    Priyanka,
    I developed the below code to use in my idea but when I added your last updated code I got a bug, whenever I move the mouse on the chart the stripline moves, I don’t want that I want when I click on spcific stripline of the 3 and move it normally,

    Excellent,
    so now how can I retrieve the price when I drag the stripLines, for example I dragged the stripLines into $3600, so I want to retrieve this value, how could I retrieve this value inside a variable, thanks in advance
