Help needed to modify the indicator

Dear All,

I have modified one indicator to form a overlay basket of the price levels of EU,EJ & UJ. This indicator is calculating and showing the desired results while offline. When we go for live it is keep on updating and showing no price difference between these basket. I am attaching the indicator herewith can anyone modify the indicator basket so that it would not recalculate continuously.
