Hello,
How could one be alerted when price crossed a ray and then have that ray from the chart?
Thanks

Hello CaptainAmericaXX,

Thanks for your post.

I suspect your question is incomplete, are you asking to be notified by alert sound when price crosses a ray and then once it has crossed to remove the ray?

Sorry Paul, I wasn't specific. So programmatically how would one determine when price had crossed the ray? I created a ray and I was hoping that I could see the data of the ray per bar with the Data box, but there is no ray data. I want to set a bool true once price has crossed the ray.
Thanks.
PS. I just realized that this was a NT 8 thread. I need info on NT 7 rays. I found information on iSlope in NT 8. I believe this is the answer to my question. Is there something comparable in NT7?
PPS. So I realized I could just find slope m = y2 - y1 / x2 - x1 and create a variable. Had to dust off my preAlgebra from 80 years ago. Might need some more help, but I'm ok for now. Could use some pointers in how to end a ray at some point.
Thanks.

Hello CaptainAmericaXX,

Thanks for your post.

We will move your post to a new thread in NT7 indicator development forum.

For NT7 the same Slope() method is available, here is a link: https://ninjatrader.com/support/help...nt7/?slope.htm

To remove the ray (or any draw object) you can use RemoveDrawObject() where all you need to do is provide the tag name of the ray, reference: https://ninjatrader.com/support/help...drawobject.htm
