Crosing line

[vladko]

Hello.

How to track crossing price and manually drawn line (Ray or ExtendedLine)?

Hello Vladko,

Thank you for your note.

You would need to take a look at the DrawObjects collection. This will show you how to loop through the list of DrawObjects in the chart and get the relevant information for that object.

Let me know if I can be of further assistance.

Ok, I found my line

foreach (IDrawObject draw in DrawObjects)
{	
  if (draw is IRay)
  {
     IRay ray=(IRay)draw;
  ....
  }
}

How to check crossing Close[0] and ray?

Vladko,

These are all the available properties of the ray you can get -

However, the issue here is that you won't get the continuing Ray line directly, meaning the part of the line after the second anchor.

You would need to calculate out the slope of the line and what the Y value would be in relation to the bar that it would be processed on, such as Rise over Run.

Code:

HI Vladko

Cal, giving great advice as NT staff always give in the Forum, is saying you would need to work out the equation of the ray. This comes down to Cartesian coordinates and line equations. I have done exactly this myself recently with one of my Ninja methods and it works a treat.

If you need any help with the math, just put a request in this thread and I'll post the necessary equations.

Cheers.
