Draw a short line above current price error

[gezy369]

Hello guys, I have a script that does not want to work. It drives me crazy because I cannot find the answer anywere...
I begin in scripting.

My goal is to have a line 16 ticks above the current price and one under the current price.
I don't want a horizontal line accross the chart, but a short one.
Right now I'm trying to diplay a line with no success...

                Calculate = Calculate.OnEachTick;
                IsOverlay = true;
                TicksAbove = 16;
            }
            else if (State == State.Configure)
            {
                tickSize = TickSize;
            }
        }

        protected override void OnBarUpdate()
        {
            if (CurrentBar < 3) return; // Ensure there are enough bars to calculate

            double currentPrice = Close[0];
            double linePrice = currentPrice + (TicksAbove * tickSize);

            // Draw line starting from 3 bars before the current bar and extending to the right
            Draw.Line(this, "LineAbovePrice", false, 3, linePrice, 0, linePrice, Brushes.Green, DashStyleHelper.Solid, 2);
        }
    }
}​

This code generate 2 errors that I cannot solve...

The name 'Draw' does not exist in the current context
The name 'DashStyleHelper' does not exist in the current context

Thanks in advance

Hello gezy369,

The code you provided is missing the default using statements that would be required, you need to regenerate the file and leave the using statements that come with the script at the top of the file.

In the NinjaScript editor right click on your current file and exclude it from compilation. Then right click on the indicators folder and select new indicator and then generate the file. The new file will have the correct using statements and structure and you can begin working in that file again.

Thanks for your answer.
So I just understood that an error can come from another script !ü
Damn boy, still learning haha.

It helped, thx !
