Hi, so I encountered a troubling inconsistency today with how both TD Ameritrade and Sierra are relaying Volume at Bid/Offer data. I've attached the T&S windows for both platforms that show that Ameritrade listed this 100k trade on the Offer while Sierra listed it on the Bid. Which is correct..and why? Thanks, Jonathan
