Post From: Questions about Volume at Bid/Offer data..

So, I use Ameritrade as my feed for Sierra.

I also have, at the same time, Ameritrade's TOS(think or swim) execution platform open on my desktop.

Today I did an A/B comparison of the T&S windows for TOS & Sierra and noticed that for the same data, one recorded it as going off on the bid while the other had it on the offer.

This was a constant finding throughout my time watching.

I would like to clarify this as the system I've been building is based off the assumption that this "Volume at bid/offer" data that I pay for through Sierra is accurate.

If Ameritrade is the provider for both datasets, how can this be possible?

Please advise..

Thanks,

J.
