What is Regional Market Data?

< 1 min read

DAS Trader’s Regional Market Data feed contains the “top of book” quotes from US equity exchanges. “Top of book” means the best quote on the exchange, which is typically the closest to the National Best Bid/Offer (NBBO) if they do not have current quotes matching the NBBO. Regional data does not include odd lot quotes.

These are the exchanges included in the regional market data feed:
