Help to improve it, please

[Barros]

Please, can someone help me?
I would like to put the texts BUY and SELL, and sound alerts, when the formula make changes in colors:

function preMain()
{
setStudyTitle("Movtrend");
setCursorLabelName("Movtrend", 0);
setDefaultBarFgColor(Color.white, 0);
setPlotType(PLOTTYPE_INSTANTCOLORLINE);
setDefaultBarThickness(4, 0);
setPriceStudy(true);

}

var wt = null;
var wt_1 = null;

function main(n) {

if(n == null)
n = 34;
var sum = 0;
var i = 0;

if(getBarState()==BARSTATE_NEWBAR){
wt_1 = wt;
}

for(i = n; i > 0; i--)
sum += (i - (n + 1) / 3) * close(i - n);
wt = 6 / (n * (n + 1)) * sum;

if(wt>wt_1){
setBarFgColor(Color.lime);
setPriceBarColor(Color.navy);
}
if(wt<wt_1){
setBarFgColor(Color.purple);
setPriceBarColor(Color.red);
}


return wt;
}

Please, I would like to know if some Moderator can help to improve the formula or if I asked something wrong.
Thanks.

To add the text the easiest solution is to use the same efs I modified for you a couple of years ago (see this thread) and replace the following section of code which identifies the points in which the plot changes color and paints the background

if(wt_1<wt_2&&wt>wt_1)
    setBarBgColor(Color.lime);
    
    if(wt_1>wt_2&&wt<wt_1)
    setBarBgColor(Color.yellow); 

with the following code

if(wt_1<wt_2&&wt>wt_1){
        drawTextRelative(-1, AboveBar1, "Buy", Color.blue, null, Text.PRESET|Text.CENTER, "Arial", 11, "Buy"+rawtime());
    }else{
        removeText("Buy"+rawtime());
    }
        
    if(wt_1>wt_2&&wt<wt_1){
        drawTextRelative(-1, BelowBar1, "Sell", Color.red, null, Text.PRESET|Text.CENTER, "Arial", 11,"Sell"+rawtime());
    }else{
        removeText("Sell"+rawtime());
    } 

which will draw the Buy and Sell text using the same conditions.
