RE: RE:

Same thing for me, I have 20 symbols to load, each for 4 timeframes, without async it's not usefull. My code test if the bars has been fetched (test the null of the value and if the count is >0 ) before using it. I use a dictionary in the async method to add the bars in.

The problem is during the loop with MarketData.GetBarsAsync, if I have 5 symbols * 4 timeframes there are fetched without error, if I add one more symbols I will receive an error Symbol has no quotes for one of the symbols in my list, not the same timeframe. Sometime it's a symbol completely (all timeframes) and sometime it's on or two of thos 4 timeframes !

I tried to sleep and RefreshData after the sleep but the error is still there. The ‘solution’ with the Print does nothing (perhaps it was to do a call in the main thread ans refresh something we don't know).

Hi there,

It works fine for me.

Can you try recreating the indicator?

Best regards,

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

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

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; }

        protected override void Initialize()
        {
                              
            closePrice = CreateDataSeries();
            macd = CreateDataSeries();
            emaSlow = Indicators.MovingAverage(closePrice, periodSlow, 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);

            // 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

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…

Hi there,

You can create an indicator that would output the relevant data through the output data series.

Best regards,

Panagiotis

right !! thanks !
