Strange minutes and daily data in 2016-07-29

[PatL]

A strange behavior is observed in many nasdaq traded stocks on Jul 29 2016. As the screenshot I provided, it only shows two trades, one at open and one at close.

I also checked daily data for AAPL on that date, I only see 2 trades (n = 2) with small volume (2.97M shares), but if you check yahood finance (Apple Inc. (AAPL) Stock Historical Prices & Data - Yahoo Finance) there are more than 110M shares traded on that date.

@PatL Thank you for reporting this. You were absolutely right, there was a data issue with symbols traded on Nasdaq (tape C) on that particular day. We fixed the issue, If you check now, you should see the correct bars.
