Hi Vamsi,

It is not clear what you are asking for. What lines do you want to plot? Could you post an example? What did you modify, what does it do and what should it be doing instead? What should this snippet do?

RE:

Let me explain more

I want to plot Horizontal Lines for High and Low of last N Periods. I got the code snippet from below. 

I want to plot lines like this. Above screenshot is for Daily High and Low.

using System;
using cAlgo.API;

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true)]
    public class DailyHighLow : Indicator
    {
        public override void Calculate(int index)
        {
            DateTime today = MarketSeries.OpenTime[index].Date;
            DateTime tomorrow = today.AddDays(1);

            double high = MarketSeries.High.LastValue;
            double low = MarketSeries.Low.LastValue;

            for (int i = MarketSeries.Close.Count - 1; i > 0; i--)
            {
                if (MarketSeries.OpenTime[i].Date < today)
                    break;

                high = Math.Max(high, MarketSeries.High[i]);
                low = Math.Min(low, MarketSeries.Low[i]);
            }

            ChartObjects.DrawLine("high " + today, today, high, tomorrow, high, Colors.Pink);
            ChartObjects.DrawLine("low " + today, today, low, tomorrow, low, Colors.Pink);
        }
    }
}

This is the code for above screenshot. But I want to plot High and Low for last 10 periods.

Hi Vamsi,

See below an example

using System;
using cAlgo.API;

namespace cAlgo.Indicators
{
    [Indicator(IsOverlay = true)]
    public class DailyHighLow : Indicator
    {
        public override void Calculate(int index)
        {
            if (IsLastBar)
            {
                double high = MarketSeries.High.Maximum(10);
                double low = MarketSeries.Low.Minimum(10);

                ChartObjects.DrawLine("high ", Bars.OpenTimes[index - 10], high, Bars.OpenTimes[index], high, Colors.Pink);
                ChartObjects.DrawLine("low ", Bars.OpenTimes[index - 10], low, Bars.OpenTimes[index], low, Colors.Pink);
            }
        }
    }
}
