Setting variables for supplementary bar

[yawbus]

Hi,
I am having problem setting variables for my supplementary bar. Let me give an easy example below to show what I mean:

#region Variables
private DataSeries vol5m;
private DataSeries vol10m;
#endregion


protected override void Initialize()
{
vol5m= new DataSeries(this);
vol10m= new DataSeries(this);

Add(PeriodType.Minute, 10);

CalculateOnBarClose = true;
}


protected override void OnBarUpdate()
{

if (BarsInProgress == 0)
{
vol5m.Set(Volume[0]);
}

if (BarsInProgress == 1)
{
vol10m.Set(Volumes[1][0]);

Print("Barsinprogress 1 " + Time[0] + " " + vol10m[0] + " " + vol10m[1] + " " + vol10m[2] + " " + vol10m[3] + " " + vol10m[4] + " " + vol10m[5] + " ");
}

}

When I set the primary bar to 5 minute, here is the output:

Barsinprogress 1 22/7/2014 10:00:00 AM 4707 2101 6281 3973 9424 2779
Barsinprogress 1 22/7/2014 10:10:00 AM 6380 2569 4707 2101 6281 3973
Barsinprogress 1 22/7/2014 10:20:00 AM 4481 2947 6380 2569 4707 2101


Take the output from 10am as an example, the vol10m[0] is "4707". I expected the "4707" to become vol10m[1] when the bar was next updated at 10:10am. However, as you can see from the 10:10am output that the "4707" is actually vol10m[2].

Basically whatever number that is set as vol10m[0] will become vol10m[2] when the bar gets updated next, and then become vol10m[4] when it gets updated again. I don't know where the numbers for vol10m[1], vol10m[3], vol10m[5],... etc come from, but they should not be there. (It is easy to verify that the vol10m[1], vol10m[3] etc should not be there because I can simply plot a 10-minute chart to check the volume)

This is just a simple example to illustrate the problem I have been trying to solve for the past week. Would anyone be able to help ?

Thanks very much.

Hello Yawbus,

Thank you for your post.

There is a syncing conflict here with the dataseries.
You are syncing both data series to the primary time frame from when you are adding the indicator to the chart. The additional index that you are seeing is a "filler' bar to account for the additional bar from the 5m time frame

You can take a look at the sample below on syncing to a different time frame

Let me know if I can be of further assistance.

Thanks for your help, Cal.

I can now sync DataSeries correctly to the secondary bar. However I am still having problem syncing BoolSeries correctly to the secondary bar. In the following example:

protected override void OnBarUpdate()
{
if (secondarySeries == null)
{
secondarySeries = new BoolSeries(?));
}

if my secondarySeries is now a BoolSeries, I cannot think of an indicator to replace the "?", is there one ?

Thanks again.

Yawbus,

You would sync the same way you did this with the dataseries
