Turning the indicator inside the program on and off.
26 Feb 2019, 09:05

Hello.
Hello.
Is it possible to turning the indicator inside the program on and off.?
In the following example, the average does not appear at all. There is no problem with the "Clock" object.

using System;
using System.Linq;
using System.Text;
using System.IO;
using System.Collections.Generic;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;
using cAlgo.Indicators;


namespace cAlgo
{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class TEST2 : Indicator
    {

        private bool showSMA;
        private int i;

        public int redPeriod = 12;
        [Output("Red SMA", LineColor = "Red", Thickness = 1)]
        public IndicatorDataSeries redSMA { get; set; }


        private MovingAverage _redSMA;


        protected override void Initialize()
        {
            Timer.TimerTick += OnTimerTick;
            Timer.Start(1);

            _redSMA = Indicators.MovingAverage(MarketSeries.Close, redPeriod, MovingAverageType.Simple);            
        }

        public override void Calculate(int index)
        {
            if (showSMA)
            {
                redSMA[index] = _redSMA.Result[index];

            }
        }

        private void OnTimerTick()
        {
            i++;

            if (i > 5 && i < 20)
            {
                showSMA = true;
                ChartObjects.DrawText("Clock", Time.ToString("HH:mm:ss"), StaticPosition.TopLeft);
            }
            else
            {
                showSMA = false;
                Chart.RemoveObject("Clock");
            }
        }
    }
}

Hi lw3010996,

The reason you see nothing is because showSMA is always false.

After 5 seconds I want to display Clock and SMA for 15 seconds. The clock displays correctly the SMA does not. The "showSMA" condition is true for 15 seconds.

using System.Linq;
using System.Text;
using System.IO;
using System.Collections.Generic;
using cAlgo.API;
using cAlgo.API.Indicators;
using cAlgo.API.Internals;

{
    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class TEST2 : Indicator
    {

        private bool showSMA;
        private int i;

        public int redPeriod = 12;
        [Output("Red SMA", LineColor = "Red", Thickness = 1)]
        public IndicatorDataSeries redSMA { get; set; }


        private MovingAverage _redSMA;


        protected override void Initialize()
        {
            Timer.TimerTick += OnTimerTick;
            Timer.Start(1);

            _redSMA = Indicators.MovingAverage(MarketSeries.Close, redPeriod, MovingAverageType.Simple);
        }

        public override void Calculate(int index)
        {
            if (showSMA)
            {
                ChartObjects.DrawText("Clock", Time.ToString("HH:mm:ss"), StaticPosition.TopLeft);
                redSMA[index] = _redSMA.Result[index];

            }
            else
            {
                Chart.RemoveObject("Clock");
            }
        }

        private void OnTimerTick()
        {
            i++;

            if (i > 5 && i < 20)
            {
                showSMA = true;
            }
            else
            {
                showSMA = false;
            }
        }
    }
}

It seems that the code works, however, not as I wanted. The SMA indicator is drawn in the chart only from the moment when the "showSMA" condition is true, not in the entire chart.

Is there any way to show and hide the working indicator with a code?

Thank you, exactly the effect I tried to achieve. Unfortunately, my way was wrong.

I have one more question. I'm trying to rewrite the code to show and hide on average from a different time frame. Unfortunately, the average I display shows bad values.

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


namespace cAlgo

    [Indicator(IsOverlay = true, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None, AutoRescale = false)]

        //private int i;

        public int redPeriod = 12;
        [Output("Red SMA", LineColor = "Red", Thickness = 1)]
        public IndicatorDataSeries RedSMA { get; set; }

        [Output("Red SMA M15", LineColor = "Red", Thickness = 3)]

            _redSMA = Indicators.MovingAverage(MarketSeries.Close, redPeriod, MovingAverageType.Simple);

            seriesM15 = MarketData.GetSeries(TimeFrame.Minute15);
            _redSMA15 = Indicators.MovingAverage(seriesM15.Close, redPeriod, MovingAverageType.Simple);

Hi lw3010996,

It seems you are using wrong indices in OnTimerTick() while you have implement the logic correclty in Calculate().
