Thank you, s.kinra.
I think I looked at these before. I was looking for a way to have a User Input for the size. I think these are a template drawn on the chart only. I could be wrong that is for sure. LOL
So, to add a User Input for the size is not available?
Thanks again for everything.
James

Hello James,
I think you overlooked it, it indeed has size & you can change it as well, see the attached snapshot for reference (Draw Size highlighted in yellow).
Hope it helps!

Good Morning s.kinra.
I think I misunderstood. Can I use ninjascript to add a user input for the size and color inside the indicator or do they need to create a template from the chart?
Thanks again for your help
James

Hello James,
You can use it similar to other drawing tools from within any indicator, of-course you can use public variables for size / color. Hope it helps!

As an example script:

namespace NinjaTrader.NinjaScript.Indicators
{
    public class TestChartMarkersPlus: Indicator
    {
        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Name = "TestChartMarkersPlus";
                IsOverlay = true;
                Size = 100;
            }
        }

        protected override void OnBarUpdate()
        {
            DrawPlus.Dotp(this, "tag", true, 0, High[0] + 10 * TickSize, Brushes.White, (float)Size, Brushes.Black);
        }

        #region Properties
        [NinjaScriptProperty]
        [Range(1, int.MaxValue)]
        [Display(Name="Size", Order=1, GroupName="Parameters")]
        public int Size
        { get; set; }

    }

Hello Tony,
I use this similar to Current Bar which concatenate the Bar index & this does the price, so basically for every new High I have a new tag & when I call remove based on condition it retains the latest high. However, I don't use them very frequently but things are working for me so far. I don't know your exact issue & that's why I said something seems to be missing, I would suggest you to try removing the draw object in a new indicator with the logic & then you can include it in main code so it keeps things simple & easy for you to understand the behavior. This is how I get the things working for me & I am sure your things would be much more complex. I just try to keep it as simple as I can.

Is it really wise to concatenate the bar index and the price? I am not a professional and I started trading not long ago. But from my little experience, I think this is a case to review.

Hello Dereck39,
There shouldn't be any issues while concatenating bar index & price but it all depends on your needs. The basic idea is to have a unique tag name for each drawing object. I personally prefer counter or bar index with a static string so I can easily identify the object type & still have unique names. Now what exactly you need & where you're getting stuck would need to look into to have a tag name best suited for your requirements. Hope it helps!

Hello Jim,
Happy Holiday.
I have been working again on this project and have a question.
I'm trying to set the size of the ChartMarkerPlus objects and that is good.
I need to have the objects shrink with the candle when zooming out.
Any help would be very much appreciated.
Thank you for your time.
James

Hello laoshr

I would suggest looking at the default drawing objects and how they handled this in their Onrender, the most simple example would be in the chart markers script and the Dot objects OnRender. That shows how to incorporate the bar width to be used for rendering.
