Draw Lines within a bar

[kaywai]

Hi,

I'd like to Draw Horizontal lines within a bar. Currently, using the Draw.Line function, the line is drawn from the middle of the current bar to the middle of the future bar.

I've attached an example of what I'm trying to do. I'm referring to the Red and Blue lines in the attachment (file: Capure. I've also attached an example of what I'm getting now (File: SPY (Daily) 2022_02_12 (4_20_22 PM)).

Is there any way I can achieve my desired result?

Regards

Hello kaywai,

Thanks for your post.

You could consider using Median[0] or (High[0] + Low[0]) /2 for the Y coordinates when calling the drawing method.

See the help guide documentation below for more information.

Hi BrandonH,

Thank you for you reply but that isn't what i'm looking for.

What i would like is for the horizontal line to be drawn across the width of the current bar or candle. Currently when i use the draw.line function, it is drawing the horizontal from the second half of the current bar or the current candle to the space that will be taken up by first half of the future bar of candle.

The capture file is not from a NT8 chart but I would like to achieve a similar result. The second chart is what i'm getting from NT8 right now which isn't what I really want. On the X-axis of Draw.Line, I'm using 0 for the startBarsAgo and 1 for the endBarsAgo.

Hello kaywai,

Thanks for your note.

I understand that you would like to have a horizontal line drawn across the width of a bar similar to the first image you shared in your initial post.

To accomplish this, you would need to use custom rendering with SharpDX in OnRender() instead of Drawing objects such as Draw.Line().

Drawing objects will snap to the anchor which is in the center of the bar. Custom rendering with SharpDX in OnRender() would allow you to calculate the exact location you want your line placed on a chart.

See the SampleCustomRender indicator that comes default with NinjaTrader for examples of custom rendering with SharpDX. To view the SampleCustomRender indicator code, open a New > NinjaScript Editor window, open the Indicators folder in the Editor, and select the SampleCustomRender script.

Also, see the help guide documentation below.
