drawing a line above or below a period with the conditions met

I want to draw a line above or below a period with the conditions met.

Lets say if a SMA cross another SMA, then draw something to show the beginning till the end of this condition is true.

You can use DrawLine() and programmatically do it inside your NinjaScript Strategy.

How do you do it to draw a line from the first bar that met the condition till the last bar that met the condition?

Is there a document for this DrawLine() function?

You choose the startBar and the endBar parameters for the DrawLine to decide where it draws. You need to program logic to decide where the start bar is and where the end bar is. http://www.ninjatrader-support.com/H.../DrawLine.html
