VolumeUpDown : Clarification/Explaination

[jkt1120]

(This is an example from the Ninjatrader Forum)

Please try VolumeUpDown().Values[0][0] and VolumeUpDown().Values[1][0].

[0][0] being up.
[1][0] being down.


In the VolumeUpDown call in Ninjatrader 7, could you please give me an explanation of how the values passed are being are being used and what is returned?

For example when I pass a [0][0] will my return value only be the current bar's Up volume ?
And when I pass a [1][0] will my return value only be the current bars Down volume ?

Thanks Jack

Hello jkt1120,

Thank you for your post.

Values refers to a plot added to the script using the Add() method. Since the first plot added to the script is UpVolume, you would use Values[0][0] to get a value for the Up Volume. The second plot added to the script is DownVolume. You would use Values[1][0] to get a value for the Down Volume.

See the help guide documentation below for more information.

Values - https://ninjatrader.com/support/help...nt7/values.htm

If you view the source code for the VolumeUpDown indicator by selecting Tools > Edit NinjaScript > Indicator > VolumeUpDown, we are able to see which plot is added first and how the plots are referred to using Values. In the script, if the close is greater than the open, the script assigns Volume[0] to Values[0] and resets Values[1]. Otherwise, Values[1] is assigned the value Volume[0] and Values[0] is reset.

Please let us know if we may further assist.
