Hi Alexander,

Try something like this

            var source = MarketData.GetSeries(TimeFrame.Minute15).High;
            var _bb = Indicators.BollingerBands(source, 20, 2, MovingAverageType.Exponential);

Hi DelTrader, 

Thanks but probably this is not enough, As I said, it seems that your condition is never fulfilled. In order to understand why the condition is not fullfiled, we will need to know what values do the different variables have at the time when this line of code is reached. So the only way to do this is to actually debug the cBot. This means that we will need the full source code as well as the execution parameters (Symbol, timeframe etc). If you don't want to expose your cBot publicly, you can contact me at community@spotware.com.

Best Regards,

Panagiotis

Hi thoy1,

Just to make sure what you are asking for, you need this part 

        protected override void OnPositionClosed(Position last)
        {
            foreach (var position in Positions)
            {
                if (position.NetProfit > -1)
                {
                    ClosePosition(position);
                }
            }

not to trigger OnPositionsClosed again, right?

Best Regards,

Panagiotis

Hi thegreat.super,

Here s a guide that explains how to debug cBots in Visual Studio. Paul Hayes has also created a couple of cool videos on this subject. You can find one here

Hi dordkash@gmail.com,

You can use a boolean flag that will be reset on each OnBar()

Hi Medjan,

This is not in our current plans however I would recommend you to post it in our Suggestions section to be consdered for future releases.

Hi dordkash@gmail.com,

Consider putting your logic in the OnTick()  function instead of in the OnBar().

Hi megamemo,

Thanks for the nice feedback and the clarifications as well. Maybe you would llke to contact a professional Consultant to help you with such a cBot or post a job in the Jobs section.

Hi megamemo,

It is not very clear to us what you are looking for. Do you need a cBot that implements OCO? Please elaborate so that we can help you.

Hi DelTrader,

Most probably your condition is not fulfilled

 if (myPositionsSymbol1.Length <= (MaxOpenTradesSymbol1 - 1) && Symbol1Spread <= MaxSpreadSymbol1)
                {

However we cannot advise further if we don't know what this condition is supposed to do and what do the parameters mean. For example, we don't know what MaxOpenTradesSymbol1 or  LabelSymbol1 

Best Regards,

Hi JoaoRMartins,

This is a known issue and it is going to be resolved in the next release of the API.

Hi dordkash@gmail.com,

You have the following condition in OnBar()?

if (Symbol.Bid - MarketSeries.High.Last(1) > Symbol.PipSize)
    ExecuteMarketOrder(TradeType.Buy, Symbol, VOL, label, buypips, tp);

This code is executed as soon as a bar closes and a new one is created. This means that the first tick of the new bar should be 1 pip higher that the highest price of the last bar. Ever if the last tick of the previous bar was the highest price recorded for that bar, it is very unlikely that the first tick of the new bar will be 1 pip higher.

Best Regards,

Panagiotis

Hi dordkash@gmail.com,

Your code is located in the OnBar method. It is highly unlikely that the bid price will become higher by one pip from the previous high. Maybe you would like to reconsided your logic.

Best Regards,

Hi thegreat.super,

Unfortunately, it is not easy to help you if I don't have the same conditions as you. I have provided a link above that explains what this exception means. Probably a variable is used somewhere without being initialized first or having a null value. If you try to debug this cBot using Visual Studio, then it will be easy to find out where the exception is thrown and fix it. 

Best Regards,

Hi swingfish,

If you want to remove TP and SL from a position, you need to modify it and set the relevant fields to null. See below

 ModifyPosition(position, null, null);

A suggestion to improve your cBot's performance is to keep track of the open volume during position opening and closing so that you can avoid the loop that counts it.

Let me know if this helps you

Hi Elias,

You can develop your cBot based on the example above. If you need professional help developing your cBot you can contact a Consultant or post a Job.

Hi luoyefengxing,

Please send us the cBot code and the backtesting configuration so that we can check and tell you why it stopped.

Hi Elias,

It is not very clear what you are trying to do since the code you have posted seems to be a mixup of a cBot and an Indicator. If you want to call the MACD Crossover indicator in a cBot, see a simple example below.

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

namespace cAlgo
{
    [Robot(TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class NewcBot : Robot
    {
        [Parameter(DefaultValue = 0.0)]
        public double Parameter { get; set; }
        private MacdCrossOver _macdCrossOver;
        
        protected override void OnStart()
        {
            _macdCrossOver = Indicators.MacdCrossOver(28,12,9);
        }

        protected override void OnTick()
        {
            
        }

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

Let me know if this is what you are looking for.

Hi luoyefengxing,

Thanks for posting in our forum. Why do you say that cBot uses data only in 2014? What makes you think that?

Best Regards,

Hi Alexander,

The cBot stops because of this condition

            if (StoppedByRobot == false)
            {
                Print("Sorry");
                Stop();
            }

What was your intention writing this part?

Best Regards,

Panagiotis
