I already posted a question : what are the exact names of the custom indicators you wish to use in calculation (I mean, they are not called "indicator1", "indicator2" and "indicator3", aren't they)?

You have to replace that names with the exact names of the indicators you wish to use in a iCustom() call, or else it will do nothing. Also, your start function should look like this (again, you have to replace the names with real names) :

int start()

{

if(Bars<=1) return(0);

int ExtCountedBars=IndicatorCounted();

if (ExtCountedBars<0) return(-1);

if (ExtCountedBars>0) ExtCountedBars--;

int pos=Bars-1;

if(ExtCountedBars>1) pos=Bars-ExtCountedBars-1;

while(pos>=0)

{

ExtMapBuffer1[pos] = (iCustom(NULL,0,"indicator1",length,0,pos)+

iCustom(NULL,0,"indicator2",length,0,pos)+

iCustom(NULL,0,"indicator3",length,0,pos))/3.0;

}

return(0);

}

Thank's Mladen, The exact name is "indicator1" for the first indicator ,"indicator2"for the second and finally " indicator3" for the final. This what you want ?

Thanks Mladen for your quick reply,

it don't work,

i thinks the start fonction is not good

Can you post an exemple of 3 custom indicator ?

bixwind,

I do not know what do the "indicator1", "indicator2" and "indicator3" do. Made these that actually only calculate a moving average and used them in the _test indicator (that does that median calculation you started from) and it works OK (see how it looks on the terminal). So if the parameters for your custom indicators are OK, it should work OK, since the test indicator works OK too

This one will do that. You can specify various properties of the time-symbol label using parameters
