.

Can anyone help?

int y=iBarShift(NULL,1,Time[0]);

There are other issues though ,this will produce an array out of range error on execution

The M1 bar is requested with iBarShift

but in StdDev the CurrentTimeframe is sent .

You must also check if the bar is found
and you can specify if you want the exact bar or the closest available
