I bought a bunch of data from TickWrite and imported it into NT7. The data was in tick granularity, and covers Jan 2016 - Dec 2019. No issues here.
When I connect to my data provider (Rithmic), and open a 6 month chart (Volume data series), I can see that it's re-downloading data that covers part of 2019 as well.
How does the data from the 2 providers "mesh"?
Would Rithmic delete TickWrite's data, and replace with its own, or both sets are loaded into the database, in which case we'll get twice the volume, and completely mess up any Volume readings?
Any insights into this is much appreciated.
Thanks.
