It is not possible to drag the lines produced by an indicator.  You can only drag lines added manually on the chart.

For drawing straight lines you should use ChartObjects.DrawLine.

How can I make my horizontal lines movable? ie...draggable

 

This is what I have right now...

//-------------------------------------------------------------------------------------------------------

using System;
using cAlgo.API;
using cAlgo.API.Indicators;

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC)]
    public class NewIndicator : Indicator
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        [Output("Main", PlotType = PlotType.Line)]
        public IndicatorDataSeries Result { get; set; }

       public override void Calculate(int index)
        {
            Result[index] = 1.3;
        }
    }
}

//-------------------------------------------------------------------------------------------------------

My question is this.How can I eliminate having to put in the value of the line (ie...1.3, etc...),

and make it draggable?

 

Thank you

 

 

 

Thank you for the kind words!
About the indicator it may be possible to create a custom indicator using the DrawLines method.
About adding volume to an existing position, it has been implemented and you will see it soon in one of the next releases.
