[serhatopcu]

    tvWidget.onChartReady(() =>  {   
      let crosshairValue;

      const crosshairMovedHandler = (params) => {
       crosshairValue = params;
      };

      tvWidget.activeChart().crossHairMoved().subscribe(null, crosshairMovedHandler);

      tvWidget.subscribe('mouse_down', () => {
       const mouseUpHandler = () => {
        console.log(crosshairValue);
        tvWidget.unsubscribe('mouse_up', mouseUpHandler);
       };

       tvWidget.subscribe('mouse_up', mouseUpHandler);
      });
    }
