For the others complaining about the script, this is just a function, you need to add your own statement.

wisewisely, be so kind, please, explain how “to add your own statement”.
With an example, please.

You complaining guys are so dumb it’s unbelievable. Learn AFL before complaining!! Jesus Christ.

_SECTION_BEGIN("Mann-Kendall");
Length= Param( "Period", 21, 5, 200, 1 ); 
function Trend(Price,Length) {

    Result = 0;
 
     
 
    for (k=Length;k<BarCount;k++) {
 
        S = 0;
 
        for (i=k-Length+1;i<k;i++) {         
            for (j=k-Length;j<i-1;j++) {
                Signum = sign(Price[i]-Price[j]);
                S += Signum;
