Set back an Array to Null Value

[baba123]

I want to set back an array to null value on each OnBarUpdate calling.
How do you do that ?

baba123,

Can you clarify how you're using the array? Is this a custom array or do you mean a data series?

If you're using a basic data series, you can use:

myDataSeries.Reset();

Please let me know if that's not what you meant.

What type of array is it?
What was your intital declaration of said array?

[baba123]

It is a custom array : int[ ] MyArray =new int {0,0,0}

To be more specific I want to clear all the value in my array on each bar update

Then just declare the array again on each OnBarUpdate() pass. Declaring an array with the same name as an existing array replaces the existing array.

If you just want to reset all the elements of the array to zero, use Array.Clear(MyArray, 0, MyArray.Length).
