NT8 Trend Strategy-Indicator

[i2w8am9ii2]

Hello,

I'm trying to create an indicator (starting from the Strategy Builder), that will give me a signal when the following exists:

* Current 15 minute price bar is above previous 15 minute price bar ... and/or
* Current 30 minute price bar is above previous 30 minute price bar... and/or
* Current 60 minute price bar is above previous 60 minute price bar... and/or
* Current Daily price bar is above previous Daily price bar... and/or
* Current Weekly price bar is above previous Weekly price bar... and/or
* Current Monthly price bar is above previous Monthly price bar... THEN

Draw a blue upward angling arrow on chart... OR
If two or more of the above exist, draw two blue arrows

The inverse setups would draw a brown downward arrow (or two) on the chart

My question is, is this code in any way correct? A starting point? Completely wrong?

I know that I don't have the code added to draw the second arrow yet; I'll try to figure that out later.

Later on, I also plan to have a "current price bar broke out beyond previous price bar" code set that will draw different colored arrows.

Hello i2w8am9ii2,

The issue that I see with this is that Times[1][1] is called but there is no check that CurrentBars[1] has at least 2 bars..
This could cause an indexing error if on the first primary bar there are not 2 previous months of month bars that have processed. The same is true for all of the added series where the previous bar is being referenced.

What version of NinjaTrader are you using? (Help > About)


That said, the code does not reference any price data. You are not comparing the Close[0] of the current bar to be greater than Closes[6][1] to find if the current bars close is greater than the 15 minute series previous close.

Below is a public link to a forum post with helpful information about getting started with NinjaScript that includes a link to the Strategy Builder 301 course.

As a tip, to export a NinjaTrader 8 NinjaScript so this can be shared do the following:

1. Click Tools -> Export -> NinjaScript...
2. Click the 'add' link -> check the box(es) for the script(s) you want to include
3. Click the 'Export' button
4. Enter a unique name for the file in the value for 'File name:'
5. Choose a save location -> click Save
6. Click OK to clear the export location message

By default your exported file will be in the following location:

• (My) Documents/NinjaTrader 8/bin/Custom/ExportNinjaScript/<export_file_name.zip>

Hi Chelsea,

Thanks for the links and for the info.

I am using Ninjatrader version 8.0.15.1 64-bit

Attached is a zip file of my exported NT8 Strategy in it's initial stage.

Hello i2w8am9ii2,

I just want to re-iterate that you are comparing the time of day of one series with another series. You are not comparing the close prices.

In the condition builder this would be in the Price section.

Hi Chelsea,

Okay, I understand now.

I made the changes.

Attached is a screenshot of the code and attached also is a new exported zip file (exported from Strategy Builder).

Hello i2w8am9ii2,

Is there an issue with the new code?

If so what is the issue you are having?

Are you unable to find the drawing objects on the last bar where the condition has occurred at a y value (price) of 0?

[i2w8am9ii2]

Hi Chelsea,

Thanks for checking back.

I am going to test it out soon, I haven't had a chance to do so yet.

In the meanwhile, I want to use some custom arrows for the drawing objects.

Is it possible to import custom graphics (arrows) to use for drawing objects? If so, how would I do so?

Attached is a screenshot of the custom drawing objects that I want to use.

Hi Chelsea,

I turned the code into a NT8 indicator and compiled it. Originally there was one closing brace missing, so I found out where it was needed then added it.

Then the indicator compiled without errors.

Attached is the indicator zip file.

I did not test it out on my charts yet; I will do so soon.

In the meanwhile, if you find anything wrong with my code or logic, please let me know.

Thanks,

Hello i2w8am9ii2,

Thank you for your response.

The code looks correct at this point. I do want to point out that the current state of the code is that all conditions in each set must be true. Are you still working on breaking the conditions down to draw different items depending on the number of true conditions?

Attached is an example of drawing an image through NinjaScript. There are advanced functions in the code, please let me know if you have any questions.

Hi Patrick,

Thanks for your reply and for the attached sample .cs file.

I could not comprehend the .cs file; it has code that I'm not familiar with. I'm just learning C# and NinjaScript and so I'm creating only very simple indicators at this time.

Yes, you are right, the current code was that all conditions in each set must be true, and I changed that to be that either condition can be true.

I changed to code to draw a triangle if 'either' condition was met, then tested it again, but still, it has not yet once drawn a triangle on the chart when it was supposed to.

Then I tried changing the Drawing Object code and tested it again, but still, it is not drawing a triangle on the chart.

Attached are screenshots of the code and the changes that I made.

The black arrows that I drew on the chart screenshot show where an arrow should have been drawn.

Attached also is a zip file with the new version of the indicator.

Please advise on why the drawing object is not drawing the object.

Thanks,

Hello i2w8am9ii2,

Thank you for your response.

Your conditions are set up properly. I would ask you to use the Global Cross Hair on each of the charts that are used in the condition to verify they are in the proper position (all greater than or less than prior bar).

You can find details on the Cross Hair at the following link: https://ninjatrader.com/support/help...cross_hair.htm

Please let me know if you have any questions.

Hi Patrick,

Thanks for the info and link.

I will try it out.
