Custom Drawing Tool HorizontalLines

[Gianpiero]

Hi guys!

I want to code a custom drawing tool that draws not only one horizontal line when I click the high or the low of a bar with the crosshair but multiple horizontal lines around these points.

I looked at "Using SharpDX for Custom Chart Rendering" in NinjaScript Reference Guide. I would like to know if this kind of tool needs ShardDX. Could it be coded in standard NinjaScript?

I also read two or three other users' solutions for plotting labeled lines, but I'm not interested in labels, just in multiple horizontal lines above and below a price.

So, I started stripping unnecessary text-handling code but ended up in a mess. I still need to sort out the overall code structure of this tool, meaning understanding where to create my logic and custom resources like brushes and strokes and how to integrate it into the Drawing Panel of NinjaTrader.

Last but not least, how do we configure it to be used and exported?
What structure should the final .zip file have?

Hello Gianpiero,

Yes, all custom drawing tools would be rendered with SharpDX in OnRender().

The TrendLines and Fibonacci drawing tools may give you some ideas about rendering multiple lines with a given set of anchor points.

Below is a link to an exported custom drawing tool.

The final .zip should have the structure that NinjaTrader creates when it is exported from NinjaTrader.

To export a NinjaTrader 8 NinjaScript so this can be shared and imported by the recipient do the following:

1. Click Tools -> Export -> NinjaScript...
2. Click the 'add' link -> check the box(es) for the script(s) and reference(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>

Thank you a lot!

I'll look into this.

PS - The last link doesn't work for me. I get a page Not Found message.

I have trouble finding the code implementing the TrendLines and Fibonacci drawing tools. I would appreciate your help very much, given that I need to plot a set of horizontal lines offset ± four ticks above and below, starting from the price where I draw the first line horizontal line when I click the High or the Low of the bar (the Anchor Y of the object).

[Gianpiero]

I found them. Usually, I don't mess around with code with a @ in front of its name.

Hello Gianpiero,

The links in my post are working on my end.

May I confirm you are clicking the link and not copying and pasting the link? (It's abbreviated on the forum)

If you right-click the link and open in a new tab does it open correctly?

In the @FibonacciTools script, the rendering of the lines is on lines 243 to 274.
In the @TrendChannel script, the rendering of lines is on lines 535 to 844.

Thanks again!

I guess my browser lands on a different page from yours. I get Error 404, alias not found, from a web page in Italian, which I hardly think matches yours

Hello Gianpiero,

Thank you for letting me know you have the language set to italian. I was sending the link to the english page, though I still would expect that to load.

Below is a generic link to the page.
