how to draw horizontal line in custom indicator

[trader252]

Hi,
I'm trying to create a custom indicator that has 2 horizontal lines (1 line above the current price and 1 line below the current price). Similar to pivot lines. I've attached a screenshot of how I want it to look.

Questions:
1. What method/function do I call to draw the lines?
2. Where do I make the function call to draw the lines? OnBarUpdate()?
2. How can I update/redraw the lines only when price cross above or below the lines?

thanks

Hello trader252,

Thanks for your questions.

1. What method/function do I call to draw the lines?

All Drawing methods can be found here - https://ninjatrader.com/support/help...ml?drawing.htm

2. Where do I make the function call to draw the lines? OnBarUpdate()?

Yes, Draw methods can be called in OnBarUpdate.

3. How can I update/redraw the lines only when price cross above or below the lines?

The Drawing method can be called again with the same tag parameter, and the drawing object will be updated. (If you append CurrentBar to the tag, you will have a unique tag per bar, and thus unique drawing objects per bar.

If you are new to NinjaScript, you may also wish to experiment using the Strategy Builder to create some simple drawing logic. The resulting syntax can be viewed with the View Code button.
