getting error

Bill,

Did you create the first indicator for the UpDownTradeVolumeNV?

Additionally, are you using the correct name for it? The error indicates that the current name UpDownTradeVolumeNV does not exist in your indicators

Hello Bill,

Thank you for your note.

I am not aware of UpDownTradeVolumeNV.

Is this a custom indicator that you have?

Hi,
I am new to programming and writing my first program getting the error.

UpDownTradeVolumeNV() does not exit in the current context...what can be the problem..
actually code :

protected override void OnBarUpdate()
{
UpVol.Set( UpDownTradeVolumeNV().UpVolume[0] );
DownVol.Set( -UpDownTradeVolumeNV().DownVolume[0] );
ZeroLine.Set( 0.00 );
}


Thanks in advance.

Bill
