Hosted indicators identity

[fx.practic]

Here is example of code and result on screenshot in attachment:

        SMA Sma_1, Sma_2;
        
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Calculate                                    = Calculate.OnBarClose;
            }
            else if (State == State.DataLoaded)
            {
                Sma_1 = SMA( 10 );
                Sma_2 = SMA( 10 );
                
                AddChartIndicator( Sma_1 );
                
                Print( "Sma_1 == Sma_1 = "+ (Sma_1 == Sma_1).ToString() );                
            }
        }

        protected override void OnBarUpdate()
        {            
            Sma_2.PlotBrushes[0][0] = Brushes.Blue;
        } 

If to use different periods, for example

                Sma_1 = SMA( 10 );
                Sma_2 = SMA( 11 ); 

Sma_1 == Sma_1 is still true, but Sma_1 color on chart stay native orange.

Is it expected?
Can I let strategy to create different instances of hosted indicator with same parameters?

Hello,

Thank you for the post.

I wanted to clarify what your sample is demonstrating.

I see that you have two variables for SMA objects and are comparing if they are the same object in your print. You are setting the second instance of the SMA's Brush, but you have not added this instance. Are you seeing that setting the second instance has any effect on the first that was added? While testing what you have provided I do not see there was any change to the added indicator.

Are you expecting that changing your second variable should also affect the first? In this case, I would not expect that setting the second instance of the SMA will affect the first. Can you provide more detail on your test and what you had for the outcome?


I look forward to being of further assistance.

Sma_1 was added on chart.
Sma_2 PlotBrushes were set.
But, Sma_1 colors were changed on chart.

Hello,

Thank you for providing the sample.

Yes, this is the same test as I had completed but I am not seeing the color of the plot change at all.

Can you tell me what version of the platform are you currently using? You can find this in the Help -> About menu. Also, have you tried closing the strategy analyzer and reopening it, is the result the same? Is the result the same from a chart for you as well?

I look forward to being of further assistance.

8.0.9.0 64-bit (Multi-Broker)

Here is short video: https://www.screencast.com/t/D2TP37BG

I've just installed 8.0.10.0 64-bit (Multi-Broker) - same result. Like on video above.

Hello,

Thank you for the reply.

I see you have updated to the current version, I am not seeing anything in the video that would be relevant to cause this. I wanted to check, had you tried doing a clean user folder as a test at this point? I can provide instructions to do this if needed.


I look forward to being of further assistance.

[fx.practic]

Give me instructions.

[NinjaTrader_Jesse]

Hello,

To test the platform with a clean user folder, please do the following:

1. Exit NinjaTrader
2. Open the Documents folder
3. Locate the NinjaTrader 8 folder and Rename it to NinjaTrader 8 Current
4. Locate the installer you had downloaded and re-run it to reinstall NinjaTrader.
5. A new user folder will be generated in place of the one you had renamed.
6. Start NinjaTrader and import the test script you had uploaded to the forum and retest.

Please let me know the results of the test then we can continue from there.

To restore your existing installation after this test, use the following steps:

1. Exit NinjaTrader
2. Open the Documents folder
3. Locate the NinjaTrader 8 folder and remove it
4. Locate the NinaTrader 8 Current folder and rename it to NinjaTrader 8.

I look forward to being of further assistance.

Don't see any difference in behaviour.

Can I return my old NT8 folder back?

[NinjaTrader_Jesse]

Hello,

Thank you for testing that.

You can return to using your original user folder.

After further review I am now able to see this, I am unsure why I was not able to originally but now I can.

It looks like this would be expected in this case as the cache is returning the same instance in the case where the same exact settings are used for both SMA's. Both variables should then point to the cached indicator. To create two different instances using the same parameters/logic, you would likely need to use a second indicator that contains the same logic but is named differently. The indicator instance returned is controlled by the autogenerated code in the bottom of the indicator file.



I look forward to being of further assistance.
