Chart.MouseMove cannot read Object Properties

Hi bienve.pf,

I checked this with the product team and the this behavior is normal of interactive objects. A workaround is to create a non-interactive line for drawing purposed and make it interactive on second mouse click. Like this

Chart.MouseDown += arg =>
            {
                Print("MouseDown event....");
                if (_line == null)
                {
                    _line = Chart.DrawTrendLine("myline", arg.TimeValue, arg.YValue, arg.TimeValue, arg.YValue, Color.Yellow, 2);
                    _line.IsInteractive = false;
                }
                else
                {
                    _line.IsInteractive = true;
                    _line = null;
                }
            };

Let me know if this helps.

Hi,
the problem is that if I move the line through one of its vertices it is not possible to capture or read the properties (Time / Y) while moving to be able to dynamically move a text with or other linked lines with it

look at the yellow text on left of Chart while moving the line. Data is not updated until object is dropped

Hi bienve.pf,

Here is the complete cBot code. It seems to work fine for me

using System;
using System.Linq;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter("Timeframe")]
        public TimeFrame Timeframe { get; set; }

        protected override void OnStart()
        {
            ChartTrendLine _line = null;

            Chart.MouseMove += arg =>
            {
                if (_line != null)
                {
                    _line = Chart.DrawTrendLine("myline", _line.Time1, _line.Y1, arg.TimeValue, arg.YValue, Color.Yellow, 2);
                    Chart.DrawStaticText("info", "Time1: " + _line.Time2.ToString() + "/ Y1: " + _line.Y2, VerticalAlignment.Top, HorizontalAlignment.Left, Color.Yellow);
                }
            };
            Chart.MouseDown += arg =>
            {
                Print("MouseDown event....");
                if (_line == null)
                {
                    _line = Chart.DrawTrendLine("myline", arg.TimeValue, arg.YValue, arg.TimeValue, arg.YValue, Color.Yellow, 2);
                    _line.IsInteractive = false;
                }
                else
                {
                    _line.IsInteractive = true;
                    _line = null;
                }
            };

        }

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}
