RE: Market Sentiment via API?

Will the market Sentiment become accessible in bots, perhaps via the API?

We do not have such plans at the moment.

Hi NE539,

I do not have an exhaustive list of all the differences but the major one is that you cannot use custom indicators and cBots on cTrader Web. Furthermore, from time to time some features might be available on one platform because they have not been delivered on the other, but in general we are trying to keep both applications on par. In terms of performance, you should expect a better performance from the desktop application since it is native compared to cTrader Web that needs to run within a browser.

Hi team500,

This indicator can switch a chart's timeframe and symbol but not open a new chart or close the existing one. The functions it uses are the following

Hi there, 

To fix this issue you need to add a dummy to the indicator and call it from the cBot. See below

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

namespace cAlgo
{
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class Chickens : Indicator
    {
        [Parameter("Source")]
        public DataSeries Source { get; set; }

        [Output("Main")]
        public IndicatorDataSeries Result { get; set; }

        public int counter = 1;


        protected override void Initialize()
        {
            // Initialize and create nested indicators
            Print("INDICATOR PRINT | calculate | initial value for \"counter\"  " + counter);
        }

        public override void Calculate(int index)
        {

            counter = counter > 100 ? 0 : ++counter;
            ChartObjects.DrawText("max100", "counter " + counter, StaticPosition.BottomRight, Colors.Plum);
        }
    }
}

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 ChickenCounter : Robot
    {
        [Parameter(" Source")]
        public DataSeries Source { get; set; }
        private Chickens chick;

        protected override void OnStart()
        {
            // Put your initialization logic here
            chick = Indicators.GetIndicator<Chickens>(Source);
        }

        protected override void OnTick()
        {
            // Put your core logic here
            Print(chick.Result.LastValue);
            Print("OnTick | counter  " + chick.counter);
        }

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

Hi silvanaskocic75,

Did you do anything else than just installing cTrader on desktop e.g. placed orders or opened any positions?

Hi TzvetomirTerziysky,

As explained above the exception was added in 3.7. After receiving a lot of complaints from users, we have reverted to how it was working in v3.6. It was never working in optimization.

Hi TzvetomirTerziysky,

We put nothing under the carpet. This was never working in optimization. It was just not throwing an exception in v3.6. We restored this functionality in v3.7.

Hi Pep,

1) The reason behind the NaN values is that you are trying to access indices with negative values (index - ik). You should make the relevant checks and make sure you are using an index with a positive value.

2) The gap issue is not related with the NaN issue. To fix the gap issue just start adding values from the index before i.e. the start index and value of the green series should be the same with the end index and value of the red series and vise versa.

Hi reza h,

Your question is very general for somebody to give you a specific answer. So I will try to give a general answer to a general question, in case it helps. Use a flag that will be raised when the first hammer is detected. When the flag has been raised, do not detect any hammers. Lower the flag whenever you think it should be lowered.

Hi henderson.nigel,

No there is no such setting. Please make sure you are using the same setting i.e. optimization method and cBot parameters.
