indicator bid / ask volume help

[safetrading]

I'm would like to add bid / ask data to a current indicator. Does anyone know how I can address this data within my existing formula?

Thanks for your time.

Try GetCurrentBid() and GetCurrentAsk(). You may also want to build your own Level II book. Check this reference sample out: http://www.ninjatrader-support.com/v...ead.php?t=3478

Thanks for the reply. I tried your suggestion above and also looked at the referenced zip file, but to no avail. Here is the line I edited with your suggestion above;

UpperBand.Set(Bollinger(GetCurrentAsk()-GetCurrentBid().Avg, 2, 34).Upper[0]);

This line gives me this error; CS0117, which states;

'double' does not contain a definition for 'Avg'

Any thoughts?

You can't do it like that because Get() are not DataSeries. You can only call DataSeries objects from that parameter in the Bollinger(). If you wish to still call this spread calculation you will need to make your own DataSeries containing that calculation. Please see the help guide article for DataSeries objects.

Thanks Josh, I'll look up the data series.
