Hello,

Is it the indicator found here /algos/show/207 that you are refering to?

Hello, 

I use another Indicators, but I have the same problem. I have to reload all indicators when I restart cAlgo, because the displayed values NaN. The reloading solved the problem, but please investigate it because it's very uncomfortable.

Thanks in advance!

RE:

Yes I'm using that tick indicator, also I have a indicator that shows the pips between SMA and that is not working as well.  Instead of the data I get "NaN" same on tick indicator.

Thank you. You need to send us an email to engage@ctrader.com and let us know which cAlgo you are using (from Top Menu -> Help -> About cAlgo)

We have identified an issue with cTrader and are currently working on a solution which should be available in the next release. cAlgo is working properly though.

Hello,

Sorry, but cAlgo has the same problem!

As I mentioned above the displayed values of indicator are "NaN" on charts. Please investigate it.

Thanks

Hi Scott,

We apologize for the inconvenience that this is causing. Please try to use cAlgo for the time being. The next release is soon. We will look at your code even though I suspect it the same issue.

Regards,

cAlgo_Fanatic

We have identified the problem and are currently working on the solution. Again, we apologize for this inconvenience.

The problem has been identified to be affecting only indicators displayed on a separate panel.  A temporary workaround would be to modify the indicator to be overlayed on the chart.

  [Indicator(IsOverlay = true)]

For the tick chart indicator the workaround solution would be to access Symbol properties such as Ask and Bid via the Depth of Market. Other Symbol properties such as the Symbol code, pipsize may be input parameters or hardcoded.

TickChart Modified code:

using System;
using cAlgo.API;

namespace cAlgo.Indicators
{
    [Indicator(ScalePrecision = 5, IsOverlay = false)]
    public class TickChart : Indicator
    {
        [Parameter("Symbol Code", DefaultValue = "EURUSD")]
        public string SymbolCode { get; set; }

        [Parameter("PipSize", DefaultValue = 0.00001)]
        public double PipSize { get; set; }

        [Output("Ask", Color = Colors.Blue)]
        public IndicatorDataSeries Ask { get; set; }

        [Output("Bid", Color = Colors.Red)]
        public IndicatorDataSeries Bid { get; set; }

        private MarketDepth depth;
        private double ask;
        private double bid;

        protected override void Initialize()
        {
            depth = MarketData.GetMarketDepth(SymbolCode); // We must explicitly specify symbol code here
            depth.Updated += OnDepthUpdated;
        }

        private void OnDepthUpdated()
        {
            if (depth.AskEntries.Count > 0 && depth.BidEntries.Count > 0)
            {
                ask = depth.AskEntries[0].Price;
                bid = depth.BidEntries[0].Price;

                ChartObjects.DrawText("QuotesLabel", "BID: " + bid + ", ASK: " + ask, StaticPosition.TopCenter);
            }
        }
        private static void ShiftDataSeries(IndicatorDataSeries dataSeries)
        {
            for (var i = 0; i < dataSeries.Count - 1; i++)
            {
                dataSeries[i] = dataSeries[i + 1];
            }
        }

        private static void FillDataSeries(IndicatorDataSeries dataSeries, double value, int startIndex, int count)
        {
            for (var i = startIndex; i < startIndex + count; i++)
                dataSeries[i] = value;
        }

        public override void Calculate(int index)
        {
            if (!IsRealTime)
                return;

            if (!double.IsNaN(Ask[index]))
            {
                ShiftDataSeries(Ask);
                ShiftDataSeries(Bid);
            }

            FillDataSeries(Ask, ask, index, 50);
            FillDataSeries(Bid, bid, index, 50);

            var spread = Math.Round((ask - bid) / PipSize, 1);
            ChartObjects.DrawText("Spread label", "Spread:\t" + spread + " pips", StaticPosition.BottomRight);
        }

        
    }
}

The next release will be between 27/2 and 05/03.

This happens everytime theres an update. Nothing seems to work again and again and yet again. Its getting some what anoying. Also why is my profit on the new market order on the euro/usd now calculated in euros yet on a limit order its calculated in gbp. i have to say that over the course of the last year that ive been using this kit i very much doubt you guys test anything before you release the update. Is it beyond your scope of development to bother to test your work. Also how long does it take to develop a trailing stop thats built into the program as standard. A basic feature in most trading programs. Yet still not in c trader.

Can you please send us a screenshot of this. Why do you think it is calculated in GBP?

22 Feb 2013, 11:57

im not usualy this grumpy in the morning and i really do like the kit but these little things start to add up to a lot over the course of time. click the scroll> market order next to the word profit (eur) yet you then click on limit order then next to the word profit (gbp) then check stop order this also says profit(GBP) so what is it GBP or EUR?

cAlgo_Fanatic
22 Feb 2013, 12:46

RE:

The issue lies with updating the text string from EUR to the account's currency. The correct is the account's currency, in your case I presume GBP. It will be fixed in the next release. Again, we apologize for the error and thank you for your patience while we resolve this.

RE:

Hi Support 

Got it working by having it as a overlay on the chart, however there seams to be a problem with USDJPY its not showing the last 3 calculations see below

Thanks

If you changed the code please repost it so that we can investigate. The original code you posted with the only modification of overlaying the output on the chart produces this result:
