Hi itmfar,

I created an example based on your code and it seems to be working as expected. See code sample and screenshot below

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

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewIndicator : Indicator
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }
        private int secondGap;
        private int firstGap;

        protected override void Initialize()
        {
            secondGap = MarketSeries.Close.Count - 10;
            firstGap = MarketSeries.Close.Count - 20;
        }

        public override void Calculate(int index)
        {
            if (index > firstGap && index < secondGap)
                ChartObjects.DrawVerticalLine("v" + index, index, Colors.White);
        }
    }
}

Let me know if I misunderstood something.

Best Regards,

Panagiotis

thanks. it is ok. but it wont update if new bar comes up ,these 9 lines remain in their pervious positions but i need them to be drawn from 20 - 10 last bars at the moment.

the main purpose is that we able to make run our indicator for a period of time only. what would be the solution?

Hi itmfar,

Thanks now it is more clear what you are trying to achieve. You can try the following approach

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

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewIndicator : Indicator
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        protected override void Initialize()
        {
          
        }

        public override void Calculate(int index)
        {
            if (IsLastBar)
            {
                ChartObjects.RemoveAllObjects();
                for (int i = MarketSeries.Close.Count - 20; i < MarketSeries.Close.Count - 10; i++)
                    ChartObjects.DrawVerticalLine("v" + i, i, Colors.White);
            }
        }
    }
}

Let me know if this works for you.

                    ChartObjects.DrawVerticalLine("v" + i, i, Colors.White);
            }
        }
    }
}

thanks it works perfectly . is there any sensible solution for limiting time? such as modifying special date to start (start only after September 2017 to December 2017) ,instead of my method?

Hi itmfar,

With some more coding, you can develop something more proper, that could also take dates as input. But it will need somebody to devote time for this to developed. If i find some free time soon, then I might prepare something for you.
