Found a bug using Indicators.. in Initialize method
25 Sep 2024, 15:04

Hi,

sometimes, randomly, the indicators used in another indicator and created in the overrided initialize method is not created ! In fact I use the indicator in Calculate method and this method is called when the method Indicators.. is called ! so the pointer is null.

So I have to use something like that in the calculate method and now it works.

if(_stoch ==null) _stoch = Indicators.StochasticOscillator(stochPeriodK, slowing, stochPeriodD, stoch_matype)

Is it a new change in ctrader ? I didn't have this error before.

Thanks

Luc

forgot to add an information, it's mainly on Tick view

Put the view on Tick1000, switch to another tab, come back, switch to Tick250, etc…

RE: Found a bug using Indicators.. in Initialize method

Hi,

this is the code and a print screen. I have to switch from tab to tab, change the timeframe, etc. This indicator is in all tabs. When the bug arrive in a cbot it's very annoying ;-)

 

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

namespace cAlgo
{

    [Cloud("MACD", "Signal", Opacity = 0.2, FirstColor = "FF7CFC00")]
    [Indicator(IsOverlay = false, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class LucHADeltaMacd0Lag : Indicator
    {


        [Output("MACD", LineColor = "DodgerBlue", LineStyle = LineStyle.Lines)]
        public IndicatorDataSeries MACD { get; set; }

        [Output("Signal", LineColor = "Red", LineStyle = LineStyle.Lines, Thickness = 1)]
        public IndicatorDataSeries Signal { get; set; }

        [Parameter(DefaultValue = 12, Group = "MacD 0 Lag")]
        public int periodFast { get; set; }

        [Parameter(DefaultValue = 26, Group = "MacD 0 Lag")]
        public int periodSlow { get; set; }

        [Parameter(DefaultValue = 9, Group = "MacD 0 Lag")]
        public int periodSignal { get; set; }
        
        
        private MovingAverage emaSlow;
        private MovingAverage emaSlow2;
        private MovingAverage emaFast;
        private MovingAverage emaFast2;
        private MovingAverage emaSignal;
        private MovingAverage emaSignal2;
        private IndicatorDataSeries closePrice;
        private IndicatorDataSeries macd;

        protected override void Initialize()
        {
                              
            closePrice = CreateDataSeries();
            macd = CreateDataSeries();
            emaSlow = Indicators.MovingAverage(closePrice, periodSlow, MovingAverageType.Exponential);
            emaSlow2 = Indicators.MovingAverage(emaSlow.Result, periodSlow, MovingAverageType.Exponential);
            emaFast = Indicators.MovingAverage(closePrice, periodFast, MovingAverageType.Exponential);
            emaFast2 = Indicators.MovingAverage(emaFast.Result, periodFast, MovingAverageType.Exponential);
            emaSignal = Indicators.MovingAverage(macd, periodSignal, MovingAverageType.Exponential);
            emaSignal2 = Indicators.MovingAverage(emaSignal.Result, periodSignal, MovingAverageType.Exponential);
        }

        public override void Calculate(int index)
        {
            
            /*if(emaSlow==null) emaSlow = Indicators.MovingAverage(closePrice, periodSlow, macd_ma_type);
            if(emaSlow2==null) emaSlow2 = Indicators.MovingAverage(emaSlow.Result, periodSlow, macd_ma_type);
            if(emaFast==null) emaFast = Indicators.MovingAverage(closePrice, periodFast, macd_ma_type);
            if(emaFast2==null) emaFast2 = Indicators.MovingAverage(emaFast.Result, periodFast, macd_ma_type);
            if(emaSignal==null) emaSignal = Indicators.MovingAverage(macd, periodSignal, macd_ma_type);
            if(emaSignal2==null) emaSignal2 = Indicators.MovingAverage(emaSignal.Result, periodSignal, macd_ma_type);*/
            
           
            // MacD Zero Lag
            closePrice[index] = Bars.ClosePrices[index];
            MACD[index] = (2 * emaFast.Result[index] - emaFast2.Result[index]) - (2 * emaSlow.Result[index] - emaSlow2.Result[index]);
            macd[index] = MACD[index];
            Signal[index] = (2 * emaSignal.Result[index] - emaSignal2.Result[index]);

        }
    }
}

Is it possible due to the cloud ? …

 

Thanks for your help

Hi there,

It works fine for me.

Can you try recreating the indicator?

Hi Panagiotis,

I can't reproduce the bug too. It was easy before the update yesterday. So it seems fixed.

Befeore the update I saw that it was more often with indices like NAS100.

Thanks for your help

My apologies, I seem to be unable to create a new topic. 

Quick question. Can you explain why there have been no new cBots or indicators on your Algorithms section since 8th September? Normally, both those areas are pretty busy, but just seems to have drawn to a halt abruptly without any company PR/explanation. I personlly think this is bad for platform morale (the lack of comms) and makes you guys seem a little disconnected.

Anyway, apologies if it's just my login for some reason that's only seeing back to 8th September and if so, can you fix it for me -thanks

Hi there,

Now all new algorithms need to be uploaded to our store

So Panagiotis, just to confirm. Is the Algorithms [Indicators/Bots/Plugins] section dead then?? 

I never saw any announcement mentioning this, nor was there anything on any of the Algo pages, so was a bit confused.

The problem is still there this morning. It's random.
