Short horizontal line (~5 bars ago)

[kamix265]

HI,
Firstly I have to apologize for my bad english.

I have a problem with rewrite script from NT7 to NT8. I need a short horizontal line like that on a picture.

                sum = priorSum + Input[0] - (CurrentBar >= Period ? Input[Period] : 0);
                Value[0] = sum / (CurrentBar < Period ? CurrentBar + 1 : Period);
            }
        }

If you have any ideas, I would be grateful for help.

Hello kamix265,

Thank you for the post, and welcome to the NinjaTrader support forum.

First, make sure that you have barsBack set up at the class level as a public property.

At the class level:

[Range(1, int.MaxValue), NinjaScriptProperty]
		[Display(ResourceType = typeof(Custom.Resource), Name = "barsBack", GroupName = "NinjaScriptParameters", Order = 0)]
		public int barsBack
		{ get; set; }

The other thing you will need to change is the Color smaLineColor property. The Draw.Line method takes a Brush object in NinjaTrader 8 instead of a Color. Also, make sure to pass the NinjaScript owner.

Brush smaLineColor            = Brushes.Orange;

...

Draw.Line(this, "HorizontalSMA", 0, Value[0], barsBack ,Value[0], smaLineColor);

The constructor for NT8's Draw.Line() can be found below:

Please let me know if I can assist further.

Hi, when I use this code, I am not able to "drag and drop" the short HorizontalSMA line to another panel.... I have it as a HorizontalSMA (15-min) in panel 3, and want to move it to my (1-min) chart in Panel 1... The line shows as "locked"... when I unlock it, it still doesn't move to panel 1, and also when I change it in properties it doesn't move to any other panel.

Dragging to another panel (with different time frame) works with the "regular" SMA indicator, but I can't get it to work with this modified version.

**** If you could show me how to modify the HorizontalSMA so that it calculates on the 15-min time frame (inside the 1-min chart) that would be ideal!!! *****

Please help! Thank you

Hello ldanenberg,

To show the drawing object in a different panel, you would need to use DrawOnPricePanel false, and assign the indicator Panel to the panel you would like the drawn object in.

Hi Chelsea, this will not work since I have 2 price panels.... a 1-min chart, and a 15-min chart. I would like to draw the 15-min indicator, on the 1-min chart.
