NT added support for the Interactive brokers ^ADD symbol.
This is an unusal symbol in that uses the bid/ask/lasts to show show Advancers/Decliners/unchanged
The IB ^VOL symbols is similar. Bid has up-volume, Ask has DownVolume, Last has unchanged
NT will show the bid/ask but not last for this symbol in a MarketAnalyser.
Does not show anything in a chart. Whereas ^ADD plots fine.
See this link for a great explanation and example
