I may have missed it, but how "real-time" are these trades?
For those trades that appear to be in the last few days, how is it being tracked?

The reports are public so you can scroll through them, the most common pattern (I'm just eyeballing it I haven't found their download to graph it out properly) looks like they just do bulk reports every 30 days so you actually get a mix of old and new trades in each report.
