Hi,

You have to use outputs instead of IndicatorDataSeries fields, then you will be able to use your indicator on a cBot by referencing.

Also you can put the whole indicator code on a cBot, example:

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

namespace NewcBot2
{
    [Robot(AccessRights = AccessRights.None)]
    public class NewcBot2 : Robot
    {
        [Parameter("Show High,Low", DefaultValue = true)]
        public bool showHL { get; set; }

        private IndicatorDataSeries _haOpen;
        private IndicatorDataSeries _haClose;
        private IndicatorDataSeries _haHigh;
        private IndicatorDataSeries _haLow;

        protected override void OnStart()
        {
            _haOpen = CreateDataSeries();
            _haClose = CreateDataSeries();
            _haHigh = CreateDataSeries();
            _haLow = CreateDataSeries();
        }

        protected override void OnBar()
        {
            var index = Bars.Count - 2;

            var open = Bars.OpenPrices[index];
            var high = Bars.HighPrices[index];
            var low = Bars.LowPrices[index];
            var close = Bars.ClosePrices[index];

            var haClose = (open + high + low + close) / 4;

            if (double.IsNaN(_haOpen[index - 1]))
            {
                _haOpen[index - 1] = Bars.OpenPrices[index - 1];
            }

            var haOpen = (index > 0) ? (_haOpen[index - 1] + _haClose[index - 1]) / 2 : (open + close) / 2;
            var haHigh = Math.Max(Math.Max(high, haOpen), haClose);
            var haLow = Math.Min(Math.Min(low, haOpen), haClose);

            _haOpen[index] = haOpen;
            _haHigh[index] = haHigh;
            _haLow[index] = haLow;
            _haClose[index] = haClose;

            if (index < 4) return;

            var position = Positions.Find("MyBot");

            if (_haClose[index] > _haOpen[index] && _haClose[index - 1] < _haOpen[index - 1])
            {
                if (position != null && position.TradeType == TradeType.Sell) ClosePosition(position);

                ExecuteMarketOrder(TradeType.Buy, SymbolName, Symbol.VolumeInUnitsMin, "MyBot");
            }
            else if (_haClose[index] < _haOpen[index] && _haClose[index - 1] > _haOpen[index - 1])
            {
                if (position != null && position.TradeType == TradeType.Buy) ClosePosition(position);

                ExecuteMarketOrder(TradeType.Sell, SymbolName, Symbol.VolumeInUnitsMin, "MyBot");
            }
        }
    }
}

The above cBot opens a buy position on start of green line and a sell position on start of red line, it closes the buy position on start of red line and the sell position on start of green line.

            var close = Bars.ClosePrices[index];

            var haClose = (open + high + low + close) / 4;

            if (double.IsNaN(_haOpen[index - 1]))
            {
                _haOpen[index - 1] = Bars.OpenPrices[index - 1];
            }

            var haOpen = (index > 0) ? (_haOpen[index - 1] + _haClose[index - 1]) / 2 : (open + close) / 2;
            var haHigh = Math.Max(Math.Max(high, haOpen), haClose);
            var haLow = Math.Min(Math.Min(low, haOpen), haClose);

            _haOpen[index] = haOpen;
            _haHigh[index] = haHigh;
            _haLow[index] = haLow;
            _haClose[index] = haClose;

            if (index < 4) return;

            var position = Positions.Find("MyBot");

            if (_haClose[index] > _haOpen[index] && _haClose[index - 1] < _haOpen[index - 1])
            {
                if (position != null && position.TradeType == TradeType.Sell) ClosePosition(position);

                ExecuteMarketOrder(TradeType.Buy, SymbolName, Symbol.VolumeInUnitsMin, "MyBot");
            }
            else if (_haClose[index] < _haOpen[index] && _haClose[index - 1] > _haOpen[index - 1])
            {
                if (position != null && position.TradeType == TradeType.Buy) ClosePosition(position);

                ExecuteMarketOrder(TradeType.Sell, SymbolName, Symbol.VolumeInUnitsMin, "MyBot");
            }
        }
    }
}

The above cBot opens a buy position on start of green line and a sell position on start of red line, it closes the buy position on start of red line and the sell position on start of green line.

Dear Mr. Ahmed,

Thanks for posting the above Sample cBot that can be used by Referencing an Indicator, and it opens a buy position on start of green line and a sell position on start of red line, it closes the buy position on start of red line and the sell position on start of green line.

Kindly also advice how to Add Parameters such as Volume/Lot Size,  ATR Period, and  ATR Multiplier to this cBot, if we are Referencing it with SuperTrend Indicator.

Thanks & Best Regards,

Altaf
