Dataseries or Array not linked to bars

[tchapman]

Hi,

Is there a way to create an array or dataseries that is not linked to the bars object, ie needs to have a value for every bar.

I only want a value to be set when an event occurs then be able to look back at the last X number of events.

Thanks,

Tim

I can not vouch for a data series, but arrays are generated in "NinjaScript" he same way they are in C# - it is possible, and the C# documentation can explain you the language ;)

Thanks for the reply NetTecture.

I got this working. So for the benefit of anyone else reading this here is how i did it.

The only caveat i'll put on this is that i'm not a c# programmer so there may be a more correct or efficient way of doing this. However problem solved none the less.

Declarations:
//Added the following
using System.Collections;

Variables
private int[] biasarray;
private Queue biasqueue;

Initialize
// Initialize a queue of size 5 and array of size 6and type integer
biasqueue = new Queue(5);
biasarray = new int[6] {0,0,0,0,0,0};

OnBarUpdate
// Added the value to the queue using
biasqueue.Enqueue(somevalue)

// The QueueName.TrimtoSize() funtion is supposed to trim the queue to the initilised length however i couldnt get it to work so I used the following to trim the queue to the correct length

if (biasqueue.Count > 5)
{
biasqueue.Dequeue();
}

// I then moved the queue to an array so I could read each of the values. I was essentially looking for bias change patterns by assigning HH HL LH LL each a value and matching the pattern using a case statement and displaying an alert.

// To move the queue to an array i used this statement

biasqueue.CopyTo(biasarray, 0);

Cheers,

Thanks I was having the same problem !

Can you explain why you needed to fill the queue and then copy to an array instead of filling the array directly ? because of the size limit on the array and no dequeue function to trim it down ?

Thanks

Reading a bit more

I think one could have used a dataseries class as well to store the values that is being stored in the array ?

Has anyone tried that ?
