GetValueAt() - is this expected

[Jack22]

I am seeing a difference between what OnBarUpdate shows as the value for Input versus what OnRender shows for Input--OnRender uses GetValueAt(). I also created iInput and set this value to Input in OnBarUpdate, which if pulled the same way Input (GetValueAt()) in OnRender, I am able to pull the correct values.

Steps to reproduce:
1. Create new chart
2. Load attached indicator
3. Change the input for the indicator to CCI(14)
4. Look at the output window

The output is as follows on OnBarUpdate:
OnBarUpdate***
Input: 50.8486082824375 (this is the correct value of CCI(14))
iInput: 50.8486082824375 (this is the correct value of CCI(14))

The output is as follows on OnRender:
OnRender****
Indicator Input
Input: 2708.5 (this is NOT the correct value of CCI(14))--it looks like Input.GetValueAt() always pulls the value from the Bars
iInput: 50.8486082824375 (this is the correct value of CCI(14))

Is this an expected behavior?

Hello Jack22,

Thank you for your note.

To confirm, you are showing that when using an indicator as the input series for this indicator, Input.GetValueAt() is not returning the value of the indicator and is returning the Close[0] price (or Bars.GetClose()) instead? Is this correct?

I will test and if I am able to reproduce I will report to our development.

I will let you know what I find.

That's correct

Hello Jack22,

Our development pointed out something I overlooked.

From the help guide:

"Tip: If called directly from the instance of the NinjaScript object, the value which is returned corresponds to the input series the object is running. (e.g., Close, High, Low, SMA, etc.). If you're attempting to obtain another indicator value, you will need to pull this from the calculated indicator Value or Plot:
SMA(20).GetValueAt(123); // bar value
SMA(20).Values[0].GetValueAt(123); // indicator value"

https://ninjatrader.com/support/helpGuides/nt8/en-us/getvalueat.htm

Use:

(Input as Indicator).Values[0].GetValueAt(Bars.Count - bar)

Just tested and that solved my issues. Thanks. Can you add that as an example in the help documentation so it's a little more clear for anyone else who runs into this?

Hello Jack22,

I will send your request for this example to be added to the help guide.

Let me know if I may further assist.
