Dear Ciro,

The KST indicator is a weighted summed rate of change oscillator that is designed to identify meaningful turns. Various smoothed rate of change indicators can be combined to form different measurements of cycles. For more interpretation refer to Martin Pring's article "Summed Rate of Change (KST)" in the September 92 issue of TASC.

Usage:

- One method of using the KST is to apply trendline analysis to the indicator.

- The KST can also be interpreted with the same principles that would be applied to other oscillators.

Code:

Code:

var roc6 = new ROCStudy(6, "Close");
var roc10 = new ROCStudy(10, "Close");
var roc15 = new ROCStudy(15, "Close");
var roc20 = new ROCStudy(20, "Close");

function preMain()
{
    setStudyTitle("KST");
    setCursorLabelName("KST", 0);
    setDefaultBarFgColor(Color.blue, 0);
    addBand(0, PS_SOLID, 1, Color.black);
}

function main() {

    var i;
    var vROC6 = roc6.getValue(ROCStudy.ROC,0,-10);
    var vROC10 = roc10.getValue(ROCStudy.ROC,0,-10);
    var vROC15 = roc15.getValue(ROCStudy.ROC,0,-8);
    var vROC20 = roc20.getValue(ROCStudy.ROC,0,-15);
    var Sum6 = 0, Sum10 = 0, Sum15 = 0, Sum20 = 0;
    
    
    if(vROC6 == null || vROC10 == null || vROC15 == null || vROC20 == null)    
    	return;
    for(i = - 14; i <= 0; i++){
	if(i > -6)
    		Sum6 += roc6.getValue(ROCStudy.ROC,i);
    	if(i > -10)
    		Sum10 += roc10.getValue(ROCStudy.ROC,i);
	if(i > -8)
    		Sum15 += roc15.getValue(ROCStudy.ROC,i);;
	Sum20 += roc20.getValue(ROCStudy.ROC,i);;
    }

   return (Sum6 / 6 + (Sum10 / 10) * 2 + (Sum15 / 8) * 3 + (Sum20 / 15) * 4);
}

If you have any further questions or require additional assistance please let me know.

Regards,
Andy

Thanks a lot

Dear andy,
i have receipt your answer and efs code, thank a lot!!!
I want to add at kst a moving average as trigger, how is possible to make it ?

Trading sistem

Dear Andy,
i want to built my personal TS, but i don't understand how to built it. As set stop, trailing stop and etc....

Do you can help me ?? in my first time ??

the idea is simple....
i want to buy (do.long) when ema14>kst or short when ema14<kst...

two exit condition
1) Low(-4) >= low(-2)&&
low(-3) >= low(-2)&&
low(-1) >= low(-2)&&
low() >= low (-2)
if is true then low(-2) is my trailing stop (new stop)

else exit when (long) ema14<kst or (short) or ema14>kst

Can you help me ??
thank ciro
