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? |
