Help with inner workings of FloatSeries Class

[8DTK8]

I have been having decent success working with adding a FloatSeries Class with the excellent samples in http://www.ninjatrader.com/support/f...ead.php?t=4991 .

One thing that I have come across that I had quite the time figuring out is the nature of the [bars ago] suffix and what it's actually doing.

I have an indicator that writes to the float series every on bar update.

The float series contains values that are held constant with an occasional change. Here's where it gets interesting and has been the source of headache.

When I compare this.myFloatSeries[0] to this.myFloatSeries[1], it produces the last two values that are different.

So if the series contains:
bars ago & value
[0] 5
[1] 5
[2] 5
[3] 7
[4] 7
[5] 7
[6] 7
[7] 9
[8] 9

this.myFloatSeries[0] and this.myFloatSeries[1] returns 5 and 7
similarly
this.myFloatSeries[1] and this.myFloatSeries[2] seem to return 7 and 9

It seems to be ignoring all repeated values.

If someone could tell me if this is what it is supposed to do or if my amateur/novice programming status has finally caught up with me, I would greatly appreciate it.

Thanks.

Hi 8DTK8, the accessing of the values via the barsAgo index should be the same for any dataSeries type object - http://www.ninjatrader-support.com/H...iesObject.html

When are you printing those values from the code to debug?

Which CalculateOnBarClose setting are you working with?

Hmmm, this is the same kind of behavior I have been experiencing and posting questions about. I finally shelved the idea because I couldn't get it to work in anything close to the way I was expecting.

It seems like our issues are very similar; I would put a value in 0 (say 12) and then the next bar put a value in 0 (say 55) and read 1 and instead of getting the number I put in 0 (12) last bar, I would get a seemingly random number that I could not tie to anything.

This is a bit of a late follow up, but after a bit of struggling, I figured out what I was doing wrong. It was my variable declaration that was flawed not the way the FloatSeries was being created.

Thank you for your help Bertrand. The link was helpful.
