Drawing Tools - Arrows

[dmking]

Has anyone come across anything tha lets you draw smaller arrow heads than what's offered with the current arrow offered in the drawing tool. The arrow head is huge!

I guess an alternative would be to use Snagit to capture a chart and uses their drawing tools!

Seems like this would be easy to address by offering a few different arrow head sizes.

TIA

Hello dmking,

Thanks for your post.

I will submit a feature request to development to be able to adjust the size of drawing objects.

I am testing out NT8 and have created a simple script that draws an arrow whenever there is a cross above the swing high. However I am only getting 1 arrow (most recent) whereas I would like to see all the recent arrows.

Thanks

They need unique names...

Draw.ArrowUp(this, "MyCustomStrategy1 Arrow up"+CurrentBar, ...

http://ninjatrader.com/support/helpGuides/nt8/en-us/?arrowup.htm

tag
A user defined unique id used to reference the draw object. For example, if you pass in a value of "myTag", each time this tag is used, the same draw object is modified. If unique tags are used each time, a new draw object will be created each time.

[brucelevy]

So is it possible for them not to be unique so it displays all of them?

[sledge]

No. Not on this platform.

[brucelevy]

That does not make any sense, maybe I am not explaining myself correctly.

I want to display an up arrow everytime the close crosses above the prior swing high.

I mentioned this below based on your code:

Draw.ArrowUp(this, "MyCustomStrategy1 Arrow up"[B]+CurrentBar,[/B] ...

This would make each one "unique" and NT will display them all.

They can not be named the same thing. If they are named the same thing, you will only see the latest one, as you have seen.

[brucelevy]

Thanks Sledge, I see I had overlooked +CurrentBar

[koganam]

Your current code answers that question, so why do you ask it?

In your current code, the tags are not unique. Does it show them all?

It's a valid question with or without the current code.

There could be some checkbox somewhere in the not so vast (but somewhat obscure) options in NT... especially NT8...

Granted, but the current code does exist, so it is pointless asking whether it is possible to use that current code to show that which it has already shown that it will not. There is one absolute given with a computer program: if the program is not using randomized elements, then it is deterministic in an absolute sense; and will always produce the same result from the same inputs. As a matter of fact, if it does not, that in itself points to an almost certain hardware issue.

Well, I'm somewhat of a "hacker"... so there are always some sort of possibilities.

Don't make me go OllyDbg on this... I'll find a back door mod...

Well, if you want to mod the NT files themselves, to find the Draw() code and modify it so that it no longer sees the tag as a unique identifier ... Just remember that this is not NT8, so you cannot see the source code directly.

Though your question is answered already there is a private bool I use to differentiate between present arrows and past arrows. That allows me to only have the present arrows show up (which is what I usually prefer) but now and then I want to see the past ones as well. I also added RemoveDrawObject for the opposite condition which is useful when the condition changes within the same bar. Anyway, may or may not be something useful for you, but I thought I'd mention it.

MY CONDITION
{
DrawArrowUp("Arrow Up", false, 0, Low[0] - drawplace *TickSize, upsym);
RemoveDrawObject ("Arrow Down");

if (showpastArrows_On) DrawArrowUp("Arrow Up" + CurrentBar, false, 0, Low[0] - drawplace *TickSize, upsym);
}
