question about some special variables

[emcdowe]

Dear NJ support.

If I want to create an indicator/strategy by referring to the following variables,. how to do that?

for exmaple, TRIN indictor,

TRIN = (NYSE Advance Issues - NYSE Decline Issues)/ (NYSE Advance Volume - NYSE Decline Volume)


- $UVOL (NYSE Advance Volume)
- $UVOL/Q (NASDAQ Advance Volume)
- $DVOL (NYSE Decline Volume)
- $DVOL/Q (Nasdaq Decline Volume)
- $ADVN (NYSE Advance Issues)
- $ADVN/Q (NASDAQ Advance Issues)
- $DECN (NYSE Decline Issues)
- $DECN/Q (NASDAQ Decline Issues)

How to refer to the above variables in a newly created indicator?

Thanks.

emcdowe, you could Add() those instruments as new bars objects to your Initialize() in the indicator (only for NT7) or strategy (NT 6.5 / 7) - you can then access their data either via the BarsArray or their BIP context in your custom code -

Please note that you would also need a feed supporting indices data for this task - for example for NT7 those market statistics would be included in a real time subscription to our preferred market data vendor Kinetick.
