I want to create this moving average

Value1 =
+0.4360409450*Close[0]
+0.3658689069*Close[1]
+0.2460452079*Close[2]
+0.1104506886*Close[3]
-0.0054034585*Close[4]
-0.0760367731*Close[5]
-0.0933058722*Close[6]
-0.0670110374*Close[7]
-0.0190795053*Close[8]
+0.0259609206*Close[9]
+0.0502044896*Close[10]
+0.0477818607*Close[11]
+0.0249252327*Close[12]
-0.0047706151*Close[13]
-0.0272432537*Close[14]
-0.0338917071*Close[15]
-0.0244141482*Close[16]
-0.0055774838*Close[17]
+0.0128149838*Close[18]
+0.0226522218*Close[19]
+0.0208778257*Close[20]
+0.0100299086*Close[21]
-0.0036771622*Close[22]
-0.0136744850*Close[23]
-0.0160483392*Close[24]
-0.0108597376*Close[25]
-0.0016060704*Close[26]
+0.0069480557*Close[27]
+0.0110573605*Close[28]
+0.0095711419*Close[29]
+0.0040444064*Close[30]
-0.0023824623*Close[31]
-0.0067093714*Close[32]
-0.0072003400*Close[33]
-0.0047717710*Close[34]
+0.0005541115*Close[35]
+0.0007860160*Close[36]
+0.0130129076*Close[37]
+0.0040364019*Close[38];

Close[0] is the close today
Close[30] is the close 30 days ago

Thanks

Just before your equation add the lines shown below which will create the necessary array and perform a null check.
Then all you need to do is return Value1 to the chart
Alex

var Close = getValue("Close",0,-39);
if(Close[38]==null) return;

Hi Alex i've write this
It doesn't work...where are my errors ?
Also I want the mov average to be on my price bars


{function preMain()
setPriceStudy(true);
setStudyTitle("FAST");
setCursorLabelName("FAST", 0);
setDefaultBarFgColor(Color.black, 0);
}
{function main
var Close = getValue("Close",0,-39);
if(Close[38]==null)
return;
var Value1 = +0.4360409450*Close[0] +0.3658689069*Close[1] +0.2460452079*Close[2] +0.1104506886*Close[3] -0.0054034585*Close[4] -0.0760367731*Close[5] -0.0933058722*Close[6] -0.0670110374*Close[7] -0.0190795053*Close[8] +0.0259609206*Close[9] +0.0502044896*Close[10] +0.0477818607*Close[11] +0.0249252327*Close[12] -0.0047706151*Close[13] -0.0272432537*Close[14] -0.0338917071*Close[15] -0.0244141482*Close[16] -0.0055774838*Close[17] +0.0128149838*Close[18] +0.0226522218*Close[19] +0.0208778257*Close[20] +0.0100299086*Close[21] -0.0036771622*Close[22] -0.0136744850*Close[23] -0.0160483392*Close[24] -0.0108597376*Close[25] -0.0016060704*Close[26] +0.0069480557*Close[27] +0.0110573605*Close[28] +0.0095711419*Close[29] +0.0040444064*Close[30] -0.0023824623*Close[31] -0.0067093714*Close[32] -0.0072003400*Close[33] -0.0047717710*Close[34] +0.0005541115*Close[35] +0.0007860160*Close[36] +0.0130129076*Close[37] +0.0040364019*Close[38]);
return Value1
}

You have the open bracket ie { in the wrong location in both function preMain and function main. The open bracket should be after the function and the parenthesis ie function preMain(){ and not before.
Also in function main you omitted to include the parenthesis () ie function main()
