Hi SmartArtsStudio,

There is no such option in the API to achieve that. The only way to achieve it is to set your time2 variable in a distant future time and keep the distance far away as the chart moves to the right.

That will work.
What would be the simplest method to add the ChartArea.Width to Chart.LastVisibleBarIndex to come up with a DateTime or X value in the future?
Thanks

The chart width unit is not in number of bars, its the width of chart, try this:

using cAlgo.API;

namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class InfinitRectangle : Indicator
    {
        // Use this later if you want to extend the rectangle more as user zoom in/out or scroll
        private ChartRectangle _rectangle;

        protected override void Initialize()
        {
            var numberOfVisibleBars = Chart.LastVisibleBarIndex - Chart.FirstVisibleBarIndex;

            var lastVisibleBarIndex = Chart.FirstVisibleBarIndex + Chart.MaxVisibleBars;

            _rectangle = Chart.DrawRectangle("rect", Chart.FirstVisibleBarIndex, Bars.HighPrices.Maximum(numberOfVisibleBars),
                lastVisibleBarIndex, Bars.LowPrices.Minimum(numberOfVisibleBars), Color.Red);
        }

        public override void Calculate(int index)
        {
        }
    }
}
