Post From: NQTV volumes still exceptionally lower

The new consolidated tape data feed we will offer for US equities, according to volume, should be the same as what we have with the Sierra Chart Exchange Data Feed.

@Sierra, I recall in earlier threads you mentioning the accuracy of the Nasdaq TotalView Bid/Ask volumes is significantly better than the SC Exchange Data "consolidated" feed. (With Tapes A/B/C, I can appreciate how error prone data in a consolidated feed might be) . When you talk about potentially rolling out a hybrid TotalView + Consolidated volume feed, will this new feed -in terms of bid/ask volumes- use TotalView data and just scale up the values by referencing the consolidated volume?

For example, let's say the TotalView feed by itself has a bar with a bid volume of 2,000 and an ask volume of 3,000 and a total volume of 7,000. Let's say the consolidated tape says the bar total volume is actually 10x more at 70,000. Would the potential TotalView + consolidated hybrid feed then 10x it's native bid volume to 20,000 and it's ask volume to 30,000. Is that how this potential new feed will work?
