Divergence Spotter NT8 on strategy

[bergimax]

Hi,
I want to build a strategy based on Divergence Spotter for NT8, and I saw this: https://ninjatraderecosystem.com/use...e-spotter-nt8/ but, if i use this indicator the strategy never gets the signal from this indicator.
Looks like it works only in the chart. How can i use this indicator in the strategy?

Thank's,
Massimo

Hello bergimax,

Thank you for the post.

Are you using the strategy builder or manually coding? The easiest way to see whats happening would be to use a print and output the plot you are using to see what values are being reported.

I would otherwise need to see how you used the indicator to get a better idea of what may be happening. If you can provide an export sample that would be helpful.

I look forward to being of further assistance.

Hi Jesse, thank's for the replay. I'm using manually coding, and using this prints i got always 0:

Print("DivergenceSpotterV2().Entry[1]: " + DivergenceSpotterV2().Entry[1]);
Print("DivergenceSpotterV2().Entry[0]: " + DivergenceSpotterV2().Entry[0]);
Print("DivergenceSpotterV2().IndicatorType: " + DivergenceSpotterV2().IndicatorType);
Print("DivergenceSpotterV2().SellSignal[0]: " + DivergenceSpotterV2().SellSignal[0]);
Print("DivergenceSpotterV2().BuySignal[0]: " + DivergenceSpotterV2().BuySignal[0]);

I use the indicator in this way:
if( DivergenceSpotterV2().Entry[0] == 1){
//Do something
}

I tried all of the variable used in the Print, but it never works.
I also tried to change the indicator type in this way:

DivergenceSpotterV2().IndicatorType = DivergenceSpotter_IndicatorType.RSI;

Where am i wrong?
Thank's for the help,
Massimo

Hello bergimax,

Thank you for the reply.

I don't necessarily see anything wrong there. Could you try doing the following test, this will both test that you have the correct syntax and also produce a sample.

From the control center open the strategy builder.
As a action, Print the DivergenceSpotterV2 plot
Run the script and see if its still 0. If so I can use the same steps to test that on my end.

Can you also link which specific file you downloaded from the app share again? It looks like the link you posted was cut off, you may need to Control + Shift + V to paste without formatting.

I look forward to being of further assistance.

Ok Jesse, i did the tests and this is what i found that using the strategy builder it doesn't work anyway, the values are everytime 0.
- Doing the manual load of the indicator on the chart (not with strategy), the indicator doesn't show the entry point. If i change the plot, for example from Macd to BOP, it start working and showing the entry point. If i come back, from BOP to MACD, it show the entry point based on the MACD.

Hello bergimax,

Thank you for the reply.

I took a look at the indicator and from what I can see the 0 is controlled by both how the plots are being set and also this logic:

else if (State == State.Configure)
{
if(RunInit && ChartControl != null)
{
[B]RunInit[/B]=false;
IsAutoScale = false;
}
}


if(RunInit) return;

Commenting out the if(RunInit) return; was required for me to see anything happen. I did not invest time into figuring out what that was specifically used for but that seems to allow it to print not 0.

Another factor is how the plots are infrequently set. You will still see 0's or a price value depending if the plot had been set on that bar. You could replace the following:

SellSignal[0] = 0;
BuySignal[0] = 0;

with

SellSignal[0] = SellSignal[1];
BuySignal[0] = BuySignal[1];

If you wanted to persist the plot values to give a constant plot or constant price output from the plot.

Perfect, now it works! Thank you very much.

Have a nice weekend,

Hello, I have been trying to do the same thing for a while now and just cant seem to get it to spit out numerical value =1
Anyway to have a better guide or maybe just a new script as a whole that I can import?

Hi Jesse,

I'm trying to get a simple strategy to paint the bar if the value is above 0, showing a divergence.

I removed the

if(RunInit) return;

into the indicator but still does not work for me. The chart plots the values correctly, showing divergences as greater than 0 but the strategy does not detect any values greater than 0.
Any idea?

Thanks!

EDIT:
There was the code

if(RunInit) return;

under the OnBarUpdate that I didnt see. I removed that and works now
