How to 'recognize' drawn arrows in code

[arbuthnot]

Hi everyone

I have no idea how to go about this but I have a feeling this may be possible.

What I'd like to have is some code that would detect all arrows drawn manually on a chart (and then, for example, calculate the distance to the next close, something like this).

Any ideas would be much appreciated.

Hi arbuthnot,

To find all arrows on a chart.

foreach(IDrawObject draw in DrawObjects)
{
if (draw.DrawType == DrawType.ArrowDown)
{
IArrowDown dArrow;
dArrow = (IArrowDown) draw;
if (dArrow == null)
return;
Print(dArrow.Y);
}
}

Once you have two objects you can use the Y or Time and do your subtraction.

Thanks very much, Chelsea, for telling me this is possible and how to go about it.

I'll try to set this up as an indicator over the next day or two. If I have nay further questions about this, I'll post back here.

Much obliged.

You asked specifically for manually drawn objects, so you are missing a filter.

...
if (draw.DrawType == DrawType.ArrowDown[COLOR="Blue"] && draw.UserDrawn[/COLOR]){//...}

Much obliged, Koganam! I'll incorporate your code.

Cheers.
