Hi ceakuk,

See below the first example as a robot

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

namespace cAlgo.Robots
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter(DefaultValue = 30, MinValue = 1)]
        public int Period { get; set; }

        protected override void OnStart()
        {
            // Put your initialization logic here
        }

        protected override void OnTick()
        {
            RedrawLines();
        }
        private void RedrawLines()
        {
            int count = MarketSeries.Close.Count;

            int maxIndex1 = FindNextLocalExtremum(MarketSeries.High, count - 1, true);
            int maxIndex2 = FindNextLocalExtremum(MarketSeries.High, maxIndex1 - Period, true);

            int minIndex1 = FindNextLocalExtremum(MarketSeries.Low, count - 1, false);
            int minIndex2 = FindNextLocalExtremum(MarketSeries.Low, minIndex1 - Period, false);

            int startIndex = Math.Min(maxIndex2, minIndex2) - 100;
            int endIndex = count + 100;

            DrawTrendLine("high", startIndex, endIndex, maxIndex1, MarketSeries.High[maxIndex1], maxIndex2, MarketSeries.High[maxIndex2]);

            DrawTrendLine("low", startIndex, endIndex, minIndex1, MarketSeries.Low[minIndex1], minIndex2, MarketSeries.Low[minIndex2]);
        }

        private void DrawTrendLine(string lineName, int startIndex, int endIndex, int index1, double value1, int index2, double value2)
        {
            double gradient = (value2 - value1) / (index2 - index1);

            double startValue = value1 + (startIndex - index1) * gradient;
            double endValue = value1 + (endIndex - index1) * gradient;

            ChartObjects.DrawLine(lineName, startIndex, startValue, endIndex, endValue, Colors.Gray);
            ChartObjects.DrawLine(lineName + "_red", index1, value1, index2, value2, Colors.Red);
        }

        private int FindNextLocalExtremum(DataSeries series, int maxIndex, bool findMax)
        {
            for (int index = maxIndex; index >= 0; index--)
            {
                if (IsLocalExtremum(series, index, findMax))
                {
                    return index;
                }
            }
            return 0;
        }

        private bool IsLocalExtremum(DataSeries series, int index, bool findMax)
        {
            int end = Math.Min(index + Period, series.Count - 1);
            int start = Math.Max(index - Period, 0);

            double value = series[index];

            for (int i = start; i < end; i++)
            {
                if (findMax && value < series[i])
                    return false;

                if (!findMax && value > series[i])
                    return false;
            }
            return true;
        }

        protected override void OnStop()
        {
            // Put your deinitialization logic here
        }
    }
}

Let me know if this helps.

Hi MaRCHeW,

When you get 0% for v2.01, is the application minimized or maximized? If it is minimized could you please maximize and make the comparison again?

Hi rmsuleman,

I tried to build the indicator and I have no problems. However the error message references Robots folder which is used for cBots. Am I missing something?

Hi FMogyi,

You don't need any special cAlgo libraries. cAlgo can reference any .Net library since it is a .Net application. Here you can find how to create a .Net library.

Hi Adam,

Your broker was correct. Percentages and ratios are related to the volume traded by the strategy provider. Proportional mirroring with be a feature that will be introduced in the upcoming release of cTrader Copy which is planned to be released sometime in Q2 2018.

Hi all,

Thanks for reporting this, Could you please provide us with the below information?

• What is the revision of Spotware cTrader 3.0 you are using? (press Ctrl+Shift+~R)
• Do you use any cBots or indicators in the moment of high CPU consumption?
• What charts are using? Are you using any Chart objects like Deal Maps?

If you could share a couple of screenshots of Spotware cTrader, it would be useful as well.

Best Regards,

Hi tradermatrix

The exception is thrown in the following function

        private TradeType GetTradeCommand()
        {
 
            if (_movingAverage.Result.IsRising())
                return TradeType.Buy;
            if (_movingAverage.Result.IsFalling())
                return TradeType.Sell;
            return _position.TradeType;
        }

_position is not set anywhere, therefore always null
