I just start C#

but the code have error

pls help me , thank you

Hi Psak,

Thanks for posting in our forum. What is DX? A custom indicator? Can you please provide it as well?

Yes DX is custom indicator

the indicator is ok

but i need build it for multi TF

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

namespace cAlgo.Indicators
{
    [Indicator("DMS", IsOverlay = false, ScalePrecision = 0, TimeZone = TimeZones.UTC, AccessRights = AccessRights.None)]
    public class DX : Indicator
    {
        [Parameter("Period", DefaultValue = 14, MinValue = 1)]
        public int Period { get; set; }

        [Parameter("MA Type", DefaultValue = MovingAverageType.Exponential)]
        public MovingAverageType MaType { get; set; }

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

        [Output("EADS", Color = Colors.Cyan)]
        public IndicatorDataSeries EMAA { get; set; }

Hi Psak,

You did not provide the complete indicator code. Also, this part of the code does not make sense.

            ma = dxx.A(MarketSeries.Close, 27, MovingAverageType.Exponential);
            ma5 = dxx.A(series5.Close, 27, MovingAverageType.Exponential);
            ma10 = dxx.A(series10.Close, 27, MovingAverageType.Exponential);

Would you like to explain to what are you trying to do here?

Best Regards,

Panagiotis

sorry panagiotis

I think my custom indicators have many bugs

this is complete code

Hi Psak,

Thanks but you did not answer my question. What are you trying to do in the lines Ι quoted above? Are you trying to initialize the indicator? If yes, then this is wrong. You need to use Indicators.GetIndicator<>() function. You can read more about it here, in the Referencing Custom Indicators section.

Best Regards,

Panagiotis

thank you

yes I need try Initialize same as example

Multiple timeframes , Example 1- Using multiple timeframes https://ctrader.com/api/guides/indicators#el12

I try getindicator but it don't work with

dxx = Indicators.GetIndicator<DX>(27, MovingAverageType.Exponential);

Hi Psak,

The problem is these lines

            ma = dxx.A(MarketSeries.Close, 27, MovingAverageType.Exponential);
            ma5 = dxx.A(series5.Close, 27, MovingAverageType.Exponential);
            ma10 = dxx.A(series10.Close, 27, MovingAverageType.Exponential);

They don't make any sense and I cannot help you if you do not explain to me what are you trying to do here. If you delete them, your indicator will build without problems.

Panagiotis
