DrawFibonacciExtensions Error

[Ironleg]

Hi
I am just simply trying to place a Fibonachi Extension EUR/USD, but get following error:
11/12/2008 22:38:17 Default Error on calling the 'OnBarUpdate' method for indicator 'MyZigZag' on bar 0: MyZigZag.DrawFibonacciExtensions: anchor1BarsAgo out of valid range 0 through 0, was 38.

My Code:
DrawFibonacciExtensions("tag1", true, 38, 1.3305, 31, 1.334, 28, 1.3309);

Please help

Thank you very much!

Your method seems to be executed on bar0, which doesn't make sense I guess.

It does... look at the link above, when you reload the script it will call this method on every OnBarUpdate from the start, but from the start I don't have enough bars, so if I do something like this

protected override void OnBarUpdate()
{
if (CurrentBar < 50)
return;

DrawFobo();
}

It will not throw an error, I just need no less than 42 bars drawn in the case of the method in my first post

Thank you, I am new to NinjaTrader, but being a .Net C# developer, love it so far very very much :)

Here is another question:

Is it possible to access drawn objects like FiboExtension for it's levels via name or id?

[NinjaTrader_Josh]

We do not support accessing draw objects through NinjaScript. If you want to remember it's values you should store calculations that determine them for use later on.

it's a pity... it would've been a killer feature, not only in regards of Fibs, but for all objects on the chart, will have to find a work around.
