Post From: Incorrect realtime data

Attached is an example from Dec 9, 2019 in the evening, US Eastern Time. This is a 1-Trade periodicity chart with 'Combine Trades into Original Summary' turned on. ES-2019-12-GLOBEX. It wasn't a busy time in this market.

Note that the realtime readout shows duplicate trades of 166 buy contracts (left side of the image).

A delete and re-download of the same data shows the image on the right - a single 166 lot print. This is in agreement with a colleague's iqfeed tape, as well.

This isn't an isolated incident and has markedly increased over the last week or so.
