AI Generate custom indicator?

[ErikHR1969]

Hi,

Can I use a custom indicator with the AI Generate optimization?
If so, any direction would be appreciated.

Thanks,
Erik

Yes, if the custom indicator only uses one data series.

See the following walk-through, and expand the section How to Run an AI Generate Optimization:

Hello Erik,

The AI Generator is not designed to produce indicators. This instead is using a set of pre listed indicators to find combinations of conditions that place orders and lead to a performance result.

It's not designed to set plot values or draw objects, or do things that indicators do.

That said, you can copy the logic from a strategy to a new indicator script and remove any order related code.

Below is a link to a video about copying code from one script to another.

Hi all thanks for the responses.

I have an indicator called "MyInd".
I added it her:

    public class StrategyGenerator : Optimizer
    {
        private int                        oldKeepBestResults            = -1;
        private    ChartPattern[]            selectedCandleStickPattern;
        private Type[]                    selectedIndicatorTypes;

        public    static ChartPattern[]    AvailableCandleStickPattern    = Enum.GetValues(typeof(ChartPattern)).Cast<ChartPattern>().ToArray();

        // Subjective selection of indicators which 'make most sense'. The full set of indicators would be used if this selection would not be set
        // The optional tuple defines the range of random comparison values for oscillators (where such range could be defined)
        // Feel free to modify to your liking...
        internal    static Dictionary<Type, Tuple<double, double>> AvailableIndicators = new Dictionary<Type, Tuple<double, double>>()
                                                        {
                                                            { typeof(Indicators.MyInd),                       null },
                                                            { typeof(Indicators.ADL),                       null },​

It shows up when I run AI Generate as an indicator I can select for my AI Optimization.
When I try to run the AI Generate with "MyInd" selected as one of the indicators to use the application hangs.

Can anyone give me any ideas on what I may be doing wrong and\or if this is possible to do?

Thanks,
Erik

Hello Erik,

This appears to be code for a custom optimizer script and not an indicator.

This would imply you are not using the AI Generate or you have posted the code from the wrong script.

That said, I would recommend you comment out all of the logic and variables and ensure the issues does not occur, then uncomment (blocks) of variables first, then logic one line at a time, until the behavior returns. There may be issues (such as improper auto setters that get stuck in a loop) causing the behavior.
Commenting out code will help you zero in on the specific line causing the error.
