Panagiotis,GOOD MOONING

​IN this pictrue, i watch in vs debugger, the indicator value of  Results[1506] is NAN,the value of  BarInfos[1056].trend is null,and this bar is the time of 2018-4-16 12:10. this is the Screenshots​ while the index is 1600,so i am sure than  the value of 1056th will be not calculated  in after time.

 public class BarInfo
    {
        public double High;
        public double Low;
        public int Index;
        public BarTrend Trend;
    }

List<BarInfo> BarInfos;

in below pictrue,in the chart,  Results[1506] is NAN value,is right, but the  value of   BarInfos[1056]     is UP not null value of watch list   in the time of 2018-4-16 12:10.

​the c# code  is blowe:

 string s = "";

            s = C.BarInfos[index].Trend.ToString();


            ChartObjects.DrawText(index.ToString(), s, index, Result[index] + 0.005, VerticalAlignment.Center, HorizontalAlignment.Center, Colors.White);

RE:

Hi yearn2012,

You can use a condition in the Calculate function and skip the calculation for bars before a certain time. See below

        private DateTime _openTime;
        protected override void Initialize()
        {
            // Initialize and create nested indicators
        }

        public override void Calculate(int index)
        {
            if (MarketSeries.OpenTime[index] > _openTime)
            {
                // Calculate Indicator;
            }
        }

Let me know if this helps,

 2.how to get the infos of current chart and all opened cha

What info of the chart do you need? Bars, spot prices, time?

RE:

Panagiotis Charalampous said:

Hi yearn2012,

The reason you cannot debug a custom indicator is because you probably installed cTrader 3.0 on a computer that already has cAlgo 2.01 installed. In this case, your existing cBots are not replaced, however they need a necessary addition in order to be debuggable in Visual Studio. In order to resolve this problem, please follow the next steps

1. Go to Properties > AssemblyInfo.cs
2. Add the following code at the bottom of the file

#if DEBUG
[assembly: Debuggable(DebuggableAttribute.DebuggingModes.Default | DebuggableAttribute.DebuggingModes.DisableOptimizations)]
#endif

This should fix your problem. Repeat this solution for every indicator/cBot you need to debug in Visual Studio. Newly generated cBots/Indicators should contain this attribute by default.
