CrossAbove or CrossBelow manual line

[shildebrand324]

Hi all, are there any examples of scripts that shows how to check if a bar has crossed above/below a manually drawn line?

Hello shildebrand324,

Thank you for your post.

This would be possible with a strategy that loops through drawing objects to get their price levels and uses those levels for cross-over conditions to open your position. This would require unlocking the code from the Strategy Builder in order to accomplish. The strategy can then manage the position with the Managed Approach or the Unmanaged Approach.

See the attached example script which demonstrates how to get and print the start price and end price of a manually drawn line.

Managed Approach: https://ninjatrader.com/support/help...d_approach.htm
Unmanaged Approach: https://ninjatrader.com/support/help...d_approach.htm

Note that in NinjaTrader 8, Chart Alerts could be made to easily submit an order when a price crosses over a line drawing object. These orders cannot be tied with ATM strategies, so if you are looking for more robust trading logic, then taking the same approach as described above would be advised.

Is there a way to read the drawing objects in reverse order?

Hello shildebrand324,

Thanks for your note.

No, there are no documented or supported methods for reading the drawing objects in reverse order. The drawing objects are added in a list in the order that they were drawn on the chart.

Since the drawing objects are added to a list, you could possibly consider using C# methods like <List>.Sort to sort the drawing objects list.

Note that we do not provide C# programming education services in our Support department.

That said, you may find more information in this publicly available documentation: https://docs.microsoft.com/en-us/dot...t?view=net-5.0

Let us know if we may further assist.

I guess I'm trying to find a way to get the drawing object closest to the bar

[NinjaTrader_BrandonH]

Hello shildebrand324,

Thanks for your note.

You could assign a unique tag name to the drawing object and then find the drawing object with that specific tag name.

See the first example in this help guide page for more information: https://ninjatrader.com/support/help...rawobjects.htm

Let us know if you have further questions.

Figured out a way to do it use bar time and drawn object time.
